About Glutathione

Glutathione is the tripeptide gamma-glutamyl-cysteinyl-glycine, made in every cell and present at millimolar concentrations as the main intracellular antioxidant and a cofactor for detoxification; the gamma-linkage between glutamate and cysteine makes it resistant to ordinary peptidases and a substrate for gamma-glutamyl transpeptidase, so injected glutathione is cleared from plasma in about 14 minutes and acts largely as a cysteine source. Reduced glutathione has been infused intravenously in small trials for Parkinson's disease, as a neuroprotectant alongside cisplatin and, in one placebo-controlled study, for skin lightening, where liver test abnormalities and an anaphylactic reaction were recorded. No injectable glutathione is FDA-approved; it is dispensed as a compounded 200 mg/mL preparation and sold as a research chemical, and the FDA warned in 2019 and again in 2026 about serious reactions traced to dietary-supplement-grade powder with excess endotoxin being compounded for injection. The 200-600 mg intramuscular or subcutaneous doses in community use have never been tested in a controlled trial, whereas oral glutathione at 250-1,000 mg a day raised body stores in a 6-month randomized study.
