Glutathione is the primary endogenous low-molecular-weight thiol tripeptide, functioning as the master intracellular antioxidant, nucleophilic detoxicant, and redox regulator

Supply duration: 8 to 12 weeks continuous, followed by a 4-week washout phase. Frequently stacked with ascorbic acid to keep the tripeptide in its active reduced state.

Operates as an essential electron donor for glutathione peroxidase (GPx), neutralizing hydrogen peroxide and lipid hydroperoxides9. Serves as a substrate for glutathione S-transferases (GSTs) during Phase II hepatic detoxification, conjugating lipophilic electrophiles into water-soluble mercapturic acid derivatives for biliary and urinary excretion
