Glutathione (GSH) is an endogenous tripeptide composed of glutamate, cysteine, and glycine. It is the primary intracellular antioxidant in mammalian cells, serving as the electron donor for glutathione peroxidase and participating in phase-II conjugation reactions that detoxify electrophiles and heavy metals.

Glutathione is used in oxidative-stress research, liver-detoxification model systems, and redox-balance studies. The GSH:GSSG ratio is a primary biomarker of cellular oxidative state.

Frequently Asked Questions

What form of glutathione is this?
Reduced glutathione (GSH), the bioactive form that serves as an electron donor in redox reactions.

What is its purity?
~99% HPLC purity, third-party verified.

How is glutathione stored?
Lyophilized: -20°C. After reconstitution, use quickly because reduced glutathione oxidizes in solution.
