Glutathione

other

Antioxidant (oral/IV wellness)

Research status · Dietary supplement

Available as an oral supplement; IV glutathione is offered in wellness/aesthetic settings and is not FDA-approved for skin lightening or anti-aging. Evidence for many marketed uses is limited.

Glutathione is the body's major intracellular antioxidant. Oral supplements exist; IV glutathione is marketed for skin and 'detox' but is not FDA-approved for those uses, and safety of unregulated IV products is a concern.

How it works

A tripeptide antioxidant that neutralizes reactive oxygen species and supports detoxification enzymes.

Commonly discussed use cases

  • Antioxidant support (discussed)
  • Skin brightening (marketed, unapproved)

Supposed / potential benefits

  • Antioxidant role is real biologically; marketed cosmetic benefits are not well established

Common side effects

  • Generally well tolerated orally
  • IV: infusion reactions; unregulated IV products carry risk

Warnings & contraindications

  • IV glutathione is not FDA-approved for skin lightening/anti-aging
  • Regulators have warned about unregulated injectable skin-lightening products

Typical timing considerations

Oral daily per product; IV sessions clinic-scheduled. Follow guidance.

Administration route

Oral, or IV/injection (clinic)

Questions to ask your clinician

  • Is there evidence for the benefit I'm after?
  • Is oral sufficient vs IV, and is the IV product reputable?

Track this in Reta

Beta members get a ready-made tracker for Glutathione — schedule, dose log, injection-site rotation, reminders, and check-ins — for organizing a clinician-directed routine. Personal tracking is available to everyone during the Public Beta.

Reta is a tracking and education tool — not a medical provider. Nothing here is a diagnosis, treatment, prescription, or dosing recommendation. Peptides and medications should only be used under the direction of a licensed clinician. Talk to a qualified clinician before starting, stopping, combining, or changing anything. Many compounds below are not FDA-approved for human use; some are investigational or sold through unregulated channels where purity and dosing are not guaranteed.
