Is Your Brain Making Enough GABA?

GABA (Gamma-AminoButyric Acid) is an inhibitory neurotransmitter that has a calming and relaxing effect in the brain.  It acts like the brakes in a car, to where it slows down and/or stops brain activity on an as-needed basis to help us function better.

When we are low in this neurotransmitter, our brain continues to hit the gas, overstimulating us with activity.  Our gut microbiome plays an important role with GABA production and helps to convert glutamine and glutamic acid into GABA.  A disordered microbiome is a major cause of low GABA production (1, 2).


GABA’s Activity in the Brain

GABA receptors are spread out throughout the brain and they are ligand-activated chloride channels that when activated, allow the negatively charged chloride ions across the cell membrane and into the cell where they reduce cellular activity.  In addition, they help to shunt the positive charged potassium ions across the cell membrane and out of the cell in order to inhibit activity and take the nervous system away from threshold.

GABA is synthesized from the amino acid glutamate with the enzyme glutamate decarboxylase (GAD) and pyridoxal phosphate (which is the activated form of vitamin B6) as the key cofactor.  This process converts glutamate, which is the principle excitatory neurotransmitter in the brain, to the principle inhibitory neurotransmitter GABA (3, 4).

In most regions of the brain, GABA is too large a molecule to cross the blood brain barrier (BBB) (5).  However, there are certain areas that have a permeable barrier, such as the periventricular nucleus of the hypothalamus, which sits in the 3rd ventricle of the brain.  GABA has been shown to influence brain activity through this region and help to modulate the amount of human growth hormone release (6).

GABA is also an important part of the synthesis of the sleep hormone melatonin.  It has a key role in the conversion of serotonin into N-Acetylserotonin, which then converts to melatonin for inducing sleep (7).  Melatonin also plays a huge role in the body’s immune function.

Symptoms of Low GABA Levels


People with low levels will often see a worsening of these symptoms when they skip a meal or attempt to fast.

Factors Involved In Reducing GABA Levels

There are too many factors involved in reducing GABA levels to name.  Here are some of the most common.

Reducing GABA

Chronic Stress and Adrenal Fatigue

Chronic stress will increase the levels of cortisol, norepinephrine and epinephrine in the brain and body.  This also shunts the body into producing more excitatory glutamate and reduces GABA production (8).

Too much glutamate in the brain causes over-excitation of the brain cells.  In addition, the increase in stress hormones ramps up cellular activity and causes excessive production of free radicals which damage brain cells and further reduce normal GABA production (9).

Overtime, when an individual is in a long-term, highly stressful condition, they rewire their brain cells and have a functional deficit in GABA production (10).  This is where lifestyle intervention and GABA supplementation strategies done over a period of time, are so helpful in rewiring the brain to produce and use GABA effectively again.

Inadequate or Ineffective Sleep

Lack of quality sleep is a chronic stressor on the body and increases stress hormone production.  This causes the same mechanisms as what was described right above.  The question is, what came first, was it stress and low GABA and melatonin that caused the poor sleep or was it the poor sleep that caused chronic stress and low GABA and melatonin.

In either case, it is a true vicious cycle where several poor nights of sleep in a row can lead to a rewiring in the brain and a functional deficit in GABA production (11).  This is another case where using lifestyle intervention and supplementation strategies over a period of time is so extremely helpful for rewiring the brain to produce and use GABA effectively again.

Poor Blood Sugar Stability

Blood sugar dysregulation is a significant stressor in the brain and disrupts the Blood Brain barrier, which is designed to protect the brain from oxidative stress, infectious microbes, toxic debris and chronic inflammation.

Hypoglycemia or low blood sugar causes a partial starvation of the brain tissue, which increases stress hormones and opens up the BBB for more nutrients to cross over.  This also allows more toxins and free radicals to effect brain tissue causing elevated stress hormones and glutamate release.

Additionally, high blood sugar causes insulin resistance in the brain and a functional starvation where there is enough glucose but we cannot get it into the brain to be used.  In this case, it leads to opening the BBB and excessive oxidative damage to the brain with elevated stress hormones and glutamate release.


Gut Microbiome Dysbiosis  

There is a growing body of research linking the gut microbiome to neurological health.  Research has shown that breakdown of the intestinal lining along with low levels of good microbial inhabitants such as lactobacillus and Bifidobacterium are linked with lower GABA levels, increased brain excitability and neurological inflammation (12).

These microbes are essential for B6 absorbtion and activation, which is the critical cofactor in the conversion from the excitatory neurotransmitter glutamate into GABA.  Without adequate activated B6, we end up with glutamate excitotoxicity and increased risk of anxiety, seizures, depression, dementia and Alzheimer’s (13, 14).

GAD Antibodies

In an earlier section we discussed how the body converts glutamine to GABA using the glutamic acid decarboxylase enzyme and the activated form of vitamin B6.  Some individuals have elevated antibodies (autoimmunity) to the GAD enzyme.  This is especially common in individuals with epilepsy and other seizure disorders (15).

Other research has found this condition in individuals with cerebellar ataxia, stiff man syndrome, type I diabetes, drug-resistant epilepsy, balance problems and more (16).  In these cases, following protocols to reduce inflammation and autoimmunity are especially helpful.  In addition, these individuals may need large doses of supplemental GABA.


Low Zinc, Vitamin B6, Magnesium, Taurine & Glutamine 

The amino acid L-glutamine is the most abundant amino acid in the body and it is the precursor to GABA production.  Glutamine is first converted to glutamic acid or glutamate, which is key for a good attention span, brain energy, learning ability and memory.

This is important but we need an even percentage of the glutamic acid to then be converted into GABA or we risk over exciting our neuronal cells.  The next step in converting glutamate to GABA is dependent upon the activated form of vitamin B6 (pyridoxal-5-phosphate P5P).

Additionally, the amino acid taurine increases the communication and productivity of P5P and promotes the production of GABA.  There are studies that have shown that a deficiency of taurine can result in anxiety (17).

Zinc enhances the release of GABA by working to help activate P5P and stimulate the activity of GAD (18).  Both B6 and zinc are also essential to the production and utilization of other neurotransmitters such as serotonin, dopamine, norepinephrine, epinephrine and histamine.

Magnesium is important for binding and activating GABA receptors.  Without adequate magnesium, we are unable to effectively activate GABA receptors and utilize it effectively (19).  Magnesium deficiency is extremely common with over 80% of women and 70% of men suffering with this and thus supplementation for most will dramatically impact GABA activity.


Testing For GABA Deficiency

The way that I and many functional health practitioners look at GABA levels is through symptom questionnaire’s and an organic acid test.  If a client is demonstrating many of the symptoms listed above that are associated with low GABA than the organic acid test would be warranted.

The organic acid test is a urine test that will look at a biomarker of B6 called pyrodixic.  Low levels can indicate that their isn’t enough B6 to successfully convert glutamate to GABA.  We may also see very high or very low levels of homovanillic (HVA), which is a dopamine biomarker and vanillymandelic (VMA), a biomarker of adrenaline.

When these are very high it is a sign of heightened stress hormone production which would favor the production of glutamate over GABA.  When these levels are very low, it may indicate an overwelmed hypothalamic-pituitary – adrenal axis.  You can find the organic acid test here

Strategies to Raise GABA:

In order for the body to manufacture GABA, there needs to be an abundant amount of the amino acid L-glutamine present.  Glutamine is then converted into another amino acid called glutamic acid and then into GABA.

This whole process depends upon the activity of zinc, vitamin B6 and taurine.  If we are deficient in these nutrients we will not be able to produce adequate amounts of GABA.

  1. Adapt to Stress Better: Follow the 25 lifestyle strategies in this article to help adapt to stress better and heal any form of adrenal fatigue you may be suffering with.
  1. Anti-Inflammatory Diet: Be sure to follow the an anti-inflammatory nutrition plan using real and organic foods in order to provide the right nutrients to support healthy neurotransmitter function.
  1. Sleep Better: It is key for you to prioritize sleep if you are going to improve your GABA levels.  Follow the strategies in this article to help you sleep better.
  1. Improve the Microbiome: Consume fermented foods, anti-microbial and carminitive herbs such as garlic, onions, oregano, basil, thyme, peppermint, ginger, etc. to help improve the overall constitution of the gut microbes.
  1. Take Epsom Salt Baths with Essential Oils: Epsom salt baths can provide magnesium into the blood stream that acts to relax the body.   Adding in essential oils such as valerian, kava, chamomile, lavender, lemon balm and passionflower can be extremely supportive for healthy GABA levels.
  1. Deep Breathing: Taking time to focus on breathing can be very supportive for GABA levels.  Try taking 3 minutes every hour and focus on doing deep breathing with a 5-10 second inhalation and a 5-10 second exhalation.  Read this article for more info on breathing properly.
  1. Regular Exercise: Regular movement is good for all neurotransmitters.  Individuals with low GABA should be doing low-intensity movement such as walking and doing lots of deep breathing.  Practicing yoga can be extremely supportive of GABA levels.

Best Foods to Boost GABA Levels:

Healthy microbes such as lactobacillus strains produce GABA naturally as a byproduct of metabolizing the amino acids L-glutamine and glutamic acid.  Fermented foods that are rich in these lactobacillus microbes are rich in GABA.  They are truly the only dietary source of GABA.  You may see other lists online, but those are foods that are richer in

  1. Sauerkraut
  2. Kimchii
  3. Grass-fed cow or goat kefir or yogurt
  4. Coconut Water Kefir
  5. Beet Kvass
  6. Coconut milk yogurt
  7. Kombucha
  8. Pickles
  9. Pickled Ginger
  10. Miso, Natto or Tempeh


Supplements to Raise GABA Levels:


Magnesium:  Supplemental magnesium helps to raise GABA levels.  By far, the most effective form for this is called Magnesium L-threonate.  I recommend doing 1-2 grams – 1-2 times daily.

B Complex:  B6 deficiencies can cause low levels of GABA.  I will typically recommend a full B complex supplement with activated forms of B vitamins to maintain.

Probiotics:  In particular, supplementing with probiotics that contain a variety of lactobacillus and Bifidobacterium strains help to raise up GABA levels.   I recommend taking 30-100 billion CFU’s daily.

GABA:  Taking supplemental GABA can be very effective.  It is thought to be too large to cross the blood brain barrier, however, most people with low levels have a disrupted BBB and respond very well to supplemental GABA.  I recommend doing 100-200 mg 1-2x daily.

L-Glutamine:  Supplementing with L-glutamine can be very effective for supporting GABA levels.  I recommend starting with 4-5 grams to see how your body is tolerating it and gradually going up to 10-12 grams.

If you notice an increase in irritability, headaches or anxiety, you may be deficient in B6 and/or zinc.  Try adding those in while reducing L-glutamine levels for a while and then try L-glutamine again.

Taurine:  This is an amino acid precursor to GABA and has a similar structure but is smaller.  In the brain, it helps to activate GABA receptors.  I use 300-600mg, 1-2 times daily.

L-Theanine:  is a naturally occurring, biologically active, free-form amino acid that provides relaxation support.  L-theanine improves GABA production and induces a state of relaxation of the mind without inducing drowsiness.  I recommend 50-100 mg, 1-2 times daily.

Valerian, Kava, Chamomile, Lavender, Lemon Balm & PassionFlower:  These herbs help to improve GABA production and utilization in the brain.  You can drink herbal teas with these or use the essential oils on your body, in an Epsom Salt bath and in a diffuser so you can breathe in these supportive compounds.

Dr Jockers Strategy:

I follow a number of the strategies, including healing the gut, balancing blood sugar and reducing stress.  My main supplements I use to improve GABA levels are Brain Calm magnesium and Mood protect.  Yes, you can take these both together without any problems.

Brain Calm Magnesium:  This is a specific form of magnesium is the only form of magnesium proven in animal studies to cross the blood-brain barrier. Boosting the brain’s magnesium level is vital to healthy cognition, which includes long- and short-term memory, learning, stress management and sleep.

Normal Dosage:  1 scoop – 1x daily             Advanced Dosage:  2 scoop – 2-3x daily


Mood Protect:  Combination of herbs, nutrients and compounds that promote serotonin and GABA production to ease anxiety and improve overall mood and sleep.  This product has clinical dosages of GABA, taurine, L-theanine and 5-HTP.  This also contains small amounts of zinc, B6 and magnesium to improve natural GABA production.

Normal Dosage:    Take 1 cap – 2 times daily (away from meals)

Advanced Dosage:   Take 2 caps – 2 times daily (away from meals)

  1. I’m recovering from a shingles that went to my arm that has lymphodema . I have had cancer, chemo, mastectomy , that took 12 lymph modes. Also had 26!rpunfs of radiation and then had to have total knee replacement . All of this in 1 1/2 years and now this. The pain in my arm and the lose of being able to use it has been unreal for me. I have been taking GABA , the supplement for 2 years my doctor just prescribed the prescription. I take magnisium. B complex , a probiotic. I have been off work 6 weeks and going to therapy, but get really down because it’s hard to do things , I pray that the burning pain will stop!

  2. Excellent article – thanks! Recovering from Restless Leg Syndrome (iron supplementation has reduced severe symptoms to zero), but insomnia remains. Magnesium – in EVERY form is excitable to me – even taking it in the AM. Mostly when I awake at 3AM – taking an ibuprofen (a glutamate blocker) let’s me fall asleep ’till 6AM or so. I take a lot of anti-inflammation supplements and B-vitamin daily, probiotics, fiber and fermented veggies also daily. Can’t figure it out!

    1. So sorry to hear about this Richard! Could be a glutamate conversion issue, a ketogenic diet may be helpful. You may also benefit from getting some functional lab work done to see what is really going on. You can email if you are wanting to work with someone on this!

  3. Hi, my Formiminoglutamate levels tested high (OAT test) and they recommended Folate so that it can convert to glutamate. If I’m taking glutamine and don’t have enough Folate, is that why my Formiminoglutamate levels are high? Am I not going to make much Gaba until I take Folate? I don’t have MTHFR. I was previously taking 5g of Glutamine fo a couple of months before taking the OAT test. I stopped taking it several weeks ago for another reason. Glutamine does seem to have a bit of a calming feeling when I take it but maybe it’s just helping my gut that has issues. Oh and I might have one GAD SNP. Thank you for any insight.

  4. I have a question about overstimulation. Can it be that glutamine protects the brain from the cause of a burn-out? My doctor says that glutamine has not an direct effect to stabilize overstimulation. The glutamine has only the relaxing side-effect. Thank you in advance!

    1. Hey Michael, it is actually GABA that has this protective effect as too much glutamate can become harmful to the brain. A very stressed person can still convert excess glutamine into glutamate, the key is to support the conversion of glutamate into GABA using magnesium and B vitamins.

  5. Hi
    I have Stiff Person Syndrome and this is the best article I have read regarding GABA and GAD. I have even used a very similar way to describe it to others as this article does using a car as an example. I find stress counterproductive to what I do take for this condition. I also have ivig every 8 weeks.
    Are there any supplements that I could take to increase GABA, decrease anti GAD antibodies and help me sleep?

  6. I forgot to mention that I get serotonin syndrome so I cannot take SSRI. Would 5-HTP increase serotonin to harmful levels?

  7. I believe genetics also factor in. I have 3 mutations on GAD1 which all reduce my production of the enzyme. I have a very active mind and when under prolonged stress a tendency towards anxiety and panic attacks.

    I noticed the foods you recommend are also generally high histamine and are the same foods I am drawn to. I wonder if there is some connection between histamine and GABA. My craving for high histamine foods perhaps means compensating for low GABA with Histamine?

    It is interesting to note that GABA is also produced in the Pancreas and has some relationship to blood glucose levels, insulin, and glucagon altho this is not yet well understood. I have had occasional low blood sugar.

    I’ve just started trying GABA and I get a bit of a rush feeling from it for a few minutes. I tried 1500 mg and have just started doing that daily. I went from feeling like I was dragging around, unmotivated, low energy and focus to feeling wonderful, high energy, and motivated practically overnight (including a great night’s sleep). I have been doing a low carb diet as well but recently started have some cravings for carbs – and the GABA just entirely stopped that too. I notice the higher mood lasts maybe a hour or so but the general well being lasts longer.

    I have tried the precursors in the past without much luck probably as I don’t make enough of the enzyme to utilize them and I do find that glutamine supplementation is helpful.

    I was thinking to try spreading out over the course of a day in smaller doses and also start to reduce slowly from 1500mg until I find a good balance point. While the 1500mg did pull me out of the funk it also changed my sleep cycle. I tend to stay up late, too late, and not feel like going to bed. Now, day 2 of GABA and it is early evening and I’m yawning!

  8. Dear Dr.
    I am a man 49 years old. 63kgs.
    Suffering from GERD for two years everyday. Not severe but several times a day.
    Anxiety, to worry about things too much, etc. increases it. Relaxing, walking and similar syntoms reliefs. Many times difficulties to work concentrated as I am always reevaluating my status regarding GERD.

    I have been taken benzos (not now) and it reliefs. Acid inhibitors do not help.

    Gaba resulted for some weeks but the problem appeared again.

    All kind of herbs also tried. Valerian root has good effect strenghing esopagous esfinter and it makes good for me.

    Mg and B vitamins no effect. Theanine no effect. Zn carnosine no effect. Probiotics no effect. Diet no effect. Endoscopy was ok. Blood tests for gluten intolerance were ok. White tongue in the morning and during the day.

    My question: is glutamine a good option to try? What about taurine? Sorry for my bad English (from Spain)

  9. Dear Dr Jockers, thank you for the great article. What do you know about gene mutations affecting levels of GABA? From my 23 and Me results I came to find out that 7 of the 10 SNP’s tested are homozygous. I have always suffered from anxiety and never knew why, now I have an idea why. I know epigenetics play an important role in health but are these polymorphisms too much for my body to handle?

    Thanks for your work

  10. Hello Dr. Jockers,

    I do gaba receptors and producing gaba go hand and hand?

    I am worried i fried my gaba receptors using Benzo’s, and i need a way to repair my brain to its old functionality which was completely fine. Now i have regular anxiety and a sense of worry hanging over me at most times during the day. I understand the brain is capable of repairing it self, however i am worried as this has gone on for around 3 months following the benzo use. some weeks where my stress and anxiety are very high and other weeks where they are practically non existant.

    Please get back to me soon as i am very stressed about the current situation.

    1. Hey RA, following the strategies in this article should help restore both production and receptor sensitivity with time. Sorry to hear about these long lasting effects of your medication!

  11. GABA is extremely overrated and I think researchers have it completely backwards in a couple of phenomena. Excitation and inhibition in the brain are rarely global, unless it involves consciousness itself, and the numbing effect of GABA is one that “traps” one, more than just a “relaxing” one, and can increase motor activity in other parts of the brain I have found.

    I have Akathisia and GABA is known to me by my layman’s research of possible ways of treatment, and I have also tried it again and again (and felt it clearly), and contrary to an inhibition of involuntary movement it has exactly an opposite effect to motor activity and beyond that a kind of psychological “compulsiveness”, where one can’t easily change one’s current activity, resulting from that “trapping” numbness. The “numbing” is also known from, and might be related to, other treatments by SSRIs.

    The funny thing is, equating “inhibiting” with relaxing here is where “researchers” fall into a naive trap of false similarity, and perhaps arrogant condescension towards patients’ symptoms (in the case of neurologists mostly self-cause..). Akathisia is a prime example of showing that not all effects on the brain, perhaps most famously “relaxing”, are global or affect all areas or layers. Sure you can make one sleepy, but you won’t treat the “root” cause, won’t even touch it. (Also known in such simple things as breathing etc.)

    And there is a mechanism behind it too: apparently GABA increases acetylcholine in the striatum, which is known to cause motor-over-excitation (!) and exactly what causes akathisia (and diverse Parkinson-likes) in the first place.

    Damage to the opposing “excitatory” Glutamatate receptors on the other hand is believed to be a reason for many side-effects from taking SSRIs. And also from drinking alcohol by the way (!), because it is a GABA-analog. I haven’t tried anything to assist or “repair” the Glutamate receptors yet, if it would even work, but I bet GABA is if anything the false path to follow, and I bet researchers in many cases have it completely backwards because of a naive similarity which doesn’t apply to how the brain works at all.

    And again, I have tried GABA repeatedly, and it doesn’t affect the relevant areas at all, but only seems to make them worse, and generally causes a kind of “entrapment” in the head and brain fog.

    1. It is because GABA supplement worsen glutamate.
      GABA itself can be converted back into glutamine, which is then converted back into glutamate through a metabolic pathway called the GABA shunt. So GABA supplementation can end up increasing glutamate in some people as well.
      read the whole thing here.

      ketogenic diet could help you. I suffere from internal akathisia and keto diet keeps it at bay. Also google BCP 157 peptide. It regenerates intestines, nerves, joint, brain and more./

  12. Thank you for your very informative article.
    I am one of a very rare group of people… those who have suffered from metronidazole (Flaygl) toxicity. On very rare occasions Flagyl or it’s metabolites cross the blood brain barrier resulting in neuro-toxicity, leading to such symptoms as peripheral neuropathy, headaches, extreme fatigue, gastro intestinal issues, depression, anxiety, heart palpitations, muscle wasting, etc. I have read that Flagyl and/or it’s metabolites mimic thiamine, and disrupt the GABA system. Many who have suffered from metronidazole toxicity have seen dramatics improvements with the use of thiamine and magnesium suppliments. However, those with muscle wasting have not seen improvements. Do you have any experience treating toxicity caused by medications? And would you recommend that a person suffering from muscle wasting take an L glutamine suppliment?

  13. A very thorough and well researched article thanks so much Dr. Jocker.

    Quick question if you don’t mind. I have lyme disease which somehow is the root cause of my nerves to flare up all over my body. It’s quite unbearable and flares throughout the day. Gabapentin calms it down but doesn’t eliminate it telling me that maybe lyme is messing somehow with Gaba production.

    When I take antibiotics (been on them for years) my nerves get worse and really bad a few days after. My theory is could it be that the antibiotics are killing off the good gut flora which produce GABA and lowering my levels causing more severe nerve pain?

    Second what would you suggest is the top few things to take to improve GABA levels?
