GABA (Gamma-Aminobutyric Acid) is one of the more potent neuroactive peptides that is contained within brain tissue. This is because it is the primary inhibitory neurotransmitter in the mammalian central nervous system. Even though GABA taken orally is not very bioavailable, some amount may reach the brain and exert certain effects. GABA can help support calm, relaxation, and support healthy sleep habits.
