Your blood-brain barrier (BBB) is a layer of very selective cells that allows certain molecules and nutrients from your blood to reach the brain.<\/span> When the BBB is leaky, it can allow inflammatory proteins and harmful substances to pass through. As a result, a leaky brain may contribute to neurodegeneration and neuroinflammation, causing brain fog, low mood, and more.<\/span> <\/p>\n\n\n\n

Therefore, if your goal is to perform at your best cognitively, you want to optimize your BBB health. To learn more about the BBB and factors that can compromise it, check out part 1<\/a> of this article.<\/p>\n\n\n\n

In this article, part 2, we\u2019ll cover how to measure your blood-brain barrier, along with ways to repair it.<\/p>\n\n\n\n

How To Measure Barrier Permeability<\/h2>\n\n\n\n
\"magnifying<\/figure>\n\n\n\n

Aside from symptoms of a leaky BBB, many biohackers are interested in testing or quantifying numbers that matter. The following tests allow you to screen for a leaky BBB or to determine the overall risk of increased BBB permeability:<\/p>\n\n\n\n

1.  Matrix metallopeptidase 9 (MMP9) levels<\/strong>– The enzyme MMP9 degrades the protective barrier.<\/span> An MMP9 blood test can help determine the health of your BBB. <\/p>\n\n\n\n

2. Homocysteine levels<\/strong>– High levels of this toxin can increase BBB permeability.<\/span> Therefore, homocysteine levels may reflect the integrity of your BBB. <\/p>\n\n\n\n

3. Spectroscopy<\/strong>– Evan\u2019s blue dye can bind a protein (albumin) that won\u2019t cross the BBB under healthy conditions but can cross a compromised BBB. The amount of dye that crosses your BBB can determine the level of permeability.<\/span> However, since this method is somewhat invasive, you may only see it in research settings.<\/p>\n\n\n\n

How To Repair A Leaky BBB Naturally: Lifestyle Changes, Food, And Supplements<\/h2>\n\n\n\n

Repairing the BBB involves both dietary and lifestyle changes that support and improve brain health. To maximize nutrient transport into the brain and restore your BBB integrity, consider some of the following supplements and steps:<\/p>\n\n\n\n

Heal Your Leaky Gut<\/h3>\n\n\n\n

A leaky gut may very well lead to a leaky brain. Both your brain and intestinal barrier rely on tight junctions that provide the seal between cells.<\/span> A leaky gut is similar to a leaky brain, where this seal is loosened. Intestinal permeability exposes the gut content, such as partially digested foods and bacteria parts, to the immune system. This can lead to chronic inflammation that opens up the BBB.<\/span><\/p>\n\n\n\n

Gluten is a common cause of both leaky gut and leaky brain as it can open up tight junctions by increasing a protein called zonulin, even in non-celiacs.<\/span><\/span> Zonulin regulates both intestinal and BBB permeability partly by controlling the tight junctions.<\/span><\/span> Increased zonulin levels are correlated with increased BBB degradation.<\/span><\/span> <\/p>\n\n\n\n

\"Gluten<\/figure>\n\n\n\n

To maintain a healthy gut barrier, you want to keep your gut healthy and support your gut flora. Gut flora growth and diversity is key for brain health and BBB integrity. <\/p>\n\n\n\n

In mice, the lack of gut bacteria correlates with increased BBB permeability.<\/span> Introducing bacteria or beneficial bacterial metabolites such as butyrate reduces their BBB permeability, supporting the link between a healthy gut and healthy brain.<\/span><\/span> To support a healthy gut flora, consider supplementing with a probiotic\/prebiotic duo like this one<\/a>.<\/p>\n\n\n\n

Work with a naturopathic or functional medicine doctor to address your compromised intestinal barrier. To learn more about leaky gut and how to fix it, check out this leaky gut article<\/a>.<\/p>\n\n\n\n

Avoid Alcohol, Or Have It Sparingly<\/h3>\n\n\n\n

Alcohol is generally bad for the brain as it\u2019s a neurotoxin. Upon alcohol exposure, highly active enzymes involved in the metabolism process are found at the BBB.<\/span> Alcohol metabolism also produces substances that can cause damage to the barrier.<\/span> This damage activates MMP9, further injuring the BBB.<\/span><\/p>\n\n\n\n

The human brain depends on glucose as an energy source and healthy brain function.<\/span> Alcohol intake reduces glucose transport across the barrier and into the brain, affecting neuronal health.<\/span><\/span> <\/p>\n\n\n\n

Alcohol consumption can also cause vitamin deficiencies, possibly due to reasons like impaired absorption in the intestinal tract.<\/span><\/span> It is linked to a vitamin B1 deficiency, which can cause barrier dysfunction.<\/span><\/span><\/span><\/span><\/p>\n\n\n\n

For optimal BBB health, limit your consumption of alcohol and opt for a non-alcoholic drink instead.<\/p>\n\n\n\n

Manage Any Stress In Your Life<\/h3>\n\n\n\n

Stress can affect BBB permeability in mood-controlling brain regions in mice, and subsequently alter their behavior.<\/span> Chronic social stress can alter barrier formation by reducing structural proteins that make up the BBB.<\/span><\/p>\n\n\n\n

Stress can also cause brain inflammation, partly by opening the BBB and allowing the inflammatory molecules through.<\/span> <\/p>\n\n\n\n

There are some general steps everyone can take to ease stress and maintain their brain health. You can find great tips to manage stress here<\/a>.<\/p>\n\n\n\n

Reduce Mold Exposure In Your Environment<\/h3>\n\n\n\n
\"Side<\/figure>\n\n\n\n

Mold exposure is a serious problem for many people, especially with chronic exposure (unknowingly) to mold in homes or workspaces. Mycotoxins (produced by mold or fungi) are sometimes present in food sources such as tea and nuts.<\/span><\/span> <\/p>\n\n\n\n

Mold can release mycotoxins into the air, which may affect your brain and cognitive function. This is possible because mycotoxins can compromise the mitochondria (cell energy generators) and disrupt barrier function.<\/span> Mycotoxins also disrupt BBB integrity and cause cell toxicity.<\/span> <\/p>\n\n\n\n

If you suspect that mold toxins could be interfering with your brain function, consider getting a professional inspection for your home or location that you\u2019re exposed to. Also, see a naturopathic doctor to test and detox from mold. <\/p>\n\n\n\n

Improve Your Sleep Time And Quality<\/h3>\n\n\n\n

Circadian rhythms and sleep regulate BBB permeability.<\/span> So, sleep deprivation and poor sleep quality may affect your BBB health.<\/p>\n\n\n\n

In mice, six days of sleep restriction impaired their REM sleep (high energy dream-state) and BBB function.<\/span> The researchers measured the animal\u2019s BBB permeability with a fluorescent tracer. Once the mice got some adequate rest, their healthy BBB function came back. A similar study confirmed this sleep recovery result and that REM sleep is important for BBB structure and function.<\/span><\/p>\n\n\n\n

Sleep loss can also cause inflammation, which disrupts the BBB.<\/span> Therefore, you want to get adequate high-quality sleep every night for a healthy blood-brain barrier.<\/p>\n\n\n\n

Have More Magnesium <\/h3>\n\n\n\n

High magnesium intake can reduce BBB permeability and help regulate BBB function.<\/span> Magnesium protects the BBB in many animal models of brain conditions and injuries, suggesting that it may also support human BBB during day-to-day insults and stress.<\/span><\/span><\/p>\n\n\n\n

Magnesium also plays an important role in neurological health, and it actively crosses into the brain via the BBB.<\/span><\/span><\/p>\n\n\n\n

To increase your intake of magnesium, natural foods are a quick way to do so. Check out this article<\/a> for a list of magnesium-rich foods. Also, consider supplementing with Magnesium Breakthrough<\/a> to ensure healthy magnesium levels in your body.<\/p>\n\n\n\n

Add Some Berberine<\/h3>\n\n\n\n

Berberine is a bitter chemical found in plants such as Oregon grape and goldenseal.<\/span> It can easily cross into the brain via the BBB, and is neuroprotective.<\/span> Berberine can protect BBB structure by increasing claudin-5, a protein involved in BBB permeability.<\/span><\/span> <\/p>\n\n\n\n

Increase Your Daily Amount Of B Vitamins<\/h3>\n\n\n\n

High levels of the toxic amino acid homocysteine <\/em>compromises the BBB.<\/span> High homocysteine is linked to B vitamin deficiencies, as these vitamins are required to break it down.<\/span><\/span> Vitamins B6, B9, and B12 are the most essential to decrease homocysteine, although other B vitamins are indirectly involved in homocysteine metabolism.<\/span> <\/p>\n\n\n\n

\"<\/figure>\n\n\n\n

Researchers evaluated the effect of a high-dose combination supplement of B6-B9-B12 in 30 participants with high homocysteine levels.<\/span> Along with homocysteine they measured albumin levels following treatment, as this protein does not cross the BBB under healthy conditions. Both homocysteine and albumin levels decreased following supplementation, suggesting that the B vitamins may restore BBB integrity.<\/span> <\/p>\n\n\n\n

B vitamins are essential to healthy brain function, and they all work together.<\/span> This is one of the reasons Nootopia products include B complex. Speak to your doctor if you wish to check your homocysteine and levels of your vitamins B9 and B19.<\/p>\n\n\n\n

You can supplement with vitamin B complex if you are looking to increase your intake. Liver, fish, poultry, and leafy greens are also all great sources of this vitamin, which can help you maintain the health and function of your BBB.<\/p>\n\n\n\n

Supplement With Acetyl-L-carnitine (ALCAR)<\/h3>\n\n\n\n

ALCAR is a form of carnitine that our body naturally produces and can easily cross the BBB.<\/span> It is neuroprotective<\/span>, and several animal studies show that ALCAR can:<\/p>\n\n\n\n
