Gamma-Aminobutyric acid, or γ-aminobutyric acid /ˈɡæmə əˈmiːnoʊbjuːˈtɪrɪk ˈæsɪd/, or GABA /ˈɡæbə/, is the chief inhibitory neurotransmitter in the developmentally mature mammalian central nervous system. Its principal role is reducing neuronal excitability throughout the nervous system. GABA is sold as a dietary supplement in many countries. It has been traditionally thought that exogenous GABA (i.e. taken as a supplement) doesn't cross the blood-brain barrier, however data obtained from more current research indicates that it may be possible.
