Alphabet Soup What Are DRIs

Dietary Reference Intakes (DRIs). Daily nutrient recommendations—expressed as RDAs or AIs—based on age and gender; set at levels to decrease the risk of chronic disease.

Recommended Dietary Allowances (RDAs). Recommended daily levels of nutrients to meet the needs of almost all healthy individuals in a specific age and gender group; used when there's scientific consensus for a firm nutrient recommendation.

Adequate Intakes (AIs). Similar to RDAs, and used for nutrients that lack sufficient scientific evidence to determine a firm RDA.

Tolerable Upper Intake Level (UL). Not a recommendation; maximum intake that most likely won't pose risks for health problems for almost all healthy people in that age and gender group.

Daily Values (DVs) for nutrients aren't DRIs, although they are based on RDA values from the past. DVs are used for food labeling.
