L-Glutathione 1500MG — Tripeptide Antioxidant
L-Glutathione 1500MG — Tripeptide Antioxidant
L-Glutathione is the reduced form of glutathione, a naturally occurring tripeptide of glutamate, cysteine and glycine. Its cysteine residue carries a free thiol group, which is what makes it a redox-active molecule and also what makes it sensitive to oxidation in solution.

Storage and handling
- Dry powder: store at −20 °C, sealed, protected from light and moisture.
- Bring the sealed vial to room temperature before opening — lyophilized powder is hygroscopic and draws moisture onto a cold surface.
- After reconstitution: refrigerate at 2-8 °C, protect from light, and avoid repeated freeze-thaw cycles.
- The free thiol oxidises readily in solution — prepare fresh, keep the container tightly closed, and minimise exposure to air.
What you need to reconstitute it
Material is supplied dry and has to be brought into solution before use. Bacteriostatic Water 20 mL is the standard solvent and is sold separately — step-by-step procedure in the reconstitution guide, and a comparison of solvents in bacteriostatic water vs sterile water.
Documentation
Every batch is third-party tested: HPLC for chromatographic purity, mass spectrometry for identity. New to batch documents? See how to read a COA, what 99% purity actually means and net peptide content vs gross weight.
