L-Leucine USP is an essential branched-chain amino acid (BCAA) that plays a critical role in muscle protein synthesis, energy production, and tissue repair. Since it cannot be synthesized by the human body, it must be obtained through diet or supplementation. It is widely used in pharmaceuticals, nutraceuticals, sports nutrition, and fortified foods. Its USP grade ensures high purity and suitability for medical and nutritional applications.
