Gamma aminobutyric acid is an inhibitory neurotransmitter in the central nervous system. It regulates neuronal excitability throughout the nervous system. The Gamma Amino Butiric Acid is directly responsible for the regulation of muscle tone.
Gamma aminobutyric acid is the product of a biochemical decarboxylation reaction of glutamic acid by the vitamin pyridoxal, as well as from decarboxylase. Gamma aminobutyric acid blocks the transmission of a nervous signal from one cell to another in the central nervous system, preventing over-firing of the nerve cells.
Gamma aminobutyric acid is used to treat both epilepsy and hypertension where it is thought to induce tranquility in individuals who have a high activity of manic behavior and acute agitation.
