The European Union could have to reform its directive on market approvals for food supplements (2002/46/EC) after a formal opinion from the European Court of Justice.

The court's advocate general has claimed the law breaks EU treaty commitments on fair trade by failing to benchmark the addition of new supplements to an approved supplements list for pan-EU sales.

It also, said Leendert Geelhoed, illegally fails to establish a solid procedure for new market approvals. The full ECJ usually formally approves the opinions of its advocate generals. Other claims against the law by British plaintiffs the Alliance for Natural Health, Nutri-Link Ltd, the National Association of Health Stores and Health Food Manufacturers Ltd, were dismissed.
