Glutathione (γ-L-glutamyl-L-cysteinylglycine) is the body’s most abundant endogenous antioxidant—a tripeptide synthesized in virtually every cell from glutamine, cysteine, and glycine. It is the central hub of cellular redox regulation and detoxification.
Glutathione neutralizes reactive oxygen species directly, recycles and regenerates other critical antioxidants including Vitamins C and E, and drives Phase II hepatic detoxification by conjugating heavy metals, xenobiotics, and carcinogens for excretion. It also maintains T-cell proliferation and NK cell activity, making it essential to immune function.
Research consistently shows that systemic glutathione depletion correlates with accelerated biological aging, neurodegeneration (Parkinson’s, Alzheimer’s), metabolic syndrome, and immunosuppression. Exogenous administration via injection or nebulization bypasses gut-mediated degradation and achieves the intracellular concentrations oral supplementation cannot.
