Written by Aaron CuhaReviewed Sep 2026
Direct answer
Yes. Ursodeoxycholic acid is an approved medicine in Canada, classified as "Health Canada approved, prescription only". Approval covers its labeled indication and it is supplied on prescription, not over the counter. Products labeled "research use only" fall outside that approval and the label does not make human use lawful. On the evidence, 1 human study is cited on its profile.

What this means
- 01
Health Canada has approved Ursodeoxycholic acid for at least one labeled indication, so a pharmaceutical-grade product exists in Canada and is dispensed on prescription.
- 02
Approval is indication-specific. Uses outside the label are a clinical decision for a prescriber, not something the approval itself authorizes.
- 03
Unlicensed online vials, including those labeled "research use only", are not the approved product and are not covered by the approval.
What Ursodeoxycholic acid is
An approved bile acid with a genuine mechanism in mitochondrial protection. It failed mouse lifespan testing, and its randomised trial in Parkinson's disease is the more informative result.
Ursodeoxycholic acid is a naturally occurring bile acid, approved for primary biliary cholangitis and gallstone dissolution, that turned out to have effects beyond the liver. It stabilises mitochondria, reduces endoplasmic reticulum stress and inhibits apoptosis, which made it a candidate for neurodegeneration and for ageing.
Mechanism: A hydrophilic secondary bile acid. In cholestatic liver disease it displaces more toxic hydrophobic bile acids from the bile acid pool and stimulates biliary secretion, which is the basis of its approval.
Regulatory history: FDA-approved for primary biliary cholangitis and for gallstone dissolution in selected patients. Not approved for Parkinson's disease or any ageing indication.
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 Ursodeoxycholic acid 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.
