Commonly written as GSH, reduced glutathione, glutathione peptide or L-glutathione, it is the tripeptide antioxidant central to cellular redox balance.

It is the most abundant low-molecular-weight thiol in animal cells, present at millimolar concentrations, and it exists in a reduced form (GSH) with a free sulfhydryl group and an oxidised disulfide form (GSSG). It was named by Frederick Gowland Hopkins in 1921 and its structure was settled in 1935. It is often written as L-glutathione, reduced glutathione, GSH or glutathion, and searches for glutathione 600mg refer to the reduced form supplied here.\u003c\/p\u003e\n\u003cp\u003eGlutathione is studied in three main directions: oxidative stress and redox signalling, where the GSH to GSSG ratio is the principal measure of a cell's redox state; detoxification, where it conjugates reactive electrophiles and drug metabolites for excretion; and models of neurodegeneration, liver injury and ageing in which glutathione depletion is a consistent finding. It works by donating electrons through its cysteine thiol, either directly to reactive oxygen species or as the substrate for glutathione peroxidase and glutathione S-transferase enzymes, and it is then recycled from GSSG by glutathione reductase using NADPH.\u003c\/p\u003e\n\u003cp\u003eOmega Peptides Australia supplies Glutathione as a high-purity (≥99% HPLC) COA-verified lyophilised powder in a sealed sterile 600mg vial.

Research measures the GSH to GSSG ratio, normally well above 100 to 1 in healthy cells, as a readout of oxidative stress in models of inflammation, ischaemia, radiation exposure and toxic injury.

The reduced form acts as an electron donor. Its cysteine thiol reacts with reactive oxygen and nitrogen species and with electrophiles, and glutathione peroxidases use it to reduce hydrogen peroxide and lipid hydroperoxides to water and alcohols. Two molecules of oxidised glutathione are joined by a disulfide bond as GSSG, and glutathione reductase regenerates GSH using NADPH from the pentose phosphate pathway, so the system is effectively a rechargeable redox buffer. Glutathione also reversibly modifies protein cysteine residues (S-glutathionylation), acting as a signalling switch, and stores nitric oxide as S-nitrosoglutathione.\u003c\/p\u003e\n\u003cp\u003eOutside the cell glutathione is broken down at the membrane by gamma-glutamyl transpeptidase, which is why orally ingested glutathione has limited bioavailability in pharmacokinetic studies and why much research uses precursors such as N-acetylcysteine or delivery formats that bypass the gut. In laboratory work the reduced form supplied here is the active species; the oxidised GSSG form, glutathione ethyl ester and liposomal preparations are different research tools with different properties. Unlike the receptor-targeting peptides elsewhere in this range, glutathione has no hormone-like signalling activity.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompound\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGlutathione, reduced (L-glutathione)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAlso known as\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGSH, reduced glutathione, L-glutathione, glutathion, gamma-L-glutamyl-L-cysteinylglycine, glutathione 600mg, glutathione peptide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCAS number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e70-18-8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMolecular formula\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eC10H17N3O6S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMolecular weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e307.32 g\/mol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSequence\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eγ-Glu-Cys-Gly (gamma-glutamyl linkage)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAntioxidant and redox research\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePurity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e≥99% HPLC · content 650.23 mg · Janoshik Analytical batch #199769 (9 July 2026) · \u003ca href=\"https:\/\/verify.janoshik.com\/tests\/199769-Glutathione_600mg_Sample_N5P9X5TE4N6F\" target=\"_blank\" rel=\"noopener\"\u003everify report\u003c\/a\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eForm\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLyophilised powder in a sealed sterile vial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVial sizes available\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e600mg — $149.99\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStorage (lyophilised)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2–8°C short term or −20°C long term, protect from light and moisture, avoid repeated freeze-thaw\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStorage (reconstituted)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2–8°C, use within 28 days\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eReconstitution\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBacteriostatic water (recommended)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003ch2\u003eAvailable sizes and pricing\u003c\/h2\u003e\n\u003cp\u003eGlutathione is supplied in a single 600mg vial, a much larger quantity than the milligram-scale peptides in the range because redox research uses it at far higher concentrations.
