How Does Gamma-Aminobutyric Acid Work?Gamma-aminobutyric acid is the primary inhibitory neurotransmitter in the central nervous system in adults. This means that when gamma-aminobutyric acid binds to receptors, it usually decreases the chance that a nerve will "fire" and send out a signal. Although drugs that act like gamma-aminobutyric acid or increase the levels are useful for a wide variety of medical conditions, such as epilepsy and anxiety, there is no strong evidence that taking gamma-aminobutyric acid will produce similar effects.
Taking gamma-aminobutyric acid may either increase or decrease human growth hormone (HGH) levels and may increase the level of the hormones insulin and glucagon.
Is Gamma-Aminobutyric Acid Effective?There is little evidence to suggest that taking gamma-aminobutyric acid supplements is effective for any use (see Does GABA Work? for more information).
