In the EU: the register of health claims
Claim not authorised in the EU
- The carnosine claims for "endurance," "muscle strength," and "heart" were not authorised (2011 opinion).
In the EU, only health claims whose evidence has been assessed by the European Food Safety Authority (EFSA) and authorised by the European Commission may be used on food. “Not authorised” means the evidence for that claim was not established under EU standards — not that the ingredient is dangerous.
