Glutathione (CAS 70‑18‑8) is a tripeptide antioxidant with well‑defined chemical properties, biological functions, and multiple commercial configurations ranging from reduced powder to advanced liposomal and acetylated forms. It is widely used in pharmaceuticals, cosmetics, and nutraceuticals for detoxification, immune support, and skin health

KEY FEATURES 

Master Antioxidant: Neutralizes free radicals, peroxides, and heavy metals.

Cellular Protection: Maintains redox balance by reducing disulfide bonds in proteins.

Detoxification Role: Conjugates with drugs and toxins to enhance solubility for excretion.

Immune Support: Cofactor for enzymes involved in immune defense.

Skin & Cosmetic Use: Applied for skin brightening and anti‑aging formulations.

Clinical Marker: Ratio of reduced (GSH) to oxidized (GSSG) glutathione is used to measure oxidative stress.
