Glutathione IV

Glutathione is a tripeptide (cysteine + glycine + glutamic acid) that serves as the body's primary intracellular antioxidant and a key cofactor in phase-II liver detoxification pathways. Oral glutathione has poor bioavailability — it is broken down in the gut before reaching cells.³ IV glutathione delivers intact molecules directly to the bloodstream, raising serum and tissue concentrations more reliably.

How it works

Glutathione neutralizes reactive oxygen species (ROS), recycles other antioxidants like vitamin C and E, and supports the glutathione S-transferase pathway that conjugates and excretes lipid-soluble toxins. Endogenous production declines with age and is depleted under chronic stress, infection, or exposure to oxidants.

What the evidence supports — and does not

Glutathione has well-established roles in clinical medicine — N-acetylcysteine (a precursor) is the standard antidote for acetaminophen overdose, for example. IV glutathione has small-trial evidence in Parkinson's disease¹, hepatic conditions², and oxidative-stress states. Cosmetic and general-wellness applications (skin brightening, energy, recovery) are largely supported by patient-reported outcomes and case series rather than large RCTs.

Who it is for

Healthy adults seeking antioxidant support, recovery from intensive training, or as an adjunct to other wellness protocols. Often combined with vitamin C and B-complex in cocktail-style IVs. Not a treatment for any specific FDA-approved medical condition outside of established clinical applications.

What to expect

• 30–60 minute IV; can be combined with other IV nutrients.
• Common side effects: mild nausea, flushing, headache, transient pulmonary symptoms. Generally well-tolerated.
• Acute brightening / energy effects often reported within 24 hours; cumulative effects develop over a series.
• Typical protocols: 600–2000 mg per session, often weekly.
