What are food suplements?
The idea behind food supplements, also called dietary or nutritional supplements, is to deliver nutrients that may not be consumed in sufficient quantities. Food supplements can be vitamins, minerals, amino acids, fatty acids, and other substances delivered in the form of pills, tablets, capsules, liquid, etc.1 Supplements are available in a range of doses, and in different combinations.

The EU-funded EURRECA project found inadequate intakes for vitamin C, vitamin D, folic acid, calcium, selenium and iodine. A recent comparison of national surveys showed widespread concern about vitamin D intakes, whereas certain age groups are more likely to have low intakes of minerals. For example, there is concern about adequate intakes of iron amongst teenage girls in Denmark, France, Poland, Germany and the UK.

In some countries (including UK, Ireland, the Netherlands and Sweden) there are already recommendations for certain groups in the population to take a vitamin D supplement, although there are calls for more research.
