Purchase option
Glutathione (GSH) is a tripeptide (γ-glutamyl-cysteinyl-glycine) and the most abundant intracellular antioxidant in mammalian cells. It serves as the primary substrate for glutathione peroxidase and glutathione-S-transferase enzymes, which neutralize reactive oxygen species and facilitate Phase II detoxification. GSH levels decline with age, chronic illness, and oxidative load. Research into direct GSH supplementation spans immune function, mitochondrial protection, heavy metal chelation, and skin brightening pathways. Each vial contains 600mg reduced glutathione at ≥99% purity.
What it does

Product FAQ
Reduced glutathione (GSH) is the active, antioxidant form. Oxidized glutathione (GSSG) is the byproduct after neutralizing free radicals. The ratio of GSH:GSSG is a key marker of cellular redox status in research models.
Glutathione is sensitive to heat, light, and oxygen. Lyophilization preserves the reduced form; cold-chain shipping ensures the product arrives in its active state.
≥99% purity by HPLC, confirmed by identity testing. Full Certificate of Analysis provided with every order.
