Gamma-aminobutyric acid (GABA) is an amino acid derivative and an inhibitory neurotransmitter. Neurotransmitters are chemical messengers that carry messages between nerve cells or from nerve cells to other target cells. GABA is synthesized from the amino acid glutamic acid. It has an inhibitory effect on the firing of neurons and supports a calm mood.
