L-Glutathione (Reduced) — Mechanism & Specifications

L-Glutathione (γ-L-glutamyl-L-cysteinyl-glycine) is the most abundant intracellular thiol antioxidant in mammalian cells. It is central to phase-II detoxification, redox homeostasis and free-radical neutralization. Provided in the reduced GSH form for stability.

Quality & release criteria

Every lot of L-Glutathione (Reduced) is released only after passing reverse-phase HPLC (≥ 99% area purity at 220 nm against a reference standard), ESI mass spectrometry confirmation of molecular weight, and Limulus Amebocyte Lysate (LAL) endotoxin testing below 0.5 EU/mg. The lot-specific Certificate of Analysis is provided with the order and available on request before purchase.

FAQ

L-Glutathione (Reduced) — Frequently asked questions

What is L-Glutathione?
L-Glutathione (γ-Glu-Cys-Gly) is the most abundant intracellular thiol antioxidant in mammalian cells. It is central to phase-II detoxification, redox homeostasis and free-radical neutralization. Provided in the reduced GSH form for stability. CAS 70-18-8.
How is L-Glutathione typically used?
Common subcutaneous protocols use 200-600mg per dose, 1-3 times per week. A 1500mg vial reconstituted with 10mL bacteriostatic water yields 150mg per mL — so 1mL delivers 150mg, 2mL delivers 300mg. IV protocols at higher doses require clinical setting.
How is L-Glutathione tested?
Each Glutathione lot is HPLC-tested to ≥99% purity, ESI-MS verified against the theoretical 307.32 Da molecular weight, and tested for endotoxins. ISO 17025-accredited third-party labs perform the testing.
How do I store L-Glutathione?
Lyophilized Glutathione is stable at -20°C for 24+ months. After reconstitution, store refrigerated at 2-8°C and use within 14-21 days. The reduced GSH form oxidizes over time once in solution.
