Glutathione
Replenishes intracellular glutathione, the master antioxidant that neutralizes oxidative stress, recycles other antioxidants, and supports hepatic phase-II detoxification.
Medically reviewed by Dr. Jonathan Snipes, MD. Last reviewed May 6, 2026.
What It Is
Glutathione is a naturally occurring tripeptide and the body's primary intracellular antioxidant. Levels fall with age, illness, and oxidative load. Oral glutathione is poorly absorbed, so this compounded version is dosed by subcutaneous injection to reach meaningful tissue levels without the larger-volume IV approach.
How It Works
It neutralizes reactive oxygen species inside the cell, recycles vitamins C and E back to their active forms, and supports the liver's phase-II detoxification pathways. Effects are cumulative rather than acute, so consistency matters more than any single dose.
Who It's For
Adults focused on antioxidant support, skin clarity, and detoxification, and those with elevated oxidative load. Also pairs well during rapid weight loss when antioxidant demand rises.
Who Should Avoid It
Avoid in pregnancy and lactation. Use caution in asthma, alongside nitrates or nitroglycerin, and with chemotherapy agents. Flag severe hepatic or renal impairment for provider review. Rare hypersensitivity can occur; stop and seek care for hives, swelling, or breathing difficulty.
