Glutathione (GSH) is a three-amino-acid peptide that serves as the body’s principal antioxidant and a central hub of redox balance, detoxification, and cellular thiol defence.
One-paragraph overview from our research datasheet — still scientific, but faster to read than the full mechanism list below.
Glutathione (GSH) is the body’s principal endogenous antioxidant — a γ-glutamyl-cysteinyl-glycine tripeptide central to redox balance, Phase-II detoxification, and cellular thiol defence.
Peer-reviewed literature typically discusses Glutathione in specific experimental settings. The points below reflect how the scientific community frames this compound—not as health claims, but as the research questions being asked.
Research vs. personal use: Literature describes experiments in controlled lab and animal models. This is distinct from any real-world use; our products are for laboratory research only.
Researchers study these compounds for mitochondrial function, nutrient sensing, and cellular energy stress responses -often in ageing or metabolic disease models.
Our datasheet lists mechanistic themes observed in preclinical work. These are research endpoints, not health claims. They help scientists understand and compare pathways.
Storage requirements: Lyophilised powder: store in freezer (−20 °C), protected from light and moisture. Reconstituted: refrigerate 1–6 °C and use promptly — reduced glutathione oxidises to GSSG on exposure to air. Use within the validated stability window for the specific batch. · Learn best practices in our detailed storage guide.
Research dosing context: Literature typically discusses 600–1500 mg per preparation (research-protocol range) · Intermittent dosing in published research protocols; intravenous and intramuscular routes are most common · Intravenous glutathione has a short plasma half-life (on the order of minutes) due to rapid turnover by γ-glutamyl transferase at the cell surface; oral GSH bioavailability is poor because it is hydrolysed in the gut, which is why injectable and precursor strategies (e.g. NAC) dominate the literature. These figures describe the research context and are not a dosing recommendation. Material is for laboratory research only.
Preparation steps: Follow our detailed reconstitution guide, use the calculator tool for volume confirmation, and always verify purity with the COA reading guide.
Glutathione (GSH) is studied as the body’s principal antioxidant and a hub of redox balance and detoxification. Research examines its role in scavenging reactive oxygen species, powering glutathione peroxidase enzymes, buffering the cellular redox state via the GSH/GSSG ratio, supporting Phase-II detoxification, and — separately — its effect on skin pigmentation via tyrosinase. It is supplied here for laboratory research only and is not for human use.
Because it is both the most abundant small-molecule antioxidant in the cell and a central node that supports the others — it powers the glutathione peroxidase enzymes that break down peroxides and regenerates the oxidised forms of vitamins C and E, effectively recycling the wider antioxidant network rather than acting alone.
GSH is reduced (active) glutathione; GSSG is the oxidised form, made of two glutathione molecules joined by a disulfide bond. GSH donates electrons and becomes GSSG; the enzyme glutathione reductase regenerates GSH from GSSG using NADPH. The ratio of the two (normally heavily weighted toward GSH) is a standard laboratory measure of oxidative stress.
Oral glutathione is poorly bioavailable because it is largely hydrolysed in the gut before absorption. That is why research protocols favour intravenous or intramuscular routes, or precursor strategies such as N-acetylcysteine (NAC) that help cells make their own glutathione. Note that injected GSH also clears from plasma quickly, within minutes, due to rapid enzymatic turnover.
Keep the lyophilised powder frozen at −20 °C, protected from light and moisture. After reconstitution, refrigerate at 1–6 °C and use it promptly — reduced glutathione oxidises to GSSG on exposure to air, so minimise headspace and avoid prolonged storage of the dissolved solution.
