Glutathione (GSH) is a tripeptide (glutamate-cysteine-glycine) that occurs naturally in cells as the primary endogenous thiol antioxidant. It's studied for its role in oxidative-stress and cellular-detoxification pathways.
Glutathione is studied for redox balance and is often grouped with skin/anti-aging and longevity discussions, though its mechanism (antioxidant/redox) is distinct from those compounds. It's frequently sold in large vials.
Glutathione ships in large vials (often 600–1500 mg), so compare on cost-per-mg. PepsTracker tracks it across 27 vendors. Platinum Peptides carries it, 15% off with pepstracker15.
Glutathione is an endogenous antioxidant tripeptide studied for oxidative-stress and cellular-detoxification pathways. It is sold for research use only.
Because it is the primary endogenous thiol antioxidant in cells, central to redox balance.
