Glutathione is a naturally occurring tripeptide (glutamate-cysteine-glycine) and a major intracellular antioxidant. It is sold in the U.S. as a dietary-supplement ingredient and as a compounded preparation, and is studied in the research literature. Materials labeled for laboratory or research use are not FDA-approved finished drug products.
Regulatory status: As of 2026, glutathione is not approved by the FDA as a stand-alone finished drug product; it is marketed as a supplement ingredient and used in pharmacy compounding, and the FDA has warned about certain compounded/injectable glutathione products.
