Glutathione
THE MASTER ANTIOXIDANT
GSH; L-Glutathione; Reduced Glutathione
Glutathione is your body's main antioxidant, made from three amino acids in your liver. It protects every cell from damage, helps detoxify harmful substances, and supports immune function. Levels decline with age and stress, making supplementation valuable for anti-aging and detoxification.

Three amino acids and a distinctive bond
Glutathione is the tripeptide gamma-L-glutamyl-L-cysteinylglycine, made from glutamate, cysteine and glycine. The gamma designation describes the connection through glutamate's side-chain carboxyl group rather than the usual alpha-carboxyl linkage of a peptide backbone. That bond arrangement is part of its molecular identity.

Compound evidence
Oral glutathione lightened sun-exposed skin modestly in small trials
Oral glutathione modestly reduced melanin in small, short trials, mostly on sun-exposed skin. IV glutathione lacks supporting trial evidence.
Compound evidence
Oral glutathione raised blood levels in some trials but not others
Oral glutathione raised blood levels 30-35% in a 6-month trial but not in a 4-week one. IV glutathione's best trial protected against cisplatin neuropathy.
