“Background The introduction of the Nutrition and Health Claims Regulation in 2006 has provided focused guidelines across the European Union for the use of nutrition/health claims, for example “”the maintenance of endurance performance”" for specific nutrition products. This Regulation aims to ensure that any claim made on foods’ labelling, presentation or marketing in the European Union is clear, accurate and based on evidence accepted by the scientific community.
