Daily Value

The percent Daily Value (% DV) reported on Dietary Supplement (DS) product labels is based primarily on the 1968 Recommended Dietary Allowances (RDAs)1. Specifically, the % DVs for nutrients listed on the required labels for DS are based on the highest of the 1968 RDAs for persons four years of age and older, excluding pregnant and lactating women. The reference values used for labeling vitamins and minerals are termed the Reference Daily Intakes (RDIs), with Daily Reference Values (DRVs) established by the FDA for macronutrients, sodium, and potassium2. Additional regulations later added RDIs for vitamins and minerals from the 1989 RDAs3 and established RDIs for vitamin K, selenium, manganese, chromium, molybdenum, and chloride4. The % DV is based on the Food and Drug Administration (FDA) reference values and a daily 2,000 calorie diet.

The current reference values used as the basis for the % DV reported on the Supplement Facts Panel are shown in the tables below. The first table provides the Daily Value nutrient references, based on a 2,000 calorie diet for adults and children over 4 years. The second table includes the Daily Values for infants, children less than 4 years of age, and pregnant and lactating women. A good additional source of information about nutrition labeling is the background section of Food Labeling: Revision of Reference Values and Mandatory Nutrients, Federal Register, Vol. 72, No. 212, November 2, 2007 PDF documents are best viewed with the free AdobeĀ® Reader.
