Nutritional supplements in general
x

Dietary supplements deliver nutrients, including vitamins, minerals and amino acids, which may not be consumed in sufficient quantities. They can only be legally sold with a warning statement not to exceed the recommended dose. Vitamins are divided into water-soluble and fat-soluble. Very small amounts are required to support normal physiological function. Microminerals, macrominerals and bioactive food components are equally important. The European Responsible Nutrition Alliance published an information book on the scientific facts relating to the safety and health benefits of vitamins, minerals, and other food components. DRVs are quantitative reference values for nutritional intakes that were set in the EU Food Information for Consumers Regulation 1169/2011 to help consumers make healthy dietary choices. In Europe, surveys have suggested that intakes for several micronutrients are suboptimal. The composition of food supplements remains subject to national legislation, resulting in numerous trade barriers.
