Legal status by country
Is Carnosine legal?
Written by Aaron CuhaReviewed Sep 2026
How Carnosine is classified in the United States, United Kingdom, Australia and Canada, side by side. Each country has its own page with a direct answer, the regulator's approval status and what the classification means in practice.
All four countries, side by side
| Attribute | United States · FDA | United Kingdom · MHRA | Australia · TGA | Canada · Health Canada |
|---|---|---|---|---|
| Status | Not approved | Not approved | Not approved | Not approved |
| Classification | Sold as a supplement | Sold as a supplement | Available as a supplement / complementary medicine | Sold as a supplement |
| Note | A dietary supplement under DSHEA. No FDA evaluation of efficacy and no approved indication. Claims that it treats or prevents any disease are not permitted. | Sold as a food supplement. No medicinal licence and no permitted health claim for ageing. | Available as a complementary medicine. Listed complementary medicines are assessed for safety and quality, not for efficacy. | Sold as a natural health product under an NPN. That number certifies that the product was reviewed for safety and quality, not that any anti-ageing claim was demonstrated. |
US FDA status: Not an approved drug anywhere. Carnosine is sold in the United States as a dietary supplement, which means it is not evaluated by the FDA for efficacy and cannot lawfully be marketed for treating or preventing disease. Its zinc chelate, polaprezinc, is an approved prescription drug for gastric ulcer in Japan, which is a different molecule, a different country and a different indication, and confers no regulatory status on carnosine itself..
