The body's master antioxidant — a tripeptide essential for detoxification, immune function, and skin brightening.
A tripeptide (γ-Glu-Cys-Gly) produced in all cells, but most abundantly in the liver. Neutralises reactive oxygen species (ROS) via its thiol group, conjugates toxins for excretion (Phase II detoxification), recycles vitamins C and E, and inhibits tyrosinase enzyme — shifting melanin synthesis from eumelanin to phaeomelanin, producing skin-lightening effects.
Glutathione depletion is associated with virtually every major chronic disease and age-related condition. IV and SubQ administration bypasses the poor oral bioavailability of standard glutathione (liposomal forms have better oral bioavailability).
The skin-brightening effect is well-documented in clinical studies, resulting from competitive inhibition of tyrosinase (the rate-limiting enzyme in melanin synthesis). This application drives significant commercial and research interest in Asia.
