Scientific Opinion on the substantiation of a health claim related to a combination of Paullinia cupana Kunth (guarana) and Camellia sinensis (L.) Kuntze (green tea) extracts and reduction of body weight pursuant to Article 13(5) of Regulation (EC) No 1924/2006

Following an application from Nutrilinks Sarl, submitted pursuant to Article 13(5) of Regulation (EC) No 1924/2006 via the Competent Authority of Cyprus, the Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver an opinion on the scientific substantiation of a health claim related to a combination of Paullinia cupana Kunth (guarana) and Camellia sinensis (L.) Kuntze (green tea) extracts and reduction of body weight. The Panel considers that the food constituent which is the subject of the health claim is sufficiently characterised. The claimed effect, reduction of body weight, is a beneficial physiological effect for overweight subjects. One human intervention study from which no conclusions could be drawn for the scientific substantiation of the claim was provided by the applicant. The Panel concludes that a cause and effect relationship has not been established between the consumption of a combination of Paullinia cupana Kunth (guarana) and Camellia sinensis (L.) Kuntze (green tea) extracts and a reduction in body weight.
