Vitacost, GABA Gamma - Aminobutyric Acid, 1000 mg per serving, 200 Capsules

Vitacost GABA Gamma-Aminobutyric Acid provides 1000 mg of GABA per serving in a 200-capsule bottle. GABA (gamma-aminobutyric acid) is a neurotransmitter that acts as an inhibitory signal in the nervous system. While GABA is not a standard protein-building amino acid, it is derived from glutamate through a decarboxylation process. This supplement offers GABA in convenient capsule form. Individual responses to neurotransmitter-related supplements can vary significantly based on numerous physiological factors.
