It emerges from the judgment of the Court of Justice, of 12 July 2005, in Joined Cases C-154/04 and C-155/04, Alliance for Natural Health and Others, that the relevant provisions of the Directive on the approximation of the laws of the Member States relating to food supplements, which prohibit the marketing in the Community of food supplements containing vitamins and minerals not included on the positive lists, are not invalid by reason of an infringement of the principle of subsidiarity or of the principle of proportionality. The objective pursued by the provisions cannot be satisfactorily achieved by action taken by the Member States alone and requires action to be taken by the Community. What is more, they are measures appropriate for achieving the objective which they pursue and, given the obligation of the Community legislator to ensure a high level of protection of human health, they do not go beyond what is necessary to attain that objective.
