Vitamin D is a fat-soluble vitamin which has the regulation of calcium-phosphorus metabolism in the body as its main function. Vitamin D receptor is present in most of the nucleated cells of the body, and its role in multiple body processes is being discovered. The 3 main sources of vitamin D are ultraviolet sun radiation, diet, and supplementation. The skin, through solar radiation, provides 90% of the bodýs vitamin D needs. In cases of low vitamin D, sun exposure habits and diet must be reviewed, and pharmacological supplementation must be assessed. Measurement in the body is performed by determining 25-hydroxycholecalciferol with values below 20ng/ml being considered insufficient. Universal screening of vitamin D is not currently recommended, only in situations where a deficiency is suspected.
维生素D是一种脂溶性维生素，其主要功能是调节体内钙磷代谢。维生素D受体存在于人体大多数有核细胞中，其在多种身体过程中的作用正在被发现。维生素D的3个主要来源是紫外线太阳辐射、饮食和补充剂。皮肤通过太阳辐射提供人体90%的维生素D需求。在维生素D水平低的情况下，必须检查日晒习惯和饮食，并评估药物补充情况。通过测定25-羟基胆钙化醇来进行体内测量，值低于20ng/ml被认为不足。目前不建议对维生素D进行普遍筛查，仅在怀疑缺乏的情况下进行。
