Last month the European Parliament voted for strict regulation of the sale of high dose vitamin supplements. In recent years, consumption of high dose vitamins, minerals and food supplements, in excess of the recommended daily allowance (RDA), has become increasingly popular. Several super-concentrated products with amounts in excess of 12,000% of the RDA are readily available on the market, while the safety of such high doses remains questionable. Under the new Directive approved by European Parliament, manufacturers would have to prove the safety of their products and the maximum limits of these products will be set by EU, with manufacturers barred from selling pills containing higher doses. Whilst the reaction from individual countries of the EU on this Directive is awaited; it may take up to ten years for the new Directive to become effective, and until then, the mega-dose supplements will continue to be available.
