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.
最新的临床研究表明，维生素D具有多种促进健康的功能。然而，目前维生素D的膳食参考摄入量（DRIs）过低。特别是维生素D的最大可耐受摄入量（UL）过低，这阻碍了维生素D作为一种营养素的临床应用，必须重新评估。我们回顾了儿童、成年人、老年人以及孕妇和产妇维生素D的平均需求量（EAR）和推荐摄入量（RNI），并鼓励增加维生素D的推荐摄入量。我们还回顾了高剂量摄入维生素D的风险，并建议提高美国CRN制定的最大可耐受摄入量（UL）。最后，我们建议中国营养学会考虑将维生素D的UL从20微克提高到50微克。
