Glutathione IV (1200mg)

Intravenous glutathione infusion delivering 1,200mg of the body's primary endogenous antioxidant. Glutathione is a tripeptide critical to detoxification, free radical neutralisation, and immune cell regulation, with levels that decline naturally with age and are further depleted by environmental stressors.

Glutathione (gamma-L-glutamyl-L-cysteinyl-glycine) is the most abundant intracellular antioxidant in the human body, with its highest concentrations found in the liver, lungs, and kidneys — organs that bear the greatest detoxification burden. It exists in two forms: reduced (GSH), which is the active antioxidant form, and oxidised (GSSG), which accumulates when the molecule has donated electrons to neutralise reactive oxygen species. The ratio of GSH to GSSG is considered a marker of cellular oxidative stress. The 1,200mg IV dose at HADA NO CLINIC delivers glutathione directly into the bloodstream, circumventing the poor oral bioavailability that has historically limited supplementation strategies. When taken by mouth, glutathione is largely broken down by peptidases in the gastrointestinal tract before reaching systemic circulation. Intravenous administration preserves the intact tripeptide structure, allowing it to be taken up by cells throughout the body in its active reduced form. Glutathione is essential for the function of glutathione peroxidase and glutathione S-transferase enzyme families, which together manage phase II liver detoxification — the process by which fat-soluble toxins, drug metabolites, and environmental pollutants are conjugated for excretion. It also regenerates other antioxidants, notably converting oxidised vitamin C (dehydroascorbic acid) back to its active form, creating a synergistic recycling loop that amplifies the antioxidant capacity of both molecules. The 30-minute infusion is well-tolerated by most patients, with occasional reports of a mild sulphur taste during administration — a harmless side effect attributable to the cysteine residue in the molecule. No fasting or special preparation is needed. The treatment is available at both the Koenji and Kojimachi locations seven days a week, with walk-ins accepted. Many patients combine glutathione with a vitamin C infusion in the same visit for a complementary antioxidant effect. The consultation fee is waived from the second IV visit, supporting patients who want regular glutathione maintenance on an ongoing basis.
