Gamma-aminobutyric acid (GABA) is an amino acid that serves as the primary inhibitory neurotransmitter in the brain and a major inhibitory neurotransmitter in the spinal cord.
Researchers suspect that GABA may boost mood or have a calming, relaxing effect on the nervous system.
Low levels of GABA may be linked to:
-
Anxiety or mood disorders
-
Epilepsy
-
Chronic Pain
