The US comes first because most people ask about it. Each country has its own page. It names the agency, the law or rule, and what the legal category means in real life.
All four countries, side by side
| What we list | United States · FDA | United Kingdom · MHRA | Australia · TGA | Canada · Health Canada |
|---|---|---|---|---|
| Status | Not approved | Not approved | Not approved | Not approved |
| Legal category | Sold as a supplement | Sold as a supplement | Available as a supplement / complementary medicine | Sold as a supplement |
| Note | A dietary supplement under the US supplement law. The FDA has not checked whether it works, and it has no approved use. Sellers may not claim it treats or prevents any disease. | Sold as a food supplement. Not licensed as a medicine, and sellers may not make health claims about ageing. | Available as a complementary medicine. Listed complementary medicines are checked for safety and quality, not for whether they work. | Sold as a natural health product with a Natural Product Number (NPN). That number means the product was reviewed for safety and quality. It does not mean any anti-ageing claim was proven. |
| Agency | Check FDA directly | Check MHRA directly | Check TGA directly | Check Health Canada directly |
US FDA status: Not an approved drug anywhere. In the United States carnosine is sold as a dietary supplement. That means the FDA has not checked whether it works, and it cannot legally be sold as treating or preventing disease. Carnosine bound to zinc, called polaprezinc, is an approved prescription drug for stomach ulcers in Japan. That is a different molecule, in a different country, for a different use, and it gives carnosine itself no legal standing.. Reviewed Sep 2026.

The full Canada answerCarnosine in sport and the military
Whether Carnosine is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status. Before you compete or get tested, look up Carnosine 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.

- Global DRO (check a named product)
- USADA (US athletes)
- Operation Supplement Safety (US service members)
