Product overview
Glutathione is a naturally occurring compound inside cells. It plays a key role in protecting cells from damage. Researchers exploring oxidative stress often include glutathione in structured protocols. Oxidative stress occurs when unstable molecules damage cellular structures. This process is linked to aging and environmental exposure in research models.
L-glutathione is often referred to as the body’s master antioxidant. An antioxidant is a substance that helps neutralize free radicals. Free radicals are unstable molecules that can damage cells. Each vial contains 1500 milligrams of high-purity material. This concentration allows flexible laboratory measurement and controlled study design.
The material is suitable for cellular and biochemical research. It is not classified as medicines skin products, skin care formulas, or skin whitening cosmetics. It is not peptide cosmetics or support capsules. It is a laboratory-grade compound for structured research protocols.
Research focus
Glutathione plays a central role in cellular protection. Cellular protection refers to mechanisms that defend cells from damage. Research explores how glutathione interacts with oxidative stress markers. Oxidative stress may influence cellular aging and inflammation pathways in models.
In dermatological research settings, glutathione has been examined in relation to melanin production. Melanin is the pigment responsible for skin color. These investigations are part of controlled laboratory studies.
All potential applications relate strictly to in-vitro research. This product is not marketed as a skin lightening supplement or consumer support supplement. It is provided solely for laboratory investigation.
Methodological notes

What is L-Glutathione and why is it used in biochemical research?
L-Glutathione (γ-glutamyl-cysteinyl-glycine, GSH) is the most abundant low-molecular-weight thiol in mammalian cells, present at millimolar concentrations. In biochemical research, it is used as a substrate for glutathione-S-transferases and glutathione peroxidases, as a reference compound in redox assay development, as a supplement in cell culture models of oxidative stress, and as a reagent for establishing defined GSH/GSSG ratios in cell-free biochemical systems.
How is L-Glutathione used in redox biology experiments?
In redox research, L-glutathione is used to supplement GSH levels in GSH-depleted cell models (prepared with BSO or DEM), to establish defined redox potentials in reconstituted biochemical systems, and as a substrate for enzymatic activity measurements of GPx, GR, and GST. The GSH/GSSG ratio — established by adding defined ratios of L-glutathione and GSSG — is used to poise reaction systems at specific redox potentials.
What are the stability considerations for L-Glutathione in research?
L-Glutathione is susceptible to oxidation in solution, particularly at alkaline pH and elevated temperature. Stock solutions should be prepared in acidified water (pH 3-4) or neutral buffer containing EDTA to chelate pro-oxidant metal ions. Aliquots should be snap-frozen in liquid nitrogen and stored at -80°C. Researchers should verify the GSH content of each preparation by the DTNB recycling assay before use in quantitative redox experiments.
Is L-Glutathione membrane-permeant in cell-based research?
Unmodified L-glutathione is not efficiently membrane-permeant and primarily affects the extracellular redox environment when added to cell culture media. Intracellular GSH supplementation in research models typically requires cell-permeable derivatives such as glutathione monoethyl ester (GSH-MEE) or glutathione acetamide. Researchers should consider this when designing experiments that require intracellular GSH elevation.
Is L-Glutathione from Elivena for human consumption?
L-Glutathione as supplied by Elivena is a research-grade compound for use in controlled laboratory settings. It is not supplied as a dietary supplement, cosmetic ingredient, or therapeutic product, and is not approved for human administration outside of formally regulated contexts.

Researchers often ask
Is L-Glutathione for human use?
No. L-Glutathione is sold for laboratory research only. It is not for human or veterinary use, and it is not a drug, food or cosmetic.
How do I find the lab report?
Use View COAs on the product page, or search the COA library by compound name. The summary is public; the signed PDF reports are available to signed-in researchers.
Why is purity measured by LC-MS?
LC-MS separates the sample and identifies each component by its mass, so one run confirms identity and measures purity.
When will my order ship?
Orders are dispatched within 24–48 business hours. Regular tracked delivery takes 5 to 10 days and express tracked 3 to 5 days. Regular shipping is free on orders over $200 and express on orders over $400, after discounts.
