L-Glutathione 1500mg Peptide

L-Glutathione 1500mg – High-Purity Research Peptide

L-Glutathione (GSH) is a naturally occurring tripeptide composed of glutamic acid, cysteine, and glycine. It serves as one of the body’s primary antioxidants, supporting detoxification pathways, immune response, and protection against oxidative damage. Supplied in lyophilised (freeze-dried) form to preserve stability, this compound is verified at ≥ 99.1 % purity (HPLC-tested) and provided with full Certificates of Analysis (COAs).

What is L-Glutathione?

L-Glutathione is the biologically active (levo) form of glutathione found in living cells. It plays a central role in redox balance by donating electrons to neutralize reactive oxygen species (ROS), regenerating antioxidants such as vitamin C and E, and detoxifying harmful compounds through enzymatic conjugation.

Unlike consumer supplements, all products supplied by Bluewell Peptides are strictly intended for laboratory research use only and include full COA verification for transparency.

Research Applications of L-Glutathione

L-Glutathione has been investigated in preclinical and laboratory studies for its potential influence on:

• Oxidative Stress Regulation – Supports reduction of reactive oxygen species and lipid peroxides.

• Detoxification Processes – Central to glutathione S-transferase activity and phase II metabolism.

• Cellular Repair and Protein Protection – Maintains thiol redox status and restores oxidized enzymes.

• Liver and Skin Research – Studied for hepatoprotective and melanin-modulating effects in experimental models.
