Your protocol

How Glutathione is prescribed.

Who it's for
  • Adults focused on antioxidant support and detoxification
  • Patients whose physician wants a higher glutathione level than oral supplements reach

Your physician decides whether Glutathione is appropriate for you after reviewing your intake and labs.

Directions & duration

Inject 0.41 mL (41 units) subcutaneously three times per week.

Cycle. Ongoing at your physician's direction, commonly a few times per week.
Ready for more? When you're ready for more, ask your physician to move you up to the next strength. Approved steps are charged at the price difference and applied to your next fill.
Directions shown are the pharmacy's standard for this preparation. Your prescription label is the final word.
What's included

The science

How Glutathione works, and what the research shows.

How it works

Glutathione is the body's principal intracellular antioxidant — a tripeptide (glutamate-cysteine-glycine) that neutralizes reactive oxygen species, regenerates vitamins C and E, and serves as the substrate for the liver's phase II detoxification enzymes.

Levels decline with age and oxidative stress; injection bypasses the poor oral bioavailability of glutathione taken by mouth.

Clinical evidence
  • Glutathione's biochemistry is textbook-established, and deficiency states are well documented.

  • Clinical trials of supplemental glutathione are smaller: studies show oral absorption is poor, while injectable and IV administration reliably raises levels; small human trials in skin and neurological conditions have produced mixed results.

  • Injectable glutathione is prescribed as supportive therapy at physician discretion.
