Glutathione: The Body’s Master Antioxidant in Cellular Research
Why glutathione is central to oxidative-stress and detoxification research.
Often called the body’s “master antioxidant,” glutathione appears in virtually every cell and is one of the most frequently referenced compounds in oxidative-stress and detoxification research.
What glutathione is
Glutathione is a tripeptide (glutamate, cysteine, glycine) that cells use to neutralize reactive oxygen species and support detoxification enzymes. Its reduced-to-oxidized ratio is a research marker of a cell’s oxidative state.
Why it’s studied
Research examines glutathione in cellular defense, mitochondrial function, and the regeneration of other antioxidants such as vitamins C and E. Because levels vary with age and stress, it is a common variable in aging and metabolic studies.
The quality factor
Glutathione is sensitive to oxidation, so identity and purity documentation are especially important for reproducible research — a per-batch COA and third-party HPLC testing.
Research-grade Glutathione from Prestige Sciences — ≥99% purity by HPLC, a Certificate of Analysis on every batch, U.S.-shipped with insured delivery.
