Is Glutathione legal in the United States?
Glutathione can be sold in the United States as a supplement or cosmetic ingredient, classified as "Permitted as a dietary supplement; injectable not FDA-approved".

What Glutathione is
The body's master intracellular antioxidant tripeptide, used to support redox balance, detoxification, and skin, with mixed clinical evidence for supplementation.
Glutathione is a tripeptide of glutamate, cysteine, and glycine that is the principal antioxidant inside human cells and a key cofactor for detoxification enzymes. Its biochemistry is very well established, but oral bioavailability is poor and clinical evidence for supplemental glutathione (oral, liposomal, nebulized, or intravenous) is mixed.
Mechanism: Neutralizes reactive oxygen species directly and via glutathione peroxidase, recycles other antioxidants, and conjugates toxins for elimination through glutathione S-transferases.
Regulatory history: Not an approved drug; sold as a supplement (injectable forms flagged by FDA)
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for Glutathione at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
