食物中的維生素D可分為兩種,存在菇類或酵母中的維生素,稱之為麥角固醇,存在動物性食物中的稱之為7-去氫膽固醇,經過日光照射後,前者轉變成維生素D2,後者則轉變成為生物D3。一般含維生素D較多的有魚肝油、肝臟、蛋黃和牛奶,人體食入後,會移到皮膚,經日光照射後產生維生素D3。
美國早在1930年就在牛奶中添加維生素D3,而市面上所賣的鈣片,也大半添加維生素D3。維生素D有幫助鈣質吸收,因此有強健骨骼的作用,牛奶中本身就富含鈣質,因此添加維生素D3,有加成吸收鈣質的作用。含有維他命D3的食物:魚類缺乏症:佝僂病攝取過量之症狀:高血壓,心律不整,噁心,體重減,抽搐,腹痛,食慾不振,精神和身體成長受阻,動脈提早硬化以及腎臟損壞.
