Glutathione
Glutathione — The Master Antioxidant
- Supports antioxidant defence
- Supports detoxification
- Supports skin brightness
Overview
Glutathione is a tripeptide of glutamate, cysteine and glycine, and the body's principal intracellular antioxidant — which is why it is commonly called the master antioxidant. It is supplied as a lyophilised powder in a sealed vial for laboratory and in-vitro research.
PepSource supplies Glutathione in a 1500mg vial. Every batch is independently third-party tested for HPLC purity and mass-spectrometry identity, and the certificate of analysis for the batch you receive is published on our lab results page.

Research Focus
Glutathione sits at the centre of cellular redox biology. Published research has examined its scavenging of free radicals and role in oxidative stress; phase II detoxification, where it conjugates to toxins to make them water-soluble for excretion; maintenance of cellular redox balance; and skin pigmentation, where studies have examined its effect on melanin synthesis.
Research on glutathione includes both human studies and animal models.
Testing & Certificates of Analysis
Each batch is tested by an independent analytical laboratory for HPLC purity and mass-spectrometry identity before release. Certificates are published per batch and searchable by lot code on our lab results page — you can verify the exact vial you were sent.
