摘要：
维生素D是调节和帮助可持续健康的最重要的生物分子之一，然而,根据研究，缺乏这种多功能维生素是常见的。维生素D,除了以维生素的形式发挥作用，也作为多功能激素（类固醇）。维生素D在体内通过各种步骤从紫外线辐射开始合成，来自有限的食物来源，然而,维生素D强化食品仍然是维生素D的主要来源之一。重点关注维生素D如何在正常或特定条件下通过影响体内的不同功能而发挥多功能分子的作用，以及维生素D在强化中的重要性以及迄今为止如何从现有文献中对其进行管理。在Covid大流行期间,人们意识到维生素D并服用补充剂，强化食品,坐在阳光下。随着COVID患病率的下降，人们开始忘记维生素D。维生素D对整体健康至关重要，因为它可以减少炎症，对各种疾病具有保护作用，癌细胞的生长，并有助于控制感染，增加新陈代谢，肌肉，和骨骼强度，神经递质表达，等。因此,这次审查是为了激怒民众，必须确认每日维生素D推荐的膳食摄入量的实现。
