PharmaGABA™ is naturally-sourced, bioidentical GABA (gamma-aminobutyric acid). It is made via a process where the amino acid glutamic acid (glutamate) is fermented using Lactobacillus hilgardii, the beneficial bacteria also used to ferment many foods including the vegetables in kimchi, the famous Korean dish. PharmaGABA™ provides 200 mg of GABA per serving (two tablets). Its chewable tablet delivery allows for rapid and efficient absorption and assimilation.* As a result, benefits are felt very quickly. GABA is a naturally occurring amino acid in the brain and is a major inhibitory neurotransmitter in the central nervous system (CNS). GABA serves as a critical calming agent for the body, helping to combat stress and anxiety. Made with non-GMO ingredients.
