GABA (Gamma-Aminobutyric Acid) is a naturally occurring non-proteinogenic amino acid that functions as a neurotransmitter in the central nervous system. It plays a critical role in reducing neuronal excitability, promoting relaxation, and supporting mental wellness. GABA is widely used in dietary supplements, nutraceuticals, and functional foods for cognitive support, stress management, and sleep enhancement. Its high-purity form ensures safety and efficacy in pharmaceutical and clinical applications.
