Direct answer
Taurine can be sold in Canada as a supplement or cosmetic ingredient, classified as "Sold as a supplement". That is not drug approval: Health Canada 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 Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch 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.
