Overview

Glutathione is a tripeptide made of glutamate, cysteine, and glycine that is a major intracellular antioxidant and a participant in detoxification pathways. It is available as a supplement and is sometimes administered parenterally in clinical settings; this entry is educational context only.

How it’s thought to work

  • Commonly cited as a primary intracellular antioxidant that neutralizes reactive oxygen species.
  • Reported to serve as a cofactor for glutathione peroxidase enzymes.
  • Associated with phase-II detoxification and conjugation reactions in the literature.
  • Described as helping regenerate other antioxidants such as vitamin C.

Researched uses

  • Oxidative-stress endpoints in research settings
  • Studied in liver and detoxification contexts
  • Explored in the literature for skin and dermatologic endpoints

Commonly cited protocol

Typical doseDosing is expressed in milligrams and varies widely by route; parenteral figures are cited in the hundreds of mg per session in some settings
FrequencyVaries by route and setting
RouteOral or liposomal supplement; sometimes given intravenously or intramuscularly in clinical settings
NotesWhen given IV or IM it is dosed in milligrams by a clinician, so consumer insulin-syringe unit math via micrograms does not apply.

Reconstitution

Oral forms are taken by mouth, and parenteral forms are dosed in milligrams by a clinician, so consumer insulin-syringe unit conversions do not apply.

Cautions

  • Oral forms are sold as supplements; injectable use is a clinical procedure that should involve a licensed provider.
  • Compounded injectable products have been the subject of safety and sterility concerns.
  • Supplement quality and bioavailability vary widely by formulation.
  • Presented for educational context only, not as medical advice.
