What is L-Glutathione (Reduced Form)?

L-Glutathione (L-GSH) is a tripeptide composed of glutamate, cysteine, and glycine. The “reduced form” refers to its active thiol (–SH) state, which allows it to function effectively as an antioxidant. Unlike its oxidized counterpart, reduced glutathione powder is biologically active and immediately available for formulations in dietary supplements, functional foods, and topical cosmetic products.
