2024年8月12日 · 維生素D對鈣元素在人體內的平衡和代謝中具有重要作用，可用以預防 佝僂病 和「成人骨軟化症」，與鈣質合用可以預防出現常見於老年人群的 骨質疏鬆症。 此外，維生素D對於神經肌肉功能、 炎症 都有功效，同時還影響許多基因的表達和轉譯，調節細胞的增殖、 分化 和 凋亡 [3]。 維生素D的主要天然來源是通過 日光照射 後在皮膚表皮的下層的化學反應生成膽鈣化固醇（特別是 UVB輻射） [4][5]，而 維生素D 3 需由 紫外線 照射後，由7-去氫膽固醇經光照進行光化學反應轉變而成，動物皮膚細胞中含有7-去氫膽固醇，因此多曬太陽是獲取維生素D的簡易方法。 人類一天只需暴露在陽光下10分鐘，自身即可合成足夠的維生素D 3[6]。
