Glutathione 1500mg

What is Glutathione?

Glutathione is built from glutamate, cysteine and glycine and occurs naturally in most cells at relatively high concentration, making it the most abundant non-protein thiol in the body. Because it is endogenous rather than a novel synthetic sequence, research interest centers on modulating its levels and activity rather than characterizing a new compound.

This listing is Glutathione 1500mg from Purus Peptides (United States), sold on Stairway to Gray with escrow: your payment is held until the order arrives and only then released to the brand.

How it is understood to work

Its reactive cysteine thiol group allows glutathione to directly neutralize reactive oxygen species and to serve as the essential cofactor for glutathione peroxidase and glutathione S-transferase, enzymes central to cellular detoxification. It also helps regenerate oxidized vitamins C and E back to their active, reduced forms.

Research status

Glutathione is widely studied in oxidative stress, hepatic function, skin pigmentation, and immune and aging research, spanning cell-culture, animal, and some human clinical studies, particularly around liver protection and skin research. Bioavailability of exogenously supplied glutathione is an active area of methodological debate in this literature.
