Sammanfattning

Health claims for food are harmonized in the European Union by the European Food Safety Authority (EFSA). Nutritional supplements containing vitamin A or B, docosahexaenoic acid or zinc are allowed to state in their marketing that they preserve vision. This decision is based only on studies of cell metabolism and deficiency diseases and not on clinical interventions. A preventive effect on progression of age-related macular degeneration has however been proven with the AREDS-formula, with an absolute risk reduction for severe visual loss of 6% in certain groups. This treatment may however be associated with considerable side effects. Only 2 of the 25 nutritional supplements for preserved vision available on the Swedish market today follows the AREDS-formula. The present marking of ocular nutritional supplements might therefore be misleading for the customer.
