GABA is the primary inhibitory neurotransmitter in the central nervous system, playing a central role in regulating cell-to-cell communication. Healthy levels of GABA have been associated with positive mood. GABA enhances alpha wave production in the brain to promote relaxation and moderate occasional stress. Studies suggest that GABA could work effectively as a natural relaxant and its effects could be seen within one hour of administration to induce relaxation and diminish anxiety. GABA supports healthy IgA levels in humans, suggesting that it may support immune health during occasional stress conditions.
