Douglas Laboratories GABA 500 mg supplies 500 mg of gamma amino butyric acid per each capsule. 

GABA (gamma-aminobutyric acid) is an amino acid that functions as a neurotransmitter in the brain. GABA is synthesized in the brain from another amino acid, glutamate, and functions as an inhibitory neurotransmitter meaning that it blocks nerve impulses. 

In the body, GABA is concentrated in the hypothalamus region of the brain and is known to play a role in the overall functioning of the pituitary gland which regulates growth hormone synthesis, sleep cycles, and body temperature.
