Why GABA is good for you

Gamma-amino butyric acid (GABA) is a non-essential amino acid which is necessary to ensure that the brain (especially the neurons or nerves) function properly. GABA's main role is to decrease neuron activity and inhibit nerve cells from over-firing. Together with niacinamide and inositol, it prevents anxiety and stress-related messages from reaching the motor centers of the brain by occupying their receptor sites, thus blocking these sites from the impulses.

asically GABA helps the body to relax.
