Vitamin D is an essential nutrient for skeletal mineralization and maintenance of bone mass. Most healthy individuals can meet their vitamin D requirements through dietary means, modest supplementation and solar exposure for short periods of time. The serum level of 25OHD that determines adequacy is 20 ng/ml, which corresponds with consumption of 6-800 IU of vitamin D per day, according to the Institute of Medicine review. There is still debate about whether higher doses of vitamin D are required for treating patients with osteoporosis.
维生素 D 是骨骼矿化和维持骨量所必需的营养物质。大多数健康个体可以通过饮食、适度补充和短时间的阳光暴露来满足其维生素 D 的需求。根据医学研究所的评估，决定充足性的血清 25OHD 水平为 20ng/ml，这相当于每天摄入 6-800IU 的维生素 D。目前仍存在争议，即对于骨质疏松症患者是否需要更高剂量的维生素 D 进行治疗。
