Compound brief
Evidence brief. Not treatment advice or a safety clearance. Last evidence update: September 2026.
The cysteine thiol carries reducing power. Cells make it. Extracellular glutathione is not the same pool as mitochondrial NAD.
"Detox" and skin-lightening forum claims are not the chemistry of a thiol buffer.
Gamma-glutamylcysteine ligase and glutathione synthetase build it. Glutathione peroxidase uses it to reduce peroxides. Transferases use it to conjugate electrophiles.
The gamma linkage means it is not digested like a normal dietary peptide. What fraction of an injected dose becomes intracellular glutathione was not extracted.
Forum themes are unverified. They do not outrank a study, and they are not a dose.
Skin and detox anecdotes · unverified
Forums claim skin lightening and whole-body detox from glutathione. The thiol chemistry does not establish either outcome. Combination IV bags with NAD or vitamin C are common in those threads and are not seeded trials.
Theme summarized from public discussion. Not a quoted post, not a trial, and not a dose.
