Glutathione (GSH) is the most abundant intracellular antioxidant in the body — a tripeptide of glutamate, cysteine, and glycine that serves as the primary substrate for glutathione peroxidase (GPx) enzymes, glutathione S-transferases in Phase II liver detoxification, and the thioredoxin/glutaredoxin redox buffer systems. Intracellular GSH declines with age, chronic illness, and toxin exposure. The reduced (L-GSH) form maintains the active sulfhydryl (-SH) group essential for antioxidant and detoxification function. In human trials, 500 mg/day oral GSH over 3 months increased red blood cell glutathione by 35% and significantly reduced plasma oxidative stress markers. GSH also inhibits tyrosinase — the rate-limiting enzyme in melanin biosynthesis — contributing to its skin-brightening effect documented in multiple clinical trials.
