An American study questions the effectiveness of top selling nutritional eye supplements.
Only the AREDS and AREDS2 formulas, composed of antioxidants and zinc, proved effective in slowing down the progression of AMD, and only when the disease was in a moderate-to-advanced stage.
Only four products had doses equivalent to AREDS and AREDS 2, four others had doses that were much too weak, and four added vitamins, minerals and superfluous herbal extracts. In addition, none of them indicated for which types of patients a nutritional supplement could be effective.
