目前尚不清楚補充維生素D是否能降低癌症或心血管疾病的風險，隨機試驗的數

目前尚不清楚補充維生素D是否能降低癌症或心血管疾病的風險，隨機試驗的數據也有限。即便實驗室研究顯示，低量的25-羥基維他命D與癌症和心血管疾病發生率上升有關，但因太多偽保護因子，而無法建立確切的因果關係。

It is not clear whether vitamin D can reduce the risk of cancer or cardiovascular disease, data from randomized trials is limited. Even laboratory studies have shown that low levels of 25-hydroxy vitamin D to cancer and cardiovascular disease incidence increased about, but too many pseudo-protection factor, but can not establish a definite causal relationship.
