RDA, DV, and other recommended intake values
January 1999

These are numerous standards for recommended dosages or intake levels for various types of dietary supplements. They represented by a medley of acronyms including RDA, U.S. RDA, DRI, AI, UL, and EAR. They are proposed by the Food and Nutrition Board of the Institute of Medicine of the National Academy of Sciences (NAS), some in partnership with Health Canada.

DRI is an umbrella term for groups of values, including RDAs, AIs, EARs, and ULs. FDA regulations went into effect in March of 1999 that require labeling of dietary reference intakes (DRI) and which appear as "DV" (Daily Values) on product labels.
