͢Chewable GABA Orange from NOW Foods is a non-protein amino acid that functions as a neurotransmitter in the human brain. GABA is known as the brain’s own calming agent and is naturally produced in the body. By inhibiting over-stimulation of the brain, GABA may help promote relaxation and ease nervous tension. NOW provides only the naturally occurring form as found in food and in the body. Chewable GABA combines this naturally occurring neurotransmitter with the amino acids Taurine and Theanine for their synergistic effects.
