How Glutathione works, and what the research shows.
Glutathione is the body's principal intracellular antioxidant — a tripeptide (glutamate-cysteine-glycine) that neutralizes reactive oxygen species, regenerates vitamins C and E, and serves as the substrate for the liver's phase II detoxification enzymes.
Levels decline with age and oxidative stress; injection bypasses the poor oral bioavailability of glutathione taken by mouth.
Glutathione's biochemistry is textbook-established, and deficiency states are well documented.
Clinical trials of supplemental glutathione are smaller: studies show oral absorption is poor, while injectable and IV administration reliably raises levels; small human trials in skin and neurological conditions have produced mixed results.
Injectable glutathione is prescribed as supportive therapy at physician discretion.
