title: [Update on reassessment of dietary reference intakes (DRIs) for vitamin D].
abstract: The latest clinical studies show that vitamin D has many health promoting functions. However, the current dietary reference intakes (DRIs) of vitamin D is too low. In particular the maximum tolerable intake (UL) of vitamin D is too low, which hampers the clinical use of vitamin D as an nutrient and must be re-assessed. We reviewed the average requirement (EAR) and the recommended intake (RNI) of vitamin D in children, adults, elderly and pregnant and parturient women, and encouraged to increase the recommended intake of vitamin D. We also reviewed the risk of high-dose vitamin D intake and suggested to raise the maximum tolerable intake (UL) made by American CRN. Finally, we propose that Chinese Nutrition Society will consider to increase the UL of vitamin D from 20 microg to 50 microg.
