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.

Glutathione Supplementation in Parenteral Nutrition to Prevent Oxidative Stress Related Complications in Preterm Infants: Preclinical Efficacy and Safety Profile
Numerous adverse effects caused by oxidative stress are commonly observed in preterm infants. This stress is caused by the oxidative burden resulting mainly from supplemental oxygen and parenteral nutrition (PN), and by their precarious antioxidant defense system.

Glutathione in Our Diet and Its Role in the Body: From Disease Prevention to Anti-Aging
Background/Objectives : Glutathione (GSH) is a fundamental tripeptide essential for maintaining cellular redox homeostasis, detoxification, and immune regulation. While GSH is synthesized endogenously, its levels typically decline with age, potentially increasing susceptibility to oxidative stress-related conditions.
