DRI Dietary Reference Intakes Calcium Vitamin D
THE COMMITTEE’S OUTCOMES
An assumption in developing the DRIs for calcium is that they are predicated on intakes that meet requirements for vitamin D; similarly, DRIs for vitamin D rest on the assumption of intakes that meet requirements for calcium.
Dietary Reference Intakes for Calcium
DRIs for calcium were established as EARs and RDAs except for infants up to 12 months of age for whom AIs were specified. The DRIs for calcium are shown in Table S-1.
