Gamma-aminobutyric acid (GABA) is a neurotransmitter, or chemical messenger, in the brain. It is a natural calming and anti-epileptic agent made in the brain that is manufactured from glutamine and glucose. The brain contains many neurotransmitters that trigger or inhibit specific reactions in the body. GABA calms the nervous system by preventing the transmission of certain signals. ‡

GABA is the primary inhibitory neurotransmitter in the central nervous system and participates in cell-to-cell communication. Healthy GABA levels have been associated with positive mood. A recent study indicates that GABA also enhances alpha wave production in the brain to promote relaxation and moderate occasional stress. In the same study, it supported healthy IgA levels, suggesting that it may support immune health during occasional stress.‡

Too much excitation can lead to irritability, restlessness, sleeplessness, and spasmodic movements which requires balancing. GABA, as an inhibitory neurotransmitter, can provide this balance. Studies also indicate GABA can promote relaxation and enhance sleep. Research indicates that low GABA levels or decreased GABA function in the brain may have an adverse impact on neurological health.‡
