What is L-Glutathione?

L-Glutathione (γ-L-Glutamyl-L-cysteinylglycine) is the body's most abundant endogenous antioxidant tripeptide. It is present in virtually every cell and serves as the foundation of the cellular antioxidant defense system. As a domestic peptide Canada from Vancouver Island Peptides, our L-Glutathione is produced in British Columbia to research-grade standards — not imported.
