GABA (Gamma aminobutyric acid) functions as a neurotransmitter in the central nervous system. It is as an amino acid and is present in animals as well as various plant forms. It was discovered over 20 years ago that it could be supplemented in food and food products. It has been used extensively over the past five years – especially in Japan and some other Asian countries, in food and beverages, being promoted as way to combat stress and anxiety, and to calm and relax individuals. Some examples of GABA supplemented food and beverage products are iced coffee and tea drinks, sports drinks, energy drinks, juices and meal replacement liquids etc. The Aquarius Sharp Charge drink is a notable example that was produced by Coca Cola in Japan and contains GABA to help “improve and relax the mind.”
Although GABA is produced and functions primarily in the brain, it has not yet been proven that a GABA supplement, taken orally, can be effectively transported through the bloodstream to the brain. Or if it can make it to the brain, there is not yet enough scientific evidence of how much and how effective it is in reality. It has been theorized that GABA cannot pass the blood-brain barrier and because of this, direct GABA supplementation through food and beverages may not make it through to the brain. Although, given the evidence of the positive effects and measured results from many of those taking GABA supplements there must be some getting through.
As far a GABA being effective in increasing HGH levels, this is not so much relative to GABA reaching the brain, as increased HGH levels are caused by the triggering of growth hormone releases and is more affected by the blood concentrations of GABA. In this way, an increase in GABA levels in the bloodstream via a GABA supplement could positively affect HGH secretion. GABA’s ability to calm a person’s nerves and reduce stress and anxiety – similar to a benzodiazepine such as valium can also encourage release of growth hormones.
Most GABA supplements are relatively low cost and there seems to be no evidence of negative side effects, so if you are struggling with some of the ailments that GABA is known to impact, such as depression, high blood pressure, obesity, stress and anxiety, excessive aging, etc and generally feeling down and out, then give it a try. Of course the best GABA supplement is GABA is in its natural form of GABA tea. Drinking this inexpensive Chinese tea regularly can have an amazingly positive effect in a short amount of time.
