How Glutathione Works

Glutathione is the most abundant intracellular thiol antioxidant, serving as the primary cellular defense against oxidative stress. It directly scavenges reactive oxygen species and serves as a cofactor for glutathione peroxidases and glutathione-S-transferases. The reduced thiol group on its cysteine residue donates electrons to neutralize ROS and electrophilic toxins. Glutathione also maintains vitamins C and E in their reduced (active) forms, regulates the nitric oxide cycle, and is essential for immune cell function, particularly T-lymphocyte proliferation.

Frequently Asked Questions

Glutathione (CAS: 70-18-8) is a research compound, with a molecular weight of 307.32 Da in the Anti-Aging / Longevity category. Glutathione is the most abundant intracellular thiol antioxidant, serving as the primary cellular defense against oxidative stress. It directly scavenges reactive oxygen species and serves as a cofactor for glutathione peroxidases and glutathione-S-transferases. Researchers commonly investigate Glutathione for Oxidative stress and antioxidant defense, Detoxification and xenobiotic metabolism, Immune function and T-cell activity. Every vial from MiPeptidos includes batch-specific analytical documentation.
Glutathione is available in 2 sizes (400mg, 1500mg), so reconstitution volume depends on which vial you have. For the 400mg size, add 2-5mL of bacteriostatic water; for the 1500mg size, use 2-5mL. Always let the vial warm to room temperature first, inject the water slowly along the vial wall, and swirl gently — never shake. Store reconstituted Glutathione at 2-8°C and use within 30 days. MiPeptidos carries bacteriostatic water in 3mL and 10mL vials.
Glutathione and NAD+ are both fundamental cellular molecules, but they serve different roles. Glutathione (a tripeptide: Glu-Cys-Gly, 307 Da) is the primary intracellular antioxidant that neutralizes ROS via glutathione peroxidase and conjugates toxins for excretion via glutathione S-transferases. NAD+ is a coenzyme for metabolic redox reactions and sirtuin activation. Glutathione protects against oxidative damage; NAD+ drives energy metabolism. MiPeptidos carries both for comprehensive cellular health research.
Store lyophilized Glutathione at -20°C for maximum long-term stability — properly stored, it remains potent for 24+ months. Once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use within 30 days. In research applications, Glutathione has a reported half-life of ~10-15 minutes IV; intracellular half-life is hours, which informs dosing frequency and protocol design. Avoid repeated freeze-thaw cycles and protect from direct light. MiPeptidos ships every order with cold-chain packaging to maintain integrity during transit.
Every Glutathione order from MiPeptidos includes a batch-specific Certificate of Analysis. Our current batch (HR-GLTT-2600315, tested March 27, 2026) shows 99.3% purity by HPLC, mass spectrometry confirmation at 307.32 Da, endotoxin levels below 0.1 EU/mg, and passing sterility per USP <71>. This level of documentation ensures you can verify compound identity and purity before beginning your research. MiPeptidos also offers bulk pricing on orders of 50+ vials — contact info@mipeptidos.com.
