Food supplements are categorized as foods. They are intended to supplement a normal diet. Food supplements may contain a broad spectrum of nutrients or other substances with a specific nutritional or physiological effect. They may be, for instance, vitamins, minerals, trace elements, amino acids, fibre, plants or herbal extracts which are either added individually or as a combination in concentrated form. Food supplements are sold in a dosage form, for instance as tablets, capsules, coated tablets, powders or liquids for intake in small, measured amounts. In contrast to conventional foods, food supplements may come with a recommended intake along with other specific information for consumers, e.g. that they should be stored out of the reach of small children.
