Does glutathione supplementation actually work?

The evidence is mixed. Glutathione is the body's own master intracellular antioxidant, and it is sold as a supplement, including injectable forms the FDA has flagged as not approved drugs, for detoxification and skin brightening. This site's review found 3 citations, 2 of them human, and the clinical evidence for supplementation raising the body's own glutathione levels meaningfully is not consistently strong across that record.
