Is Ursolic acid legal in the United Kingdom?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Ursolic acid can be sold in the United Kingdom as a supplement or cosmetic ingredient. Its legal category is "Sold as a supplement". That is not approval as a drug. MHRA has not checked any health claim made for it. Versions you inject, and "research use only" versions, fall outside supplement rules, so that label does not make them legal to use in people. On the evidence, 1 completed human trial is cited on its profile.

A "research use only" label on a vial does not make it legal to use on people.

What this means
- 01
Ursolic acid can be sold in the United Kingdom as a supplement, food or cosmetic ingredient, under the legal category above. It has no approval as a drug.
- 02
Being sold as a supplement means MHRA has not checked any health claim. The makers are responsible for safety and labels, and quality varies from product to product.
- 03
Versions you inject, and "research use only" versions, are not supplements. That label does not make them legal to use in people, and anything you inject falls under the rules for medicines.
What Ursolic acid is
It did not change lifespan at the dose tested in mice, in the same test where acarbose made male mice live 16 to 17 percent longer. The whole human record is one eight-week study in 16 men. Body fat percentage went down. Lean tissue, like muscle, did not change.
Ursolic acid is a plant compound found in apple peel, rosemary and holy basil. It is sold almost entirely because of one line of mouse studies from a single lab.
How it works: It is a plant compound from a family called triterpenoids. The muscle idea comes from lab work suggesting it boosts insulin and IGF-1 signals in muscle.
Approval history: Sold as a dietary supplement. Not an approved drug and not approved to prevent or treat anything.
How MHRA treats this kind of product
Licenses medicines for sale in the UK. A compound without a licence to be sold (a marketing authorisation) is an unlicensed medicine. The law only lets it reach people through a prescriber, under the specials scheme (unlicensed medicines made for one patient's needs). It cannot be sold as a research product.
The legal category above is how The Longevity Archive reads Medicines and Healthcare products Regulatory Agency listings for Ursolic acid on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.
Ursolic acid in sport and the military
Whether Ursolic acid is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in the United Kingdom. Before you compete or get tested, look up Ursolic acid by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
