Creatine:new health claim for sportspeople over the age of 55?

摘要

Creatine is a well-characterized food ingredient described by the European Food Safety Authority (EFSA) as a 'non-essential nitrogenous organic acid that occurs in vertebrates and that is also synthesised in the human body from L-arginine, glycine andL-methionine. Approximately 95% of the creatine pool in the body is located in skeletal muscle'. Because of these features, creatine is a key ingredient for food supplement formulations targeted at sportspeople. From a regulatory viewpoint it is permitted as a food ingredient throughout the EU, even if its use is not fully harmonized. Indeed, the maximum permitted daily intake varies among different Member States (e.g., in Italy up to 6 g is permitted for sportspeople).
