“Tens of millions of symptom-specific prescriptions are written, but only a few address the GABA deficiency causing them.” – Dr. Eric Braverman
I believe that Dr. Braverman is correct in that GABA deficiencies are often overlooked in psychiatry and that millions of people may be missing out on more GABA targeted therapies.
What is GABA?
GABA (Gamma-aminobutyic acid) is an inhibitory neurotransmitter that has a calming effect on the brain and body. Why is it that medicine often fails at addressing this problem?
I can remember, in my early twenties, when I sought out counseling for anxiety and was put on a serotonin based antidepressant (SSRI). Neither counseling nor the SSRI treatments helped. I can remember asking my psychologist if there were any drugs out there that more specifically treat anxiety. It turns out that drugs that directly increase GABA are more effective in treating anxiety symptoms, but most doctors are hesitant to prescribe GABA based drugs due to their known side effects. As a result, SSRIs are often perscribed as the side effects are generally less severe than the GABA based drugs.
GABA stands for gamma-aminobutyric acid which is an amino acid working as a neurotransmitter. It provides balance in the brain and helps in the induction of sleep and relaxation.
Apart from this, the GABA performs several other functions. Since a long time, lots of research has been conducted on the benefits and effects of GABA. It has been found that GABA has the capability to help increase the levels of the plasma growth hormone.
It promotes the production of Human Growth Hormone which in turn helps in the building of muscles and prevention of fat build-up in the body.
Here are few of the benefits of HGH, the production of which is increased by GABA:
With the progression of age, the levels of HGH decrease. Therefore, the production has to be facilitated with the help of effective supplements.
The lean muscles of the body become stronger with the help of the human growth hormone while several positive anti aging effects are observed.
In a study conducted by the First Medical Clinic at the University of Milan, Milan, it was found that within just 90 minutes of using the GABA supplements in the human body, the levels of HGH increases up to about 5 times.
19 subjects were taken in this research and they were made to consume about 5 grams of GABA orally. They were compared to 18 other placebo subjects. After a period of about 90 minutes the results found showed that the amount of HGH in the GABA group increased about 5 times.
Research also shows that consumption of only 2 grams of GABA proves to be effective. However, when 5 grams are taken it serves to be much more effective and maximum effects are attained when the intake is 18 grams.
Continuous studies are being undertaken to find out whether it should be taken intravenously or orally. It has been thus found that taking it intravenously shows much better results in comparison to the oral consumption. Irrespective of this majority of the supplements of GABA are made to consume orally.
There are however, few side effects of GABA. Studies have reported that some users have felt gentle itchy feeling around their face and neck after GABA intake.
Some users have even noticed a slight change in their heart beat or breathing patterns. However, there is nothing to be worried because these side effects are temporary and are not harmful.
At the same time, they are very rare and you might not experience these effects at all. Since GABA has a sedative effect, one can take it before sleeping.
How do you increase GABA levels safely and effectively without medical drugs? There are several things you can do
The doctors I have talked to over the years often prescribe SSRIs to help put the brakes on the brain for those who are overly amped up. Essentially, serotonin and GABA are the brakes and Acetylcholine and Dopamine are the gas. When it comes to anxiety issues, I think SSRIs are analogous to using the emergency brake on your car to slow down the vehicle as opposed to applying the real brakes.
There are bodies of research showing that SSRIs have positive effects on GABA levels that are noteworthy (1,2). I would guess that some psychiatrists may prescribe SSRIs for those who are non-responsive to GABA drug based treatments. I’ve also read that SSRIs can be helpful for those withdrawing from GABA based drugs. I’m not a psychiatrist nor do I pretend to be. I’ve just seen so many people with anxiety based issues taking SSRIs that are not getting better.
If you have anxiety and are not responding do SSRIs, you may want to consider increasing your GABA levels. Of course, you’ll want to consult your doctor before making any changes.
1. Eat foods containing higher levels of glutamic acid
The world’s leading brain expert Dr.Eric Braverman has identified a list of foods higher in glutamic acid which can help form GABA in the brain (3).
Glutamic Acid/Glutamate (Forms Glutamine) MGS. Per 6-8 OZ. Serving
Almonds, tree nuts (10.3 g.)
Banana (220 mg.)
Beef liver (6.5 g.)
Broccoli (740 mg.)
Brown Rice (940 mg.)
Halibut (7.9 g.)
Lentils (2.8 g.)
Oats, whole grain (7.4 g)
Oranges, citrus fruits (210 mg.)
Potato (830 mg.)
Rice Bran (3.7 g)
Spinach (680 mg.)
Walnuts, tree nuts (5.4 g.)
Whole Wheat, whole grain (8.6 g.)
2. Exercise a minimum of 4 times per week
Exercise helps restore levels of all neurotransmitters. On a relevant side note, the euphoric feeling some people get when exercising (more so with aerobic conditioning) has been attributed to endorphins, but there is no research to prove endorphins are responsible for this. More than likely, the rush of serotonin is responsible for the uplifting mood during exercise (3).
There has been a couple of small studies indicating that yoga helps increase GABA (4), but I would bet you could get a similar effect anytime you increase exercise levels of any kind.
3. Boost your Vitamin B-6 intake (or take a B-Complex)
Vitamin B6, if deficient, may impair the production of GABA as it is a cofactor nutrient. For a better understanding of cofactor nutrients read this article. Since overt vitamin deficiencies are rare, we use urine organic acids testing (UOA) to determine if there are any functional deficiencies. So far in the UOA testing at our clinic, we have yet to find anyone who is not deficient in the B-complex vitamins.
4. Get a comprehensive urine organic acids test
I cannot speak highly enough on how much this test has helped our patients and clients. If you can determine functional deficiencies via (UOA) and reverse them, you will likely help all of your neurotransmitters and help optimize brain function.
5. Use calming nutrients to help improve sleep quality
Getting quality sleep can help ensure all neurotransmitters and hormones are balanced and sufficient (6). My top 2 supplements for increasing sleep quality are:
Magnesium-l- Threonate (As Neuromag): This is the only form of magnesium that has the ability to raise magnesium levels within the brain. To read more on the details of magnesium threonate, read this.
Insomnitol is great for those who need more of a target approach to sleep. It contains valerian root, lemon balm, passion flower, chamomile, l-theanine, 5HTP and melatonin.
6. Possible GABA benefit from short term Magnolia Bark use (Magnolia officinalis)
Magnolia bark is an herb that has been used in Chinese medicine for centuries and has been shown to increase GABA levels in mice (7). Relora (a proprietary blend of patented extracts from magnolia and phellodendron) has been shown in some small studies to help with relaxation and emotional well-being (8). I remain hopeful that the relaxation response results from these studies could be a reflection of increases in GABA, but for right now claims cannot be made. Magnolia bark may be worth a try as a part of an overall anxiety reduction program, but probably should not be used as a first line of defense.
7. Possible GABA benefit from inositol
Inositol has been used in psychiatry to help treat of anxiety and depression. Inositol is part of a messenger system that can help improve GABA and serotonin levels (9).
Fear and anxiety is good for us; it protects us from danger, keeps us sharp and makes us learn how to avoid unpleasant situations. However, when anxiety levels start to impair our function, it is important to know how to reduce them. If you think you may be having minor situational anxiety troubles, I suggest trying the strategies 1,2,3,4,6 and 8 listed above. For strategies 5 and 7 (UOA testing and for herbal formulas) you should contact your doctor.
