GABA

GABA (Gamma-Aminobutyric Acid) is a naturally occurring non-protein amino acid that acts as the primary inhibitory neurotransmitter in the human central nervous system. It functions as a neurological 'brake,' dampening overstimulation and promoting physical and mental relaxation. As a dietary supplement, it is typically produced through the fermentation of specific bacteria (such as Lactobacillus hilgardii, commonly marketed as PharmaGABA) and is utilized to manage stress, improve sleep quality, and support neurological balance.
