What Is Glutathione?
Glutathione (GSH, CAS 70-18-8; INCI: Glutathione) is a tripeptide — composed of L-glutamate, L-cysteine, and glycine — naturally synthesized in every human cell. Often called the “master antioxidant,” it is a white to off-white fine crystalline powder, highly soluble in water, and stable when properly stored. As a fundamental raw material for nutricosmetics, dietary supplements, and functional skincare, glutathione is valued for its purity and bioavailability in finished formulations.
How It Works
Glutathione neutralizes free radicals directly and, more importantly, recycles other antioxidants such as vitamins C and E, restoring their activity. Its thiol group donates electrons to quench reactive oxygen species, protecting cellular membranes, mitochondria, and DNA from oxidative stress. Beyond antioxidant action, glutathione is the body’s primary phase-II detoxification cofactor, conjugating toxins in the liver for safe elimination. This dual role underpins its reputation for supporting skin clarity, immune resilience, and healthy aging at the cellular level.
5 Key Application Areas
- Skin brightening & even tone: inhibits tyrosinase activity to reduce the appearance of dark spots and support a luminous complexion.
- Oral beauty supplements: formulated into capsules and effervescent tablets for antioxidant and radiance support.
- Detox & liver support: a core ingredient in cleanses and hepatic-health formulations.
- Anti-aging nutricosmetics: protects cells from oxidative damage linked to premature aging.
- Immune & sports recovery: helps replenish intracellular glutathione depleted by intense training and stress.
