GABA for Anxiety

As with most dietary supplements, GABA (gamma-aminobutyric acid) is claimed to work for a variety of different uses, including for treating anxiety. However, there is actually very little evidence to suggest that GABA supplementation works for any use.
 
GABA is the primary inhibitory neurotransmitter in the central nervous system. This means that when GABA binds to receptors, it usually decreases the chance that a nerve will "fire" and send out a signal. Although drugs that act like GABA 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 GABA will produce similar effects.
 
There is little, high-quality evidence to show that using GABA for anxiety treatment is effective. As is often the case with dietary supplements, some of the more outlandish claims about the health benefits of GABA should be viewed with skepticism (or, at the very least, with caution) until more research is available.
