Gamma-aminobutyric acid is one of the most important amino acids for the regulation of the body’s nervous system. GABA acts as an inhibitor of nerve impulses, which in other words means: “inhibits”. GABA is a natural substance for the body. With its insufficiency, inhibition is not sufficiently pronounced, which causes a number of disorders of the nervous system.
