The RDA is a precise scientific standard. The Daily Value is a simplified benchmark derived from RDAs and used for general food labelling, often based on a 2000-calorie diet.
In the United States, they are set by the National Academies of Sciences, Engineering, and Medicine. In the UK and Europe, similar values (Dietary Reference Values, Nutrient Reference Values) are set by government health agencies and expert committees like the Scientific Advisory Committee on Nutrition (SACN).
