GAD Support was created to assist patients who have difficulty producing adequate amounts of GABA, an important brain neurotransmitter. GABA plays the principal role of reducing excitability throughout the nervous system, as well as, regulation of muscle relaxation. Many individuals possess a genetic mutation of GAD (Glutamic Acid Decarboxylase), the primary enzyme that creates GABA. A weakness in the GAD enzyme creates an increased amount of Glutamate, the primary excitatory neurotransmitter of the nervous system, and a relative deficiency of GABA. This imbalance creates an overstimulated nervous system.
