L-Glutathione

L-Glutathione (γ-glutamyl-cysteinyl-glycine) is a tripeptide present in virtually every cell of the human body and serves as the master intracellular antioxidant. It plays critical roles in neutralizing reactive oxygen species (ROS), regenerating other antioxidants (Vitamins C and E), detoxifying xenobiotics and heavy metals via conjugation reactions, and supporting immune cell function. Glutathione levels decline significantly with age, chronic disease, and environmental stress exposure. Clinical research supports supplementation for conditions including liver disease, neurodegenerative disorders, and immune dysfunction. We supply pharmaceutical-grade reduced L-Glutathione in bulk quantities for supplement manufacturers, pharmaceutical companies, and IV therapy clinics.
