“Daily Value (DV)” is a term used and set by the FDA. It replaced the FDA's term “US RDA”. The terminology change was the result of finalization of the labeling regulations portion of DSHEA (Dietary Supplement Health and Education Act) that mandated using the Supplement Facts Box on supplement labels.

The DVs are the FDA’s version of the Institute of Medicine's recommended intakes for vitamins and minerals. The Institute of Medicine and its Food and Nutrition Board are part of the National Academy of Sciences.

The Institute of Medicine sets levels of RDAs (Recommended Dietary Allowances) for vitamins and minerals that are broken down by age and gender. These RDAs are generally lower than DVs and are used by the Federal government for planning of food programs like school lunches, etc.

The Institute of Medicine has been releasing new reports called Dietary Reference Intakes (DRIs). The report sets recommended dietary allowance (RDA), adequate intake (AI) and upper intake levels (UL) for vitamins and minerals. So far the FDA has not revised the Daily Values to reflect any of these changes, and it is the DVs only that are used on supplement labels and of which consumers need be aware.
