Is Taurine legal in the United Kingdom?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Taurine can be sold in the United Kingdom as a supplement or cosmetic ingredient, classified as "Sold as a supplement". That is not drug approval: MHRA has not evaluated any health claim, and injectable or "research use only" versions fall outside supplement rules, so that label does not make human use lawful. On the evidence, 1 human study is cited on its profile.

What Taurine is
A 2023 paper in Science proposed taurine decline as a driver of ageing. Two separate 2025 papers, one from the NIA's own programme, report that it does not decline.
Taurine is an amino sulfonic acid found throughout the body and abundant in the diet. In 2023 a paper in Science reported that taurine declines with age across species and that supplementing it extended lifespan in mice and improved health markers in monkeys, which made it briefly the most discussed longevity compound in the world.
Mechanism: Involved in bile salt conjugation, osmoregulation, calcium handling and mitochondrial protein synthesis. The proposed geroprotective mechanism runs through reduced cellular senescence, improved mitochondrial function and reduced inflammation, and is drawn from the animal work rather than demonstrated in people.
Regulatory history: Sold as a dietary supplement. Not an approved drug.
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 Taurine 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.
