Research Context
Glutathione is the most abundant non-protein thiol in mammalian cells and the substrate for antioxidant enzyme systems including glutathione peroxidase and glutathione S-transferase. The reduced form (GSH) and its oxidised disulfide (GSSG) form a redox couple, and the GSH:GSSG ratio is one of the most widely used markers of oxidative status in cell biology.
In the literature, glutathione is studied for its role in cellular defence against reactive oxygen species, in phase II detoxification reactions, and in modulating the efficacy and toxicity of chemotherapeutic agents. Its clinical history includes use as an adjunctive agent in chemotherapy research, where published work examines whether it reduces the neurotoxicity associated with platinum-based compounds.
For laboratory use, it is a standard reagent in oxidative-stress assays, GSH/GSSG ratio measurements, glutathione-S-transferase and peroxidase activity assays, and protein-protection studies. The reduced form is the correct reagent for these assays, which is why the oxidation state is stated explicitly on this listing.
The 1500 mg quantity suits laboratories preparing their own assay buffers at defined concentrations rather than working from small analytical aliquots.
Selected Reading & Research Notes
- Glutathione redox biology literature — Establishes the GSH/GSSG couple as the primary thiol redox buffer in mammalian cells and a standard oxidative-stress marker.
- Adjunctive glutathione chemotherapy research — Examines glutathione in the context of platinum-compound toxicity and antioxidant status in treated patients.

Laboratory Handling
Prepare working solutions in water or the buffer specified by your assay. Reduced glutathione oxidises in solution, particularly with aeration or at alkaline pH, so solutions should be prepared fresh and kept cold. The bulk powder should be kept desiccated at −20 °C away from light and allowed to reach room temperature before opening.
How It Differs From Related Compounds
Glutathione is a small tripeptide reagent rather than a receptor-ligand peptide: it is water-soluble at high concentration, is used as an assay substrate and antioxidant standard, and its oxidation state is analytically critical. It is not interchangeable with any other item on this catalogue.

Customer Reviews
Good, bulk option would be nice
I use a lot so the 1500mg vials add up. A bigger size or bulk discount would help. The quality is there though.

Lab switched here
Our lab moved all glutathione orders here. Properly reduced, stable, consistent. No more wasting money on oxidized product.
Luke M.
Great quality
Excellent product and my models show the expected effects.
Rach L.
Consistent results
My results are consistent across replicates. The quality directly impacts data quality and this stuff is good.

Great quality
Giving me clean, consistent results. The 1500mg size is practical and lasts a good while.

Best I've used
Tried 3 suppliers and this is the best. The ratio is excellent. Results show exactly what they should.
Mel J.
Verified independently
Ran my own HPLC and purity matches the COA. Genuine reduced glutathione, not degraded. Consistent across multiple orders.

Fast shipping to Quebec City
Three days, properly packaged. Tested at full reduced capacity. COA was available online before I even got the package.

Reliable Canadian source
No more importing from the US. Same or better quality, faster shipping, better documentation.

Wish it was a bit cheaper
Glutathione is glutathione, and this is good quality. Not the cheapest but worth it for something that actually works.
Ben G.
Stable and fresh
Glutathione goes bad easily but this arrived properly sealed and has stayed stable. Handled correctly. Good stuff.

Properly reduced, not oxidized
This is a big deal. A lot of glutathione you buy is already oxidized and basically useless. Tested this and it's predominantly in the reduced form.
