摘要

Following a request from the European Commission, the Panel on Dietetic Products, Nutrition and Allergies was asked to provide a scientific opinion on a list of health claims pursuant to Article 13 of Regulation (EC) No 1924/2006. This opinion addresses the scientific substantiation of health claims in relation to L-theanine from Camellia sinensis (L.) Kuntze (tea) and improvement of cognitive function, alleviation of psychological stress, maintenance of normal sleep and reduction of menstrual discomfort. The scientific substantiation is based on the information provided by the Member States in the consolidated list of Article 13 health claims and references that EFSA has received from Member States or directly from stakeholders. The food/constituents that are the subject of the health claims are Camellia sinensis (L.) Kuntze (tea) and L-theanine. The Panel considers that while Camellia sinensis (L.) Kuntze (tea) is not sufficiently characterised in relation to the claimed effects, L-theanine from Camellia sinensis (L.) Kuntze (tea) is sufficiently characterised.
