22 Proven Ways to Increase Brain Blood Flow

Without a doubt, healthy blood flow is absolutely essential for optimal brain function and mental health.

Brain blood flow, or cerebral blood flow, refers to the blood supply that reaches your brain during a given period of time. 

Your brain needs almost 20% of the blood supply provided by each heartbeat.

A steady flow of blood brings oxygen, glucose and nutrients to the brain, and carries carbon dioxide, lactic acid, and other metabolic waste products away from the brain.

But when blood flow to the brain is hindered, cognitive problems can arise.

Poor brain blood flow and circulation are linked to a number of brain and mental illnesses, including:

• Cognitive dysfunction and brain fog (131-132)

• Chronic fatigue syndrome (140)

• Dementia (133)

• Parkinson’s Disease (134)

• Alzheimer’s disease (135, 143)

• Depression (136)

• Post-traumatic stress disorder (PTSD) (137-139)

• Anxiety (139)

• Obsessive-compulsive disorder (OCD) (139)

• Panic disorder (139)

• Agoraphobia (139)

• Traumatic brain injury (141-142)

• Lyme disease (144)

“Increasing blood flow to the brain might be an effective therapeutic approach to prevent or treat Alzheimer’s.”

— Dr. Robert Vassar

Some of the main causes of poor brain blood flow include abnormal blood pressure, poor circulation, low thyroid, infections, and stress (126-130). 

Besides addressing these major causes, there are several ways to directly increase the amount of oxygen-rich blood that flows to your brain.

Researchers use neuroimaging techniques, such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET), to measure cerebral blood flow.

And they have found that the following 22 methods increase brain blood flow and circulation in humans. 

After suffering multiple concussions, I had severe depression and brain fog. So I had no choice but to focus on optimizing brain blood flow and circulation.

Many of these methods have been helpful to me over the years.

If you want to naturally increase blood flow to your brain, continue reading to learn more.

1. Exercise

Exercise is one of the best and most accessible ways to increase brain blood flow and circulation. 

Research shows that moderate exercise increases blood flow to the brain by as much as 15% (1). 

And you don’t even need to work out intensely to increase blood flow to your brain.

Simply walking for 30 minutes at a brisk pace, three or four times each week, is good enough. That will get more blood and oxygen to your brain and you’ll reap the benefits (2). 

In fact, the foot’s impact on the ground while walking sends pressure waves through the arteries, which sends more blood and oxygen to the brain (3). 

“There are many studies that suggest that exercise improves brain function in older adults, but we don’t know exactly why the brain improves. Our study indicates it might be tied to an improvement in the supply of blood flow to the brain.”

— Dr. Rong Zhang

Exercise has also been shown to protect against cognitive decline and dementia, promote neurogenesis, help reverse brain damage, and promote the regeneration of myelin.

So not surprisingly, exercise is recommended by many experts and it’s often their number one piece of advice for optimal brain health.

My usual advice is to find a sport or exercise routine that you enjoy, so that you’ll stick with it consistently.

2. Cold Exposure

Exposing yourself to cold temperatures can also help you get more blood flowing to your brain. 

Research shows that putting your hand in ice water for one minute can significantly increase the speed of blood flow to the brain (6-8). 

Researchers have also found that cooling the skin during upright tilting maintains the speed of blood flow to the brain (5). 

Animal studies also show that cold exposure significantly increases cerebral blood flow (4). 

I take a cold shower every day, and often go outside with minimal clothing in the winter to increase my blood flow and circulation. 

You don’t have to do that right away though. You can take it one baby step at a time.

You can start out by finishing your next shower with just 30 seconds of cold water.

See how you feel, and then work your way up to longer.

It can be a bit painful, but you get used to it and the beneficial effects are worth it.

Another way to ease yourself into it is by sticking your face, hand or foot in ice cold water.

Cold exposure also stimulates the vagus nerve and supports the endocannabinoid system. 

3. Sunlight

Research also shows that light stimulates brain blood flow and circulation.

Positron emission technology (PET) measures blood flow to specific areas of the brain.

In one study, researchers used PET scans to monitor cerebral blood flow in patients with season affective disorder (SAD) – before and after light therapy. 

Before light therapy, the scans show that patients had reduced blood flow to the cerebral cortex, the “executive” part of the brain.

But after just a few days of light therapy, this part of the brain started to light up, indicating greater activity and increased blood flow (9).

But this isn’t just seen in depressed individuals.

Another study found that 10 minutes of light exposure can increase brain blood flow in healthy people (10). 

Light therapy even increases brain blood flow in pre-term infants (11). 

I personally get sunlight every day during the spring and summer months to support my brain health. It’s a simple way for me to increase blood flow to my brain every day.

Researchers have also found a positive correlation between Vitamin D levels and brain blood flow (94).

So I take a Vitamin D3 supplement during the winter months when there isn't enough sun.

It's important to test and monitor your Vitamin D levels before and after supplementing with it.

4. Ginkgo Biloba

Ginkgo Biloba is a plant that has been used for thousands of years to treat a number of health problems.

Today, it’s one of the most popular herbal supplements in the world.

Doctors even prescribe it in Germany!

It’s most commonly used to improve brain health.

Researchers have found that it increases cognitive function, and improves memory and attention in both healthy and unhealthy individuals. It even reduces the risk of dementia and Alzheimer’s disease (15). 

These positive effects are mainly because it significantly increases blood flow to the brain and increases blood circulation in the brain (12-14). 

Gingko biloba is included in the Optimal Brain supplement. 

5. Low-Level Laser Therapy (LLLT)

Low-level laser therapy (LLLT), or photobiomodulation, is a treatment that uses red and infrared light to support brain function.

The treatment uses either low-power lasers or light-emitting diodes (LEDs) that emit red and infrared light.

The red and infrared light is applied to the brain, and it stimulates brain cells, helping them helping them function better.

Most doctors are clueless about LLLT; but not every doctor. 

Dr. Norman Doidge, a physician who teaches at the University of Toronto here in Canada, discusses the amazing effects of LLLT in his book The Brain’s Way of Healing.

One way LLLT can help the brain is by increasing brain blood flow and circulation. 

One study found that applying near infrared light to the forehead can help treat depression and anxiety (without side effects) by increasing frontal regional cerebral blood flow (49).

Another study saw improvement in brain blood flow in healthy elderly women (50). 

Animal research has also found that light can be used to locally increase brain blood circulation (93). 

I previously wrote about my experience with low-level laser therapy here.

I have used the Optimal 1000 Brain Photobiomodulation Therapy Light (Combo Red/NIR) and shine the red and infrared light directly on my forehead. It’s a simple way for me to quickly and naturally increase blood flow to the brain.

When I’m travelling and away from home, I take this smaller and more convenient device with me and shine it on my forehead.

I’ve also used the Vielight Neuro Duo, which is a transcranial-intranasal headset with 810 nm of near infrared light. It penetrates deeper into brain tissue and is absorbed better by the central nervous system. If you decide to try a Vielight device, you can use the coupon code JORDANFALLIS for a 10% discount

LLLT can also support thyroid function and mitochondria function and help with brain fog. 

6. Vinpocetine

Vinpocetine is a compound from the Periwinkle plant. 

It’s commonly used in Europe to treat cognitive decline, memory impairments, stroke recovery, and epilepsy.

Researchers have found that it increases brain blood flow in both healthy people and stroke victims.

The increase in brain blood flow leads to increased brain oxygen levels and energy production, reduced brain inflammation, and improved reaction time (16-25). 

I took a vinpocetine supplement many years ago after my last concussion to increase blood flow to the brain and speed up my recovery. But I no longer need to take it.

7. Meditation

Meditation is my favourite relaxation technique and it's linked to increased blood flow in the brain.

In one study, 14 people with memory problems followed a simple 8-week meditation program. And researchers found a significant increase in blood flow to the prefrontal cortex (31). 

Logical memory and verbal fluency also improved after training (31). 

Another study showed that just five days of meditation (30 minutes each day) significantly enhanced brain blood flow (32). 

I have used the Muse headband to meditate. It gives you real-time feedback while you meditate. That way, you know how well you are meditating. It makes meditating much more enjoyable.

I previously wrote about it here, and you can get it through the Muse website.

8. Resveratrol

Resveratrol is a beneficial antioxidant and anti-inflammatory compound.

Many people know that it’s found in grapes, red wine, raspberries and dark chocolate.

Resveratrol is known to help prevent the development of neurodegenerative diseases.

And researchers are starting to understand why.

Resveratrol can increase BDNF, help restore the integrity of the blood-brain barrier, and support your mitochondria.

But it can also help you quickly get more blood and oxygen flowing to your brain. 

In one study, after taking either 250 or 500 milligrams of resveratrol, study participants experienced a dose-dependent increase in brain blood flow (26). 

Even just 75 mg has been shown to increase brain circulation and cognition (27, 29). 

And a recent study found that chronic resveratrol supplementation increases brain blood circulation in post-menopausal women, improving their cognition and mood (28, 30). 

Resveratrol is included in this supplement.

9. Dark Chocolate

Most people love chocolate, and your brain loves it too. 

Dark chocolate contains cocoa, which is known to improve blood flow. 

It's one of my favourite foods, and it’s included in my Free Grocery Shopping Guide for Optimal Brain and Mental Health.

Research suggests that the flavonoids found in cocoa beans increase blood flow to key areas of the brain for two to three hours after eating them. And this leads to an improvement in cognitive performance and general alertness (33, 35). 

“Certain food components like cocoa flavanols may be beneficial in increasing brain blood flow and enhancing brain function among older adults or for others in situations where they may be cognitively impaired, such as fatigue or sleep deprivation.”

— Dr. Ian A. Macdonald, PhD, from the University of Nottingham Medical School in the United Kingdom

One study found that flavanol-rich cocoa significant increases the speed of brain blood flow in healthy elderly people (34). 

Another study found that drinking two cups of hot chocolate a day for 30 days was linked to improved blood flow to the brain and better memory (36). 

Dark chocolate also increases BDNF and reduces cortisol.

It’s important to choose a type of dark chocolate with at least 70 percent cocoa.

10. Omega-3 Fatty Acids

Omega-3s fatty acids are the highest quality fats for the brain.

They are essential, meaning your body cannot create them and you have to get them from food or supplements.

Making sure you get more omega-3s is one of the most important actions you can take to support your brain and nervous system.

Many studies show that they significantly reduce brain inflammation; improve memory, mood and cognition; and protect against mild cognitive impairment, dementia and Alzheimer's disease.

They also naturally increase brain blood flow and circulation. 

Research shows that higher omega-3 levels are significantly correlated with higher regional cerebral blood flow (37). 

“This is very important research because it shows a correlation between lower omega-3 fatty acid levels and reduced brain blood flow to regions important for learning, memory, depression and dementia.”

— Dr. Daniel G. Amen, MD, Amen Clinics

And one study found that omega-3 supplementation, in comparison with placebo, significantly increased brain blood flow (38). 

Omega-3 fatty acids are found in cold water fish such as salmon, black cod, sablefish, sardines and herring.

These foods are included in my Free Grocery Shopping Guide for Optimal Brain and Mental Health.

Unfortunately, most people don't consume enough of these foods.

So supplementing with krill oil should be considered.

Krill oil is a special kind of fish oil that readily crosses the blood-brain barrier. I’ve tried tons of fish oil supplements, and I recommend krill oil over all the others.

11. Acupuncture

Acupuncture is an alternative treatment that has been shown to increase brain blood flow and circulation.

In a randomized controlled trial, 17 post-stroke patients did acupuncture or sham acupuncture for 20 minutes.

The researchers found that the speed of blood flow to both hemispheres of the brain significantly increased during and after acupuncture treatment (39, 42). 

Research has also shown that acupuncture can significantly improve cerebral blood flow and circulation in animals (40-41, 43). 

I’m a really big fan of auricular acupuncture, which is when the needles are inserted into ear.

In my experience, ear acupuncture is more effective than regular acupuncture. I’m not sure why. I’ve just personally noticed more benefits from ear acupuncture. 

I’d recommend trying to find an acupuncturist in your area who provides ear acupuncture.

Ear acupuncture really helped me the first time I weened off antidepressants. I was surprised.

At the end of each appointment, my practitioner would secure small black seeds on my ear. 

I have also used an acupuncture mat at home to relax before bed.

Acupuncture also stimulates the vagus nerve. 

12. Chewing Gum

Research reveals that chewing increases brain blood flow (44). 

As a result, chewing can improve cognitive performance and brain function, including working and spatial memory. It also increases the level of arousal and alertness during a cognitive task (45). 

If you chew gum, make sure it’s aspartame-free.

Chewing gum also reduces cortisol. 

13. Acetyl-L-Carnitine (ALCAR) 

Acetyl-L-carnitine (ALCAR) is an acetylated form of the amino acid carnitine. 

It’s known to help reverse neurological decline by increasing levels of acetylcholine in the brain.

It’s often used as a brain booster by people of all ages because it support brain cells and increases alertness.

It’s also been shown to be very effective at alleviating chronic fatigue and improving mood by supporting mitochondrial function.

Considering all of this, it’s not too surprising that researchers have also found that it can enhance brain blood flow in people who have had a stroke (46-47). 

ALCAR is included in the Optimal Brain supplement. 

Make sure you read this article to learn more about the remarkable benefits of ALCAR.

14. Nitrates

Nitrates are both naturally-occurring compounds found in soil and plants.

High levels of nitrates are found in foods such as beets, celery, cabbage, spinach, and other leafy green vegetables.

These foods are included in my Free Grocery Shopping Guide for Optimal Brain and Mental Health.

Research shows that a nitrate-rich diet can increase blood flow to the frontal lobe of the brain, improving cognitive function and protecting against cognitive decline (51-52). 

Beet juice is a particularly rich source of nitrates, and studies have found that it can help widen blood vessels and increase oxygen and blood flow to the brain (53-54, 56). 

A double-blind, placebo-controlled trial even found that beet juice can improve cognitive performance by increasing brain blood flow (55). 

“There have been several very high-profile studies showing that drinking beet juice can lower blood pressure, but we wanted to show that drinking beet juice also increases perfusion, or blood flow, to the brain. There are areas in the brain that become poorly perfused as you age, and that’s believed to be associated with dementia and poor cognition.”

— Dr. Daniel Kim-Shapiro, PhD

I don’t really enjoy the taste, but every so often, I’ll drink beet juice during cognitively-demanding tasks. 

15. Drink Less Coffee (Or Take Theanine)

Coffee is generally excellent for brain health. There is a lot of research showing it is very healthy and can be protective against dementia.

However, studies also show that if you want to get more blood flowing to your brain and within you brain, you’re better off avoiding or limiting caffeine. 

Researchers have found that caffeine significantly reduces brain blood flow by 20 to 30% depending on the study and dosage (74-77). 

The good news is that taking the amino acid theanine can reduce the negative brain blood flow effects of caffeine (78-79). 

That’s why I often take a theanine supplement when I drink coffee.

Theanine is included in this anti-anxiety supplement.

I also often take breaks from drinking coffee to normalize brain blood flow and circulation. 

Taking the herb rhodiola can make quitting caffeine much easier because it helps reduce withdrawal symptoms.

Lastly, you could also try supplementing with the whole coffee fruit, instead of just drinking coffee.

The coffee bean is usually separated from the coffee fruit for roasting. When this happens, the surrounding coffee fruit is then thrown away. 

That’s a problem because the coffee fruit contains several healthy compounds not found in coffee beans themselves.

In fact, scientists have discovered that ingesting coffee fruit concentrate significantly increases brain function. 

That’s why coffee fruit concentrate is included in Optimal Brain.

16. Piracetam

Piracetam is a “nootropic”, which means it’s a supplement that enhances cognition.

It provides a mild boost in brain function, and it’s regularly used in Europe, Asia and South America to treat cognitive impairment. 

A meta-analysis found that piracetam improves general cognition when supplemented by people in a state of cognitive decline (84). 

Research also shows that it can increase brain blood flow in humans and animals (85-91). 

I used to take piracetam every day but I don’t need it at all anymore.

Phenylpiracetam is an advanced version of piracetam and I found it to be even better because it improves mood and reduces anxiety. It’s also been shown to reverse the depressant effects of benzodiazepines (81-83).

Both piracetam and phenylpiracetam work best if you take them with a source of choline, such as CDP-Choline and Alpha GPC (80). 

17. Ketogenic Dieting

A ketogenic diet is a very low-carbohydrate diet.

To follow the diet correctly, you need to eat less than 50 grams of carbohydrates per day.

This means you need to avoid all carbohydrate-rich foods, including grains, sugar, and even potatoes, legumes and fruit.

When you restrict carbs this much, your body enters ketosis, a metabolic state in which your body and brain run on fatty acids and “ketones” instead of glucose.

Researchers have found that ketones are a therapeutic option in traumatic brain injury because they can increase brain blood flow by 39% (100). 

Studies have also shown that ketones increase cerebral blood flow by 65% in animals (103-104). 

Caloric restriction also increases ketones, which preserves cerebral blood flow in aging rats (102). 

I follow a ketogenic diet every so often, but not for long stretches of time due to hormone problems that can result from it.

18. Citicoline

Citicoline (also known as CDP-Choline) is one of the most bioavailable forms of choline.

You need to get choline from food. But most people don’t get enough because very few foods in the Western diet contain it.

That’s why supplementation is often necessary.

Citicoline is a supplemental form of choline that has anti-inflammatory and neuroprotective effects.

It enhances the synthesis of acetylcholine and dopamine (two neurotransmitters that are critical for optimal brain function) and increases the number of acetylcholine and dopamine receptors in your brain (105-110). 

It’s also been shown to improve cognitive function by increasing the rate of brain blood flow (114-116). 

A double-blind placebo-controlled study concluded that Citicoline improves cognitive performance in patients with Alzheimer’s disease by increasing brain blood flow (113). 

I found that citicoline improved my focus and mental energy. It's included in the Optimal Brain supplement. 

You can also find some choline in foods such as beef liver and egg yolks. These foods are included in my Free Grocery Shopping Guide for Optimal Brain and Mental Health.

But the effects of Citicoline are much more noticeable and immediate because it quickly passes the blood-brain barrier and supports your brain.  

Citicoline also promotes the regeneration of myelin, supports the blood-brain barrier, and helps reverse brain damage.

Make sure you read this article to learn more about the remarkable benefits of Citicoline.

19. Blueberry Juice

Drinking blueberry juice improves cognitive function in the elderly, according to research published (123-125). 

One way it improved brain health was by increasing oxygen levels and increasing blood flow to the brain.

The participants had improvements in working memory while doing cognitive testing.

“In this study we have shown that with just 12 weeks of consuming 30ml of concentrated blueberry juice every day, brain blood flow, brain activation and some aspects of working memory were improved in this group of healthy older adults.”

— Dr. Joanna Bowtell

The amount of juice in the study was equivalent to 230g of blueberries.

The researchers believe that the flavonoids in blueberries were responsible for the positive effects.  

20. Pyrroloquinoline Quinone (PQQ)

Pyrroloquinoline quinone (PQQ) is a vitamin-like enzyme and potent antioxidant found in plant foods that can improve cognitive function.

Researchers have found that supplementing with PQQ can increase blood flow to the prefrontal cortex (117-118). 

One study found that PQQ can prevent the reduction of brain function in elderly people, especially in attention and working memory, by increasing brain blood flow (119). 

21. Intranasal Insulin

Insulin is one of the hormones that significantly affects brain function.

It's been shown to pass the blood-brain barrier and act on insulin receptors directly within the brain.

In a new therapeutic approach, commercially-available insulin (Novalin R) is prepared and added to nasal spray bottles, and sprayed and inhaled through the nose to support brain and mental health.

Intranasal insulin has been reported to significantly enhance memory, increase mental energy, reduce brain fog, improve mood, and lower anxiety and stress levels.

One possible mechanism is by increasing brain blood flow and circulation.

Research shows that intranasal insulin increases regional cerebral blood flow in the insular cortex (120, 122). 

In a randomized, double-blinded, placebo-controlled, intranasal insulin improved brain blood flow in older adults (121).

If you’re interested in learning more, I previously wrote a full article about intranasal insulin.

22. Music

I previously wrote about how music naturally reduces cortisol, helps treat OCD, and increases dopamine and oxytocin. 

But now it looks like it also increases blood flow to the brain.

Researchers found that musical training or listening to music increases blood flow to the brain (145-146).

It’s even more effective when you’re learning or listening to music that you really enjoy.

23. BONUS: Other Promising Nutrients and Herbs

Researchers have found that the following compounds can increase cerebral blood flow in animals. But I couldn’t find any research showing that it will do the same in humans. However, they are worth experimenting with as many of them have been effective at supporting my brain and mental health over the years.

• Arginine (57-60)

• Vitamin E (61-64)

• Bacopa (65-66) – also improves memory

• Curcumin (67-68)

• Ginseng (69-70)

• Citrulline (71-72)

• Icariin (73) – also promotes neurogenesis

• Forskolin (95) – also helps with brain fog

• S-adenosyl-L-methionine (96)

• Quercetin (97-98)

• Taurine (99) – also lowers homocysteine

How to Actually Heal and Repair a Leaky Blood-Brain Barrier

“Blood-brain barrier leakage means that the brain has lost its protective means, the stability of brain cells is disrupted and the environment in which nerve cells interact becomes ill-conditioned. These mechanisms could eventually lead to dysfunction in the brain.”

— Dr. Walter H. Backes, Maastricht University Medical Center

A healthy, properly-functioning blood-brain barrier is absolutely critical for optimal brain and mental health.

The blood-brain barrier is a protective shield that surrounds your brain.

It acts as a gatekeeper and filter, allowing beneficial nutrients to cross over into your brain, and keeping unwanted molecules out of your brain.  

But in his book Why Isn’t My Brain Working, Dr. Datis Kharrazian explains that the blood-brain barrier can break down and become “leaky”.

This allows harmful substances to enter your brain, contributing to brain inflammation, which has been shown to cause cognitive problems and mental illness (92, 110-111).

Hyper-permeability of the blood-brain barrier and neuroinflammation have been linked to a number of different brain and mental health problems and symptoms, including depression, anxiety, cognitive impairment, brain fog, Alzheimer's disease, Parkinson’s disease, headaches, migraines, chronic fatigue syndrome, attention deficit hyperactivity disorder (ADHD) and schizophrenia (101-109). 

A number of factors contribute to “leaky brain”, including (93-100):

• Systemic inflammation

• Oxidative stress

• Autoimmune disease

• Chronic psychological stress

• Infections

• Head trauma

• Poor diet and food additives

• Disrupted circadian rhythm

• Intestinal permeability (leaky gut syndrome)

• Excess alcohol consumption

• Environmental toxins and heavy metals

• High blood sugar

• Poor brain blood flow

Needless to say, these things are very common today, so a lot of people likely have a leaky blood-brain barrier.

The good news is that even though the blood-brain barrier can break down and become leaky, it can also be fixed!

You can repair it if you give it what it needs to heal. 

After living in a moldy home and suffering multiple concussions, my brain and its barrier were in rough shape.

Since then, I’ve searched far and wide for solutions that could strengthen it.

Here are 24 strategies that have been shown to support and repair the blood brain barrier.

Many of them have helped me.

Together, they can help you reduce neuroinflammation, heal your “leaky brain,” and overcome your brain and mental health challenges. 

1. Avoid Gluten

Avoiding gluten is necessary for optimal brain and mental health.

I’m convinced that if you struggle with a chronic brain or mental illness, you should follow a strict gluten-free diet for at least 30 days and see how you feel.

You'll likely feel better.

There’s one main reason I recommend this…

Gluten has been shown to elevate “zonulin”.

Zonulin is a protein in your body that increases the permeability of the intestinal barrier and disrupts the blood-brain barrier (48).

Researchers have found that gluten clearly increases zonulin and contributes to “leaky gut” and “leaky brain”, resulting in neuroinflammation and altered cognitive function (49, 50).

Gluten sensitivity can also create visible changes to the white matter in your brain, according to research in The Lancet Neurology (51).

Yet unfortunately, the myth continues to spread that only people with celiac disease need to avoid gluten-containing food.

That’s simply not true.  

Dr. David Perlmutter, MD, author of Grain Brain and Brain Maker, explains:

“Not only is there increased gut permeability when the gut is exposed to gliadin, a protein found in gluten, but in fact the blood brain barrier also becomes more permeable in response to gliadin exposure.”

You should also determine if you have other food sensitivities and remove those foods from your diet as well. A lot of people are sensitive to dairy, along with gluten. I can't tolerate gluten, dairy and egg whites and have to avoid them completely. 

2. Heal Your Gut (and Increase the Good Bacteria Within It)

There is a clear connection between your brain and digestive system.

I’ve discussed this before.

Whatever happens in your gut directly impacts your brain function.

Because of this connection, it’s critical to address gut issues in order to heal a leaky brain.

Researchers have studied mice that are “germ free”.

“Germ-free” mice means that the mice don’t have any bacteria in their intestines.

And what did the researchers find?

They found that these germ-free mice had very leaky blood-brain barriers (56).

But when these germ-free mice received a fecal transfer, where researchers introduced bacteria into their intestines, the permeability of their blood-brain barriers decreased significantly (57).

So it’s becoming increasing clear that our gut bacteria directly affect the health of our blood-brain barrier.

And manipulating your gut bacteria, and increasing the amount of good bacteria in your digestive system, can help improve the integrity of your blood-brain barrier and heal your leaky brain. 

“Given that the microbiome composition and diversity change over time, it is tempting to speculate that the blood-brain barrier integrity also may fluctuate depending on the microbiome.”

— Dr. Sven Pettersson, MD, PhD

In my experience, this is true, as my brain functions much better when I take care of my gut. 

Eating more prebiotic fiber and resistant starch, taking a high-quality probiotic, and eating fermented foods on a regular basis can increase the amount of good bacteria in your gut.

I take Optimal Biotics every day.

You should check out my previous article about gut health to learn more.

And if you have depression or anxiety, taking these probiotics can help.

3. Drink Coffee

Coffee and caffeine are excellent for brain health. There is lots of research showing they are very healthy and can be protective against dementia.

One possible explanation for this is that caffeine supports the blood-brain barrier.

Studies show that caffeine protects against Alzheimer's disease and Parkinson’s disease by keeping the blood-brain barrier intact, and protecting against blood-brain barrier dysfunction and leakage (32).

In one study, researchers found that caffeine blocks the disruption of the blood-brain barrier, concluding that caffeine is “useful in the treatment Alzheimer's disease” (33, 34).

Another study showed that caffeine can protect against Parkinson’s disease and neurodegeneration by stabilizing the blood-brain barrier (35).

I used to not be able to handle any coffee and caffeine at all. But now that I have my anxiety under control, I can handle it just fine. I drink one cup of coffee most mornings.

Coffee and caffeine can disrupt sleep though, so make sure you don’t drink it later in the day. I have my last cup sometime between 10 in the morning and noon. If I have it any later than that, it disrupts my sleep.

There are also additional brain health benefits when you consume the whole coffee fruit, instead of just coffee or pure caffeine. 

Usually, coffee beans are extracted from the whole coffee fruit for roasting. And then the surrounding coffee fruit is then thrown away. 

But this is a problem because the coffee fruit contains several healthy compounds not found in coffee beans themselves.

And researchers have now discovered that ingesting whole coffee fruit concentrate significantly increases brain function.

That’s why I included coffee fruit concentrate in the Optimal Brain supplement. 

4. Sulforaphane

Sulforaphane is a phytochemical found in cruciferous vegetables such as broccoli, Brussels sprouts or cabbages.

It has potent antioxidant and anti-inflammatory actions.

It’s quite similar to curcumin.

Numerous studies have shown that sulforaphane can prevent the breakdown of the blood-brain barrier, reduce permeability of the blood-brain barrier, and improve cognitive function after stroke and traumatic brain injuries (87-91).

You can take sulforaphane in supplement form.

If you decide to take it as a supplement, make sure you get the "myrosinase-activated" form.

Myrosinase is the enzyme in broccoli that helps metabolize sulforaphane.

I once bought a supplement that didn't contain myrosinase and had to return it, and then ended up buying another one instead.

5. Avoid Alcohol

Not surprisingly, alcohol and acetaldehyde – a byproduct of alcohol metabolism – can weaken and damage the blood-brain barrier, and contribute to leaky brain.  

Researchers have found that the oxidative stress that results from excess alcohol consumption leads to blood-brain barrier dysfunction (58, 59).

And this can then lead to neuroinflammation (60).

There are ways to protect your brain from alcohol, but you’re better off avoiding it completely or significantly reducing your consumption if you’re trying to heal.

Some types of alcohol are better than others. You can learn more about the best types of alcohol here. 

 6. Resveratrol or Pterostilbene

Resveratrol is a beneficial antioxidant and anti-inflammatory compound found in grapes, red wine, raspberries and dark chocolate.

It’s known to help prevent the development of neurodegenerative diseases.

And scientists are starting to understand why.

Resveratrol can increase BDNF and support your mitochondria.

And according to cutting-edge research, it can also protect and support your blood-brain barrier.

In a recent study, researchers gave resveratrol to Alzheimer’s patients and it restored the integrity of their blood-brain barriers.

Because of this, there was a reduction in brain inflammation, which slowed down cognitive decline in the patients (38, 39). 

Numerous other studies have found that resveratrol:

• Significantly reduces the breakage, damage and dysfunction of the blood-brain barrier;

• Defends and protects the blood-brain barrier; and

• Improves and maintains the overall integrity of the blood-brain barrier (36-37, 40-43).

“Resveratrol imposes a kind of crowd control at the border of the brain. The agent seems to shut out unwanted immune molecules that can exacerbate brain inflammation and kill neurons.”

— Dr. Charbel Moussa, MD, PhD

Because of resveratrol’s ability to stabilize the blood-brain barrier and protect against neuroinflammation, researchers also believe it may reduce the clinical severity of multiple sclerosis (44).

Lastly, resveratrol has been shown to protects against oxidized LDL-induced breakage of the blood–brain barrier (45, 46).

So clearly resveratrol is great for our blood-brain barriers.

If resveratrol was a pharaceutical drug, we would definitely be hearing more about it. But natural compounds cannot be patented, so we don't.  

Pterostilbene, a compound found in blueberries, is very similar to resveratrol.

It’s also been shown to protect the blood-brain barrier by reducing oxidative stress, and it’s apparently better absorbed than resveratrol. In fact, it’s commonly referred to as a “better resveratrol” (47).

I tried pterostilbene and it was beneficial, but I didn’t find it any more helpful than resveratrol, so I’ve decided to just stick with resveratrol considering it has significantly more research to back it up. 

Resveratrol is included in this supplement.

7. Reduce Stress

I highly recommend you try to do something every day to manage and reduce your stress.

Research suggests that acute stress damages the blood-brain barrier (52).

And extreme stress has been shown to increase inflammation and increase the permeability of the blood-brain barrier (53-55).

But normalizing your stress levels can help the blood-brain barrier repair itself.

The most effective way to significantly reduce your stress and anxiety is neurofeedback. It’s advanced, guided meditation and I previously wrote about my experience with it here.

If you can’t access neurofeedback, taking up a daily meditation practice is an excellent idea.

I’m a big fan of the Muse headband. It’s a device that guides you while you meditation. Similar to neurofeedback, it gives you real-time feedback while you meditate. I wrote an entire review about it here, and you can get the device through the Muse website. 

Regular massage, acupuncture, eye movement desensitization and reprocessing (EMDR), emotional freedom techniques (EFT), heart-rate variability (HRV) training, and an acupressure mat have helped me a lot as well.

Lying on an acupressure mat while using my EmWave2 for just 10 minutes relaxes my entire body and mind. I do this at night before bed.

Some nutrients and herbs that can help you with stress include zinc, magnesium, ashwagandha and phosphatidylserine.

This anti-anxiety supplement also includes a number of natural compounds that have helped me manage my stress over the years.

8. Omega-3 Fatty Acids

Omega-3 fatty acids are essential fats that your body cannot produce itself. So you need to get them from diet or supplements, as they are absolutely necessary for the normal functioning of your brain and nervous system.

Omega-3 fatty acids can support your mitochondria, increase your BDNF levels, and help you overcome addiction and withdrawal.

But they can also support your blood-brain barrier.

Researchers have found that omega-3 fatty acids can: 

• Reduce damage to the blood-brain barrier after stoke;

• Limit blood-brain barrier disruption after traumatic brain injury; and

• Benefit people with multiple sclerosis by indirectly reducing disruption of their blood-brain barriers (76-78).

Wild fish is the best food source of omega-3 fatty acids, but unfortunately, most people don't consume enough omega-3 fatty acids through their diet.

That’s why I recommend supplementing with krill oil, a special kind of fish oil that contains the essential omega-3 fatty acids.

Krill oil also contains astaxanthin, a powerful, naturally occurring carotenoid.

Astaxanthin has also been shown to decrease inflammation and protect the blood-brain barrier (118-119).

9. Sleep and Melatonin

Deep sleep is necessary for the optimal functioning of your blood-brain barrier.

My sleep used to be terrible and it was one of main factors that contributed to my poor brain and mental health. And then my poor brain and mental health would make my sleep worse. So it was a vicious cycle.

Sleep restriction has been shown to impair the functioning of the blood-brain barrier and increase its permeability (84).

So you should really try to get at least 7 hours of high-quality, restorative sleep every night.

Supplementing with melatonin can also help.

Melatonin is a hormone released by your pineal gland, a small gland in your brain. Melatonin helps control your sleep and wake cycles (circadian rhythm).

Adequate levels of melatonin are necessary to fall asleep quickly and sleep deeply throughout the night.

Research also shows that melatonin can stabilize the blood-brain barrier and prevent damage caused by traumatic brain injury (85, 86).

This sleep supplement contains magnesium and a number of other natural compounds that I’ve used over the years to promote the production of melatonin.

But I work with my clients so that they can naturally produce more melatonin and maximize the quality of their sleep without so many supplements. We have free online workshop that talks about how you can work with us. You can register for the workshop here.

10. Berberine

Berberine is an alkaloid extracted from various plants. 

It has anti-inflammatory, neuroprotective and possibly antidepressant effects. It can also improve intestinal health and lower cholesterol.

And several studies have shown that it can decrease the permeability of the blood-brain barrier and reduce brain damage after traumatic brain injury. It does this by suppressing inflammation (23-26). 

I’ve experimented with varying dosages of berberine. I personally didn’t notice any profound brain and mental health benefits, but I have heard good things about berberine from other people. 

11. Avoid Environmental Mold and Mycotoxins

Environmental mold can be a serious problem for some people.

Unfortunately, most people aren’t even aware that mold is in their home or workplace and affecting their brain function.

In water-damaged buildings, mycotoxins (toxic metabolites produced by mold) are released into the air.

If you’re genetically susceptible, they can wreak havoc on your brain, and your cognitive function and mental health can deteriorate for no apparent reason.

One way mold and mycotoxins can disrupt brain function is by causing “leaky brain.”

Researchers have discovered that mycotoxins can clearly reduce the integrity of the blood-brain barrier (62).

They’ve also concluded that exposure to mycotoxins in an indoor environment can cause neurological damage. One way it does this is by breaking down the blood-brain barrier (61).

Several other studies have found that mycotoxins increase the permeability of blood-brain barrier and disrupt the functioning of the nervous system (63-66).

I lived in a moldy house for more than a year, and my blood-brain barrier likely became significantly leaky during that time, as my brain and mental health deteriorated. I also suffered a terrible concussion while living in that house, making my brain even more permeable. It took a while to get back to normal.

Today I use an air filter in my apartment to protect myself from any mold. It removes any mold spores and smoke that may be in the air.

Mycotoxins aren’t just in your environment though. Low amounts of mycotoxins are also often found in some seemingly healthy foods, such as tea, nuts, coffee and chocolate. I recommend finding the freshest, highest-quality, organic versions of these foods.

If I'm exposed to mold or their toxins, I supplement with activated charcoal or bentonite clay. Activated charcoal and bentonite clay are potent natural treatments that can trap toxins and chemicals, allowing them to be flushed out of your body.

12. B Vitamins

Several B vitamins have been shown to support the blood-brain barrier and help heal leaky brain.

Vitamin B1 (thiamine) deficiency disrupts the blood-brain barrier, and supplementing with Vitamin B1 restores its integrity (80-81).

Researchers have also found that vitamins B12, B6, and B9 (folate) can restore the integrity of the blood-brain barrier in adults that have elevated homocysteine levels and mild cognitive impairment. Homocysteine is an inflammatory compound that can contribute to blood-brain barrier breakdown at high levels, and the B vitamins normalize homocysteine levels (82-83).

A number of B vitamins are included in this supplement.

13. Magnesium

Magnesium is a vital mineral that plays a key role in more than 300 biochemical reactions in your body.

It impacts your neurotransmitters and hormones, both of which can significantly impact your mood and brain function.

Magnesium is one of the three nutrients that I think everyone should be taking for their brain, because most people are deficient nowadays.

Research shows that it can support your mitochondria, protect your brain from alcohol, increase your BDNF levels, and help you overcome addiction and withdrawal.

And there is plenty of research showing that it can protect and support your blood-brain barrier as well.

Multiple studies have found that magnesium protects the blood-brain barrier, prevents its disruption, and significantly reduces hyperpermeability of the blood-brain barrier (27, 28, 31).

One study found that it decreases blood-brain barrier permeability by 41% (29).

Magnesium’s protective effect against blood-brain barrier hyperpermeability has also been seen after traumatic brain injury (30).

Foods that contain magnesium include spinach, chard, pumpkin seeds, almonds, avocado, dark chocolate and bananas. These foods are included in my Free Grocery Shopping Guide for Optimal Brain Health.

But supplementation and taking Epsom salt baths is still necessary for most people because magnesium is rapidly used up during times of stress and certain psychiatric drugs can deplete magnesium.

14. Alpha Lipoic Acid (ALA)

Alpha Lipoic Acid (ALA) is an antioxidant produced by your body.

It can also be taken as a supplement.

ALA is fat soluble and can easily cross the blood-brain barrier to protect your brain (1-3).

As I’ve discussed before, it can protect your brain from alcohol and support the mitochondria in your brain.

But not only can it cross your blood-brain barrier and support your brain; it can also support your blood-brain barrier itself.

Studies show that ALA has neuroprotective effects, and it maintains the integrity of the blood-brain barrier by reducing oxidative stress (4-5)

Researchers also point out that its anti-inflammatory and antioxidant effects can stabilize the blood-brain barrier. This makes it an “attractive therapeutic agent for the treatment” of multiple sclerosis and traumatic brain injury (6-8).

ALA is included in the Optimal Antiox supplement.

15. Acetyl-Carnitine (ALCAR)

Acetyl-L-carnitine (ALCAR) is an acetylated form of the amino acid carnitine.  

It’s been shown to have neuroprotective and cognitive-enhancing effects. It’s often used as a natural brain booster because it increases alertness and provides support to brain cells.  

ALCAR has also been shown to be very effective at alleviating chronic fatigue and improving mood. It helps reverse neurological decline and supports mitochondria function as well. 

It does so much, so not surprisingly, researchers have also found that ALCAR helps repair the blood-brain barrier by reversing mitochondria decay caused by oxidative damage (122).

I find that ALCAR personally gives me a big boost in mental energy and cognitive function.  

That’s why it’s included in the Optimal Brain supplement. 

Make sure you read this article to learn more about the remarkable benefits of ALCAR.

16. Curcumin

Curcumin is the most heavily researched compound within turmeric, the spice that gives curry its yellow colour.

Curcumin is one of my favourite compounds for the brain. It can lower your cortisol levels and increase your BDNF levels.

But it can also:

• Reduce the disruption and hyperpermeability of the blood-brain barrier;

• Reverse blood-brain barrier dysfunction; and

• Improve the overall integrity of the blood-brain barrier (13-18).

Studies have also shown that curcumin can prevent blood-brain barrier damage and reduce the permeability of the blood-brain barrier caused by oxygen and glucose deprivation (20-22).

Researchers believe it can do all of this because it significantly reduces inflammation and oxidative stress (19).

Curcumin can be found in this supplement.

17. Vitamin D

Vitamin D is a fat-soluble vitamin that your skin synthesizes when it’s exposed to the sun.

Every tissue in your body has vitamin D receptors, including the brain, heart, muscles, and immune system.

This means your entire body needs it to function properly and a deficiency can lead to costly physiological and psychological consequences.

Researchers have found that Vitamin D can prevent the disruption of the blood-brain barrier, mainly by reducing inflammation (72, 73).

In patients with multiple sclerosis, Vitamin D has been shown to protect endothelial cells and reduce blood-brain barrier disruption (74).

And one study found that intranasal administration of vitamin D reduces blood–brain barrier disruption (75).

I personally take a Vitamin D3 supplement to make sure my Vitamin D levels are optimal.

It's important to test and monitor your Vitamin D levels before and after supplementing with it.

18. Citicoline or Alpha GPC

Choline is an essential nutrient that most people don’t consume enough of because very few foods in the Western diet contain it.

Citicoline (also known as CDP-Choline) is the most bioavailable supplemental form of choline.

As I’ve discussed before, it can help you overcome brain fog and addiction.

But it’s also been shown to significantly decrease the disruption and breakdown of the blood-brain barrier after traumatic brain injury (11-12).

And after brain ischemia, Citicoline significantly reduces blood-brain barrier dysfunction (10).

I personally take Citicoline every day.

It helps me a lot because I’ve had multiple concussions. 

Make sure you read this article to learn more about the remarkable benefits of Citicoline.

Alpha GPC is another excellent form of choline that has been shown to support the blood-brain barrier.

Researchers have found that it improves cognitive function by reversing the changes to the blood-brain barrier after a brain injury (9).

Make sure you read this article to learn more about the benefits of Alpha GPC, the optimal dosage, and the best way to take it.

You can find some choline in beef liver and egg yolks, but both Citicoline and Alpha GPC have much more noticeable and immediate effects.  

Both citicoline and Alpha GPC are included in the Optimal Brain supplement. 

19. Reduce Exposure to Electromagnetic Fields (EMFs)

“I have no doubt in my mind that, at the present time, the greatest polluting element in the Earth’s environment is the proliferation of electromagnetic fields.” - Dr. Robert Becker, Nobel Prize nominee and author of The Body Electric: Electromagnetism And The Foundation Of Life

An increasing amount of research is showing that radiofrequency electromagnetic fields emitted from Wi-Fi, laptops, and cellphones can negatively affect the brain and produce widespread neuropsychiatric effects including depression.

It’s an inconvenient truth that needs to be talked about, rather than downplayed, ignored and dismissed.

One way that radiofrequency EMFs may be causing neuropsychiatric effects is by contributing to a "leaky brain".  

Several studies have found that EMFs emitted from cellphones increase the permeability of the brain-blood barrier, and this increased permeability may lead to the accumulation of brain tissue damage and cognitive impairment (112-114). 

I encourage you to check out my other post about EMFs here. 

I'm still learning about how to manage and combat them, but here are some initial steps you can take:

• Get an EMF meter to determine your exposure. I use the Cornet ED88T. It's the best option that is currently available. It measures electric, magnetic and radiofrequency fields. It's like having three meters in one. You can get it here.

• Put your phone on airplane mode when you’re not using it and/or use a radiation-blocking phone case such as Safe Sleeve. I did a lot of research into radiation-blocking cases and Safe Sleeve is the best on the market. They are manufactured with materials that have been 3rd-party tested to block 99.9% of radiation coming off a cell phone.

• Turn off Wi-Fi at night while you’re sleeping.

• If you have a laptop, don’t touch it. Use a wired keyboard and wired mouse instead.

• Supplement with the herb Rhodiola. It has radioprotective effects (60-62). I previously wrote about it here.

This is just the tip of the iceberg. There are many other steps you can take, and I plan on writing more about this soon because it isn’t discussed enough.

This may seem like “woo-woo” but it’s a real issue. And I suspect it will eventually become one of the biggest issues of our time.

20. Lower Homocysteine

Homocysteine is an amino acid that is produced in the body as a result of methylation.

In healthy people, it’s properly metabolized and normal levels are maintained. 

But when homocysteine isn’t properly metabolized, it can build up inside the body and levels can become too high.

And that’s when homocysteine becomes dangerous and unhealthy. 

At high levels, homocysteine is inflammatory, and research shows it increases permeability of the blood-brain barrier (115).

You can check your homocysteine levels by ordering this blood test. 

If you test and find out your levels are high, check out this article for 16 ways to lower your homocysteine levels.

Normalizing homocysteine not only helps the brain recover from physical damage, but also reduces depression and cognitive decline.

21. Progesterone

Progesterone is a natural steroid and sex hormone involved in the menstrual cycle and pregnancy.  

It has a variety of important functions in the body, and even plays an important role in brain function.  

Research has found that progesterone supports the normal development of brain cells and protects them from damage. 

And one study shows that it reduces inflammation and can support the blood-brain barrier after brain injury (120).

In addition to its role as a natural hormone, progesterone can be taken as a medication, usually by women during menopause as part of their hormone replacement therapy. 

22. Increase Brain Blood Flow

Brain blood flow, or cerebral blood flow, refers to the blood supply that reaches your brain during a given period of time. 

Your brain needs almost 20% of the blood supply provided by each heartbeat.

A steady flow of blood brings oxygen, glucose and nutrients to the brain, and carries carbon dioxide, lactic acid, and other metabolic waste products away from the brain.

But when blood flow to the brain is impaired, problems can arise, including a leaky blood-brain barrier.

Research shows that lack of brain blood flow increases oxidative stress, damages the blood-brain barrier, and increases blood-brain barrier permeability (116-117).

Be sure to check out this post for 21 ways to increase blood flow to the brain.

23. Vagus Nerve Stimulation

The vagus nerve is the longest cranial nerve in your body and part of your parasympathetic “rest and digest” nervous system.

Research shows that stimulating the vagus nerve can decrease blood-brain barrier disruption.

In fact, researchers have found that vagus nerve stimulation can prevent the increase in blood-brain barrier permeability after a traumatic brain injury, and reduce it after a stroke (123-124).

So how do you stimulate your vagus nerve naturally?

I previously provided 13 ways to activate your vagus nerve in this post.

Deep breathing with the EmWave2 device is my favourite way. 

24. Intermittent Fasting

Fasting is another great way to strengthen your blood-brain barrier.

It allows your digestive system to take a break, and triggers a number of hormones that boost your body’s ability to repair itself.

Ghrelin, a hunger-stimulating hormone, signals to your body that it’s time to eat. And it increases when you are fasting.

Researchers have found that that ghrelin improves the integrity of the blood-brain barrier and reduces the breakdown of the blood-brain barrier after a traumatic brain injury (125).

As a result, fasting can help treat neurological conditions and lowers the risk of cognitive decline and neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease.

This is why I personally eat all my food for the day within an 8-hour window, and then fast for the other 16 hours of the day.

You don’t need to go that long, but you should try to fast for at least 12 hours at a time.

The best way to get started is simply by eating dinner around 6, not eating anything after that before bed, and then eating a regular breakfast the next day.

That should give you about 12-14 hours of fasting time.

25. BONUS: Other Nutrients, Antioxidants and Herbs

Here are several other nutrients, antioxidants and herbs that have been demonstrated to support the blood-brain barrier.

I’ve decided to not write about these in-depth because there isn’t as much research to back them up.

That doesn’t mean they aren’t useful though. They have still helped me: 

• Vitamin C (67)

• Iodine (68)

• Selenium (69)

• Vitamin E (69)

• N-Acetyl-Cysteine (70)

• Ginseng (71)

• Inositol (79)

• Ursolic Acid (121)

Conclusion

The brain has a remarkable ability to heal itself, and this includes the barrier that protects it.

The above steps have been proven to help repair and support the blood brain barrier, and I’ve noticed the benefits of implementing them into my own life.

I hope they help you too!

13 Powerful Ways to Support Your Thyroid & Mental Health

“When you know better, you do better.”

— Maya Angelou

Sometimes it may feel as if we have no control over our thoughts and emotions. Our minds can take on a life of their own, with no rhyme or reason as to why we're suddenly sad and anxious.

But there are always underlying causes of these mood swings, and with a better understanding of them, you can learn to manage and overcome them. 

Like I have, you can connect the dots, determine your underlying triggers, learn to control them and even completely eliminate them over time. 

So today I want to talk about thyroid dysfunction. It was one of the underlying issues of my chronic mental illness. 

Your thyroid is a small butterfly-shaped gland located in your neck below your Adam’s apple.

It’s one of your most important glands, producing hormones – thyroxine (T4) and triiodothyronine (T3) – which impact the health and functioning of your entire body.

In fact, normal metabolism and energy levels depend on these hormones. 

Your thyroid also plays a key role in the optimal health and functioning of your brain. It can impact your cognition, concentration, mood, memory and emotions. 

So when your thyroid hormones are out of balance, you can be too, and brain and mental problems can arise.

Your thyroid can either be overactive and produce too much thyroid hormone (hyperthyroidism), or underactive and produce too little thyroid hormone (hypothyroidism).

Hypothyroidism (low thyroid) is much more common, and since I personally struggled with symptoms of hypothyroidism, this post will mostly focus on that.

Hypothyroidism can also be caused by an autoimmune conditions called Hashimoto’s thyroiditis in which the body’s immune system attacks the thyroid tissue.

According to Dr. Datis Kharrazian, author of Why Isn’t My Brain Working? and Why Do I Still Have Thyroid Symptoms?, 90% of people with hypothyroidism have Hashimoto’s. 

Here are some of the common brain and mental health symptoms of low thyroid that I experienced:

• Chronic fatigue

• Brain fog

• Low mood

• Forgetfulness

• Weakness

• Sluggishness

Sounds just like depression, doesn’t it?

You Don't Have Mental Illness, You Have Thyroid Problems

Many studies show that people with cognitive, emotional and behavioural disturbances have lower levels of thyroid hormone than the general population, and their psychiatric symptoms improve when they take thyroid hormone.

The following symptoms and disorders have been linked to thyroid problems (69-86): 

• Depression

• Anxiety

• Bipolar disorder, mania and mood swings

• Irritability and rage

• Insomnia

• Paranoid schizophrenia and psychosis

• Dementia and confusion

• Social anxiety disorder

• Generalized anxiety disorder

• Borderline personality disorder

• Obsessive-compulsive disorder (OCD)

• Attention-deficit hyperactivity disorder (ADHD)

In fact, many people struggling with these conditions see better improvements when they are treated with thyroid hormone than when they are treated with psychiatric medication (and experience fewer side effects). 

“Psychiatric patients with subclinical hypothyroidism - especially those with incomplete responses to psychotropic therapy - should usually be treated with thyroid hormone. In some patients with no clear evidence of a biochemical or clinical thyroid disorder, mood symptoms nevertheless respond to thyroid hormone.”

— Thomas D. Geracioti Jr, MD

A number of different medical practitioners and researchers have written books about how thyroid problems can negatively affect brain and contribute to mental illness:

• “Brain cells have more thyroid hormone receptors than any other tissue, which means that a proper uptake of thyroid hormone is essential for the brain cells to work properly.” – Dr. Barry Durrant-Peatfield, MD, Author of Your Thyroid and How to Keep It Healthy

• “How much of what we call “mental illness” is actually thyroid-driven? In my experience, a vast majority.” – Dr. Kelly Brogan, MD, Author of A Mind of Your Own: The Truth About Depression and How Women Can Heal Their Bodies to Reclaim Their Lives

• "T3 [thyroid hormone] is actually a bonafide neurotransmitter. If you don’t have enough T3, or if its action is blocked, an entire cascade of neurotransmitter abnormalities may ensue, which can lead to mood and energy changes, including depression and anxiety.”– Dr. Christiane Northrup, MD, Author of Women's Bodies, Women's Wisdom: Creating Physical and Emotional Health and Healing

• “Scientists now consider thyroid hormone one of the major players in brain chemistry disorders. And as with any brain chemical disorder, until treated correctly, thyroid hormone imbalance has serious effects on the patient’s emotions and behavior.” – Dr. Ridha Arem, MD, Author of The Thyroid Solution: A Mind Body Program for Beating Depression and Regaining Your Emotional and Physical Health

• “There’s a very tight correlation between hypothyroidism and depression. Unfortunately, patients are misdiagnosed with depression when really they have low thyroid. There are well designed clinical trials to show you that your active thyroid hormone is essential to a happy mood. Correcting and nourishing the thyroid gland is absolutely imperative in order to improve mood.” – Suzy Cohen, Author of Thyroid Healthy: Lose Weight, Look Beautiful and Live the Life You Imagine

• “People with mental health issues have greater rates of thyroid antibodies and Hashimoto's. I've had so many clients who were misdiagnosed. They were on heavy-duty psychotropic medications. They were hospitalized. But it was their thyroid disorder that was causing their issues.” – Dr. Izabella Wentz, PharmD, Author of Hashimoto's Thyroiditis: Lifestyle Interventions for Finding and Treating the Root Cause

So if you struggle with brain or mental illness, you likely do not need a prescription for antidepressants, antipsychotics and anti-anxiety medication. What you really need is to support your thyroid. Treating the underlying thyroid problem is critical to alleviating the associated psychiatric symptoms.

Luckily, there are easy, natural ways for you to do just that.

Below are 13 main strategies I’ve used to balance my thyroid hormones and improve thyroid function. 

Before implementing all of them, I highly recommend getting a full thyroid panel so that you know your starting point.

1. Cut Out Gluten

Certain foods can disrupt proper thyroid function and you should avoid them to optimize brain and mental health. 

Gluten-containing grains (barley, wheat, rye, spelt) are the worst offenders.  

The problem with gluten is that it can increase intestinal permeability (leaky gut syndrome). When this happens, small particles of food can leak into your bloodstream. Your immune system sees these food particles as foreign entities and attacks them, increasing inflammation throughout your body. 

On top of this, the molecular structure of gliadin (the protein found in gluten) resembles that of the thyroid gland. So when gliadin enters your bloodstream, your immune system not only attacks the gliadin, but also your thyroid tissue because of its close resemblance. And this can cause many brain and mental health problems (11-13). 

Research shows that people with celiac disease and gluten intolerance are more likely to have thyroid diseases and mental illnesses, and vice versa (1-10). 

“Many people that have hypothyroidism really have gluten sensitivity. Over time, they actually have significant brain degeneration. When people degenerate their brain, one of the first things they get is depression.”

— Dr. Datis Kharrazian

Thyroid function, and therefore brain and mental health, will often improve after the elimination of gluten-containing grains. 

2. Eat Enough Calories and Carbohydrates

Making sure you eat enough calories and carbohydrates on a daily basis is critical for optimal thyroid and brain function.  

A landmark paper, known as the Vermont Study, found that thyroid hormone drops when you don’t eat enough calories and carbohydrates (14). 

Several other studies also show that ketogenic low-carb diets can suppress thyroid function and reduce thyroid hormone. This is because carbohydrates play a key role on the production of thyroid hormone (15-18). 

In previous posts, I have mentioned that fasting and ketogenic dieting can have beneficial effects on your brain. This is still true. However, it's important to note fasting and low-carb diets should be followed intermittently and not consistently over long stretches of time, mainly because of their detrimental effects on the thyroid. I prefer to take exogenous ketones instead. They immediately increase my mental clarity without having to restrict carbohydrates. 

My Free Grocery Shopping Guide for Optimal Brain Health contains plenty of healthy, nutrient-dense sources of carbohydrate, including:

• Yams

• Squash

• Potatoes

• Carrots

• Other root vegetables

• Berries

• Apples

• Bananas

• Raw honey

3. Avoid Vegetable Oils

You should also significantly limit all refined vegetable oils, including soybean, corn, safflower, sunflower, and canola. 

These oils are predominantly made up of omega-6 polyunsaturated fatty acids (PUFAs), which are highly unstable and oxidize very easily within your body. 

Unfortunately, like gluten, rancid PUFAs are everywhere and hard to avoid. Most commercially-prepared processed foods include them. 

And your thyroid is particularly vulnerable to their effects.

Dr. Raymond Peat, PhD, says that the sudden increase of fragile and rancid polyunsaturated oils into our food supply after World War II has caused many changes in human health, particularly thyroid function and hormones: 

“Their [polyunsaturated oils] best understood effect is their interference with the function of the thyroid gland. Unsaturated oils block thyroid hormone secretion, its movement in the circulatory system, and the response of tissues to the hormone. By 1950, then, it was established that unsaturated fats suppress the metabolic rate, apparently creating hypothyroidism. The more unsaturated the oils are, the more specifically they suppress tissue response to thyroid hormone, and transport of the hormone on the thyroid transport protein. And in 1980, experimenters demonstrated that young rats fed milk containing soy oil incorporated the oil directly into their brain cells, and had structurally abnormal brain cells as a result.”

4. Eat coconut oil

I’ve discussed the brain and mental health benefits of coconut oil before here. 

It can help reduce brain fog and enhance your cognitive performance. And it may be accomplishing this by supporting your thyroid. 

According to Dr. Raymond Peat, coconut oil is very beneficial to the brain and thyroid:

“Coconut oil has a general pro-thyroid action by diluting and displacing anti-thyroid unsaturated oils. And brain tissue is very rich in complex forms of fats. An experiment in which pregnant mice were given diets containing either coconut oil or unsaturated oil showed that brain development was superior in the young mice whose mothers ate coconut oil. Because coconut oil supports thyroid function, and thyroid governs brain development, including myelination, the result might simply reflect the difference between normal and hypothyroid individuals.”

And you don’t need to stick with coconut oil. Coconut milk, water and meat are other ways to get the benefits of coconut. 

5. Try Low-level Laser Therapy (LLLT)

Low-level laser therapy (LLLT) is probably the best cutting-edge way to support your thyroid. I wrote about it previously here.  

Using it on my thyroid has made a remarkable difference in my energy levels and mental clarity. And this is likely because of an increase in my thyroid hormones. 

Multiple studies show that LLLT can improve the production of thyroid hormones and improve thyroid function in patients with chronic autoimmune thyroid disease. Study participants were able to reduce the dosage of their thyroid medication (36, 37).  

A study from Brazil showed that LLLT not only reduced the need for thyroid medication in all patients, but 9 months later after the study concluded, it also showed that 47% of patients no longer required any thyroid medication at all.  Participants with Hashimoto’s thyroiditis also saw a reduction in their anti-thyroid antibodies by more than 39% (40). 

A Russian study also demonstrated a 97% success rate when treating women with subclinical hypothyroidism. Researchers concluded LLLT should be the “method of choice in the treatment of [subclinical hypothyroidism], especially in the elderly” (40). 

Animal research has found similar results in rats and rabbits (38, 39). 

I shine the Optimal 1000 Brain Photobiomodulation Therapy Light (Combo Red/NIR) device on my thyroid. It includes both red and infrared light. I’m convinced most people would benefit from it.

When I’m travelling, I take this smaller and more convenient device with me.

Infrared saunas are another excellent way to expose yourself to infrared light and support thyroid function. Check out my post about the benefits here. 

6. Get Enough Vitamin A and D

Fat soluble vitamins A and D are also critical for optimal thyroid and brain function.

Vitamin D is necessary to help transport thyroid hormone into your cells and deficiency is quite common in people with thyroid problems. Vitamin D deficiency is also associated with thyroid disease and supplementation has been shown to benefit the thyroid. (22-24). 

I previously discussed the brain health benefits of vitamin D here.

You should test and monitor your Vitamin D levels regularly.

Vitamin A helps your body produce thyroid hormone and protects the thyroid gland from oxidative stress (which is higher in people with thyroid issues). Research also shows that vitamin A can reduce your risk of hypothyroidism (19-21). 

However, I personally don’t recommend you supplement with vitamin A. It’s better to get it from food. Pastured eggs, grass-fed liver and butter (or ghee if you can't tolerate butter) are ideal sources. 

Cod liver oil is another great option as it contains both vitamin A, vitamin D and omega-3 fatty acids all together. I take it every so often.

7. Get Enough Minerals

Your thyroid gland needs specific trace minerals to do its job properly. 

I take and recommend a multi-mineral supplement so that you have all the minerals you need to support brain and thyroid health. It includes a small amount of iodine, selenium, magnesium and zinc.

Iodine is the most important, as it’s one of the building blocks used by your thyroid to create hormones. 

However, I don’t recommend supplementing with large doses of iodine separately. Many functional medicine practitioners that I’ve learned from over the years have told me that high iodine intake through supplements can often do more harm than good. Too much supplemental iodine has been shown to cause further thyroid problems (66-68). 

So I think the small amount in a multi-mineral is enough.

And getting some more iodine from whole foods, including seafood and sea vegetables, can also benefit you since they contain other nutrients that can support your thyroid.  

Selenium is another indispensable mineral for your thyroid and brain health.

It helps regulate and recycle your iodine stores, and selenium-based proteins help regulate thyroid hormone synthesis and metabolism.

Without it, you’ll likely experience low-thyroid symptoms.

Brazil nuts are the richest dietary source of selenium. 

Low levels of zinc can also lead to depleted thyroid hormones, and vice versa (34). This is just another reason to supplement with zinc.

As I’ve discussed before, a zinc deficiency can also contribute to stress and anxiety.

And although it isn't mentioned very often, magnesium is also critical for optimal thyroid function. The thyroid gland can't function properly without it (89).

I previously discussed how it can help a lot of people with depression and anxiety here. 

8. Reduce Stress and Cortisol

High levels of physical and mental stress can be detrimental to your thyroid function. 

Your adrenal glands –  two walnut-shaped glands that sit atop the kidneys – secrete your stress stress hormones, such as cortisol, epinephrine and norepinephrine. 

Research shows that cortisol inhibits thyroid hormones from getting into your cells, and weakened adrenal glands can lead to hypothyroid symptoms over time (35).

That’s why it’s critical that you manage stress.

I highly recommend you try to do something every day to manage it. 

The most effective way to significantly and permanently reduce your stress and anxiety is neurofeedback. It’s advanced, guided meditation and I previously wrote about my experience with it here. 

If you can’t access neurofeedback, taking up a daily meditation practice is an excellent idea. 

I’m a big fan of the Muse headband . It can guide your meditation. Similar to neurofeedback, it gives you real-time feedback while you meditate. I wrote an entire review about it here, and you can get it through the Muse website. 

I also find massage, acupuncture, heart-rate variability (HRV) training and an acupressure mat very helpful as well.

Lying on the acupressure mat while using my EmWave2 for just 10 minutes relaxes my entire body and mind. I do this at night before bed. 

Supplements that can help with stress include zinc, ashwagandha and phosphatidylserine, which have been shown to lower cortisol levels (87, 88). 

This anti-anxiety supplement also includes a number of natural compounds that have helped me manage my stress over the years.

Lastly, you should get enough sleep and don’t exercise too much. The stress caused by excessive exercise can wear you’re your body and contribute to thyroid problems. So make sure you get plenty of rest and recover between workout sessions.

9. Take Thyroid-Supporting Herbs

A number of different herbs can assist your thyroid gland. 

Ashwagandha is one of my favourites. Not only can it reduce stress and anxiety, but a number of studies show that it can boost thyroid hormones (25-29).

Bacopa is another adaptogen that has been shown to increase thyroid (T4) hormone levels by 42% (30). 

Forskolin stimulates the release of thyroid hormones (31). 

And one study found that ginseng increases and normalizes thyroid hormone levels (32). 

And last but not least, researchers say that rhodiola can “improve the quality of life of patients with short-term hypothyroidism” (33). 

Rhodiola also has a number of brain and mental health benefits. I explored them previously here. 

I’ve experimented with all of these herbs and they have improved my brain and mental health.

But it’s good to know they have some beneficial effects on my thyroid as well.

10. Eat “Head to Tail”

Whole plant foods tend to be much healthier when they’re left whole, as they tend to have various nutrients that work together synergistically. 

The same can be said about animal food. 

“Muscle meats contain so much tryptophan and cysteine that a pure meat diet can suppress the thyroid. In poor countries, people have generally eaten all parts of the animal, rather than just the muscles – bones, cartilage, skin, organs, and other odd bits. About half of the protein in an animal is collagen, and collagen is deficient in tryptophan and cysteine. This means that, in the whole animal, the amino acid balance is similar to the adult’s requirements.
”

— Dr. Raymond Peat

In other words, muscle meat (chicken breasts, lean beef) shouldn’t be your only source of animal protein. Our ancestors didn’t eat this way, so neither should we.  

Your body and thyroid prefer and expect to receive a balance of amino acids from different parts of whole animals.

That’s why I recommend “head-to-tail eating” – consuming a wide variety of proteins from the entire animal. 

Along with muscle meat, you should regularly cook and eat organ meats such as liver and bone broth.

Bone broth contains collagen, gelatin and amino acids such as glycine and proline that help the body better metabolize muscle meat.

Organ meats such as liver have an abundance of beneficial nutrients that aren’t found in muscle meat alone. For example, it’s much higher in vitamin A, which is important for optimal thyroid health (19, 20). 

I previously discussed the benefits of liver in more depth here.

I personally don’t like the taste of liver and bone broth can be inconvenient to make all the time, so I often supplement with grass-fed beef liver capsules and drink high-quality pre-made bone broth.

I also take a Multi-Glandular For Men, which contains a number of different organ tissues. There is also one for women. 

But if you’re actually interested in learning about how to cook and incorporate more whole animal proteins into your diet, I recommend checking out the book Odd Bits: How to Cook the Rest of the Animal by Jennifer McLagan.

11. Limit Halogens

Your thyroid doesn’t know the difference between iodine, and other halogens such as bromine, fluorine, chlorine, and perchlorate, which are often found in tap water. 

So your thyroid soaks them up and uses them like iodine.

By occupying iodine receptors, they worsen iodine deficiency, inhibit the production of your thyroid hormones and contribute to thyroid dysfunction.

Studies show that chlorine interferes with proper conversion of thyroid hormone (50, 58-61). 

That’s why I recommend filtering your drinking and shower water. Brita filters aren't enough because they don’t remove fluoride. I use this water filter to make sure I’m drinking the purest water available. It filters everything out of the water. I also use this filter to remove chlorine from my shower water. 

The research shows that bromide in particular can cause a lot of problems. Bromide is found in pesticides, prescription medication, plastic products and personal care products. PBDE (bromide) fire retardants have been added to mattresses, carpeting, electronics, furniture and car interiors since the 1970s. 

Even small amounts of bromide can be problematic, depleting iodine and weakening the thyroid gland. Bromide levels are 50 times higher in thyroid cancer than normal thyroid tissue, and elevated levels of bromide have been linked to mental illness, including depression and schizophrenia (50-57). 

12. Avoid Environmental and Dietary Mycotoxins

Mycotoxins – toxic metabolites produced by mold – can also disrupt normal thyroid function.

Mycotoxins are released into the air in water-damaged buildings, and you may not realize it’s affecting your brain and thyroid health until you develop certain symptoms. And even then, people frequently won’t make the connection between the mold and their health. 

That’s what happened to me, and my hormonal health went downhill, along with my brain and mental health. Luckily I’ve recovered since then. 

Mycotoxins are known hormone disruptors that cause inflammation, and a couple of studies mention that there is an increased frequency of “thyroid, immune dysfunction and autoimmune conditions” in people exposed to water-damaged building (41, 42). 

And one study shows that mold exposure is correlated with hypothyroidism and Hashimoto’s thyroiditis (43). 

Kurt and Lee Ann Billings wrote the book Mold: The War Within after extensive personal bouts with toxic mold exposure. They write extensively about their experience and recovery and describe ongoing problems with thyroid dysfunction. 

After I moved out of the moldy home, I became extremely sensitive to any environmental mold and mycotoxins. 

I now use an air filter in my apartment. It removes any mold spores and smoke that may be in the air.

Low amounts of mycotoxins are often found in some seemingly healthy foods, such as tea, nuts, grains, coffee and chocolate. I recommend finding the freshest, highest-quality, organic versions of these foods.

Lastly, if exposed to mold or their toxins, you should supplement with activated charcoal or bentonite clay.

Activated charcoal and bentonite clay are potent natural treatments that can trap toxins and chemicals, allowing them to be flushed out of your body.

13. Avoid and Remove Other Environmental Toxins

Mold and other halogens aren’t the only endocrine disruptors in your environment that can affect your thyroid metabolism and function.

In the book Thyroid Mind Power, Dr. Karilee Shames reports that “the last 40 years have witnessed a massive increase in the amount of hormone-disrupting synthetic chemicals, finding their way into our air, food and water. The most sensitive and highly susceptible of human tissues turned out to be the thyroid gland.”

Here are some common ones:

• Bisphenol A – found in plastic bottles and containers. I recommend you only eat and drink out of glass, ceramic and stainless steel. Avoid storing any of your food in plastic too. BPA-free plastic isn’t much better for you and can still disrupt hormonal health.

• Perfluorooctanoic acid (PFOA) – found in common household products including non-stick cookware and waterproof fabrics. Researchers have found that people with higher levels of PFOA (perfluorooctanoic acid) have a higher incidence of thyroid disease (44, 45).

• Other pesticides and chemical additives – You should avoid processed food and eat organic as often as possible, wash all produce thoroughly to minimize your pesticide exposure, and find personal care products that don’t include toxic chemicals.

I also recommend increasing your levels of glutathione – your body’s main antioxidant and master detoxifier – to help your body combat the above substances from your body. I do this by supplementing with glutathione on regular basis. 

Or you could take NAC and Vitamin C to help your body produce more of its own glutathione. 

Researchers have found that a decrease in thyroid function could be reversed by NAC supplementation, which increased glutathione. This is because glutathione plays a key role in the production and conversion of your thyroid hormones (46-49). 

Epsom salt baths, infrared saunas, and turmeric can also help your body release and remove environmental toxins. 

Summary and Conclusion

With the right information, you can make simple choices to improve thyroid health.

Here's a summary of everything we've gone over:

• Cut out gluten-containing grains (barley, wheat, rye, spelt)

• Don't follow a long-term ketogenic low-carb diet and eat enough calories and healthy sources of carbohydrates. See my free food guide for plenty of options. And consider taking exogenous ketones to get the cognitive benefits of a ketogenic diet without actually having to follow the diet.

• Avoid refined vegetable oils, including soybean, corn, safflower, sunflower, and canola

• Eat coconut oil

• Try low-level laser therapy (LLLT)

• Supplement with Vitamin D, and make sure you get enough Vitamin A from egg yolks, grass-fed liver and ghee

• Take a multimineral with iodine, selenium and zinc

• Reduce stress with deep sleep, massage, acupuncture, meditation, neurofeedback, the Muse headband, an acupressure mat, the EmWave2, ashwagandha and phosphatidylserine

• Take herbs such as bacopa, ginseng, forskolin and rhodiola

• Eat beef liver and bone broth

• Filter your drinking water with a filtration system to avoid fluoride, chlorine and other halogens

• Avoid mold, mycotoxins and other environmental toxins, and protect yourself from them with an air filter, activated charcoal and glutathione

So with that, I want to leave you with a quote from a book I read recently by Sam Harris, called Free Will.

I think this quote is appropriate considering the wide variety of factors that underlie brain and mental health problems:

“Becoming sensitive to the background causes of one’s thoughts and feelings can - paradoxically - allow for greater creative control over one’s life. It is one thing to bicker with your wife because you are in a bad mood; it is another to realize that your mood and behaviour have been caused by low blood sugar. This understanding reveals you to be a biochemical puppet, of course, but it also allows you to grab hold of one of your strings: A bite of food may be all your personality requires. Getting behind our conscious thoughts and feelings can allow us to steer a more intelligent course through our lives (while knowing, of course, that we are ultimately being steered).”

So even though it seems like there are an overwhelming amount of “strings” to pull, realize that you don’t have to pull them all at once.

You just have to start with one, and go from there.

And then over time, you'll start to get a handle on all of them, and you'll heal.
