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 MHRA treats this kind of product
Licenses medicines for the UK market. A compound without a marketing authorisation is an unlicensed medicine, which can only lawfully be supplied for human use through a prescriber under the specials scheme, not sold as a research product.
The classification above is the The Longevity Archive reading of Medicines and Healthcare products Regulatory Agency 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.
