Swanson Maximum-Strength GABA Gamma Aminobutyric Acid is a dietary approach to ease stress and tension and promote relaxation. GABA is a compound produced in the brain from glutamine and glucose. It functions as a calming neurotransmitter within the central nervous system, thereby influencing our reactions to stress and our levels of excitability and tension. Many people also find GABA helpful in promoting a sound and satisfying night of sleep, as well as a boost to general fitness. If you're looking for a GABA max dosage supplement to calm daily tension, our Maximum Strength GABA provides the widely recommended amount of 750 mg in each vegetarian capsule.
