Kirkman offers 250 mg GABA capsules in a hypoallergenic formulation designed for individuals with special requirements and sensitivities.

Gamma-aminobutyric acid (GABA) is the most abundant inhibitory neurotransmitter in the brain. It serves to fill brain receptor sites so that other messages cannot be transmitted.

While GABA is an amino acid, it is classified as a neurotransmitter (a substance deposited at the end of nerve cells that is then picked up by other nerve cells in order to send nerve impulses throughout the brain and nervous system).

GABA is known to induce relaxation and improve restful sleep.

Suggested Use

1-3 capsules daily or as directed by a physician.

Other Ingredients

Gamma-aminobutyric acid, plant cellulose, silicon dioxide, plant cellulose capsule.

Free Of: Sugar, starch, soy, wheat, casein, gluten, milk, corn, egg, preservatives, yeast, gelatin, flavorings, colorings, peanuts, tree nuts or fish.

This GABA works affordably

Posted by CharlotteJernigan on Sep 16, 2017 | Verified Purchase

This product effectively helps me fall asleep and sleep well with a bonus: The return of early morning dreaming which I enjoy and have missed in times of poor sleep. I am a 150 pound adult and I tolerate higher doses of many supplements. Through experimentation, I have determined that 4 capsules about 30-minutes before sleep is optimal in times of high activity and stress during the day. This is a 1 gram dose. (Doses of up to 3 grams daily are generally considered safe but you should confirm your own dose with your health care professional.) One minor drawback is that I am more drowsy when I first wake up but the trade off of good sleep is worth it for me. On less stress-filled days, I may take only 2 capsules per night. I have compared the 1 gram dose of this brand of GABA to both a 1 gram and a 1.5 gram dose of the N_w 500mg caps. That brand just does not have the same effect at either dose level. Neither KL nor N_w specify if their GABA is naturally derived from the fermentation process that utilizes Lactobacillus hilgardii. I plan to ask this in the new "Questions" feature. All I can say is that this one works for me and the other does not, even using a similar or higher dose. I have not yet tried the Th_rne brand of GABA 250 which does use Lactobacillus hilgardii fermentation to produce the "natural GABA" that has the research to support its benefits. Unfortunately, unless the Th_rne brand allows me to consistently cut my dose by half or more, it is not affordable for my nightly use. If/when I ever try that one, I will update this review. ++cj

I had purchased a very expensive product from my naturopath for anxiety. I've found that this works just as well. I recommend it.
