Following an application from Hassia Mineralquellen GmbH & Co KG, submitted for authorisation of a health claim pursuant to Article 13(5) of Regulation (EC) No 1924/2006 via the Competent Authority of Germany, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver an opinion on the scientific substantiation of a health claim related to Rosbacher drive® and increased attention. The Panel considers that Rosbacher drive®, which contains natural mineral water plus grape juice, lemon juice, pomegranate juice, elderberry juice, isomaltulose, sucrose, fructose syrup, caffeine, ascorbic acid and natural flavourings, is sufficiently characterised. The claimed effect, increased attention, is a beneficial physiological effect. The single study which was carried out with Rosbacher drive® was an open-label, non-randomised sequential study and the study did not report on any outcomes of attention. No conclusions can be drawn from this study for the scientific substantiation of the claim. The Panel concludes that a cause and effect relationship has not been established between the consumption of Rosbacher drive® and increased attention.
