Description Gamma-aminobutyric acid (GABA) is commonly taken to induce relaxation and as a sleep aid. GABA serves to fill brain receptor sites so that other messages cannot be transmitted, allowing for calmness and relaxation. While GABA is an amino acid, it is classified as a neurotransmitter. It is the most abundant inhibitory neurotransmitter in the brain and can influence brain function. Kirkman’s GABA is made from the highest quality, purest GABA available.
