Immune Modulator

Glutathione

Also known as: GSH

Glutathione is an endogenous tripeptide (gamma-L-glutamyl-L-cysteinyl-glycine) that serves as the principal intracellular antioxidant in mammalian cells. It is not FDA-approved as a drug in the US; parenteral glutathione is used off-label (and in some compounding settings) for oxidative stress, hepatic support, and — controversially — skin lightening. The FDA has warned against injectable glutathione for skin lightening (2019) due to reports of serious adverse events.
