含易誤解內容！英國針對5項研究的回顧審查已表示：「沒有證據表明缺乏維生素D，是COVID-19的獨立危險因素」，強調「研究中發現有關聯性，並不代表具備因果關係」。
1. 老年人、肥胖者均較容易存在維生素D缺乏症，而這些人群本身即為較高風險者，相關研究也忽略種族及社會經濟地位所導致的醫療弱勢狀況，若針對此類潛在混雜因素調整研究分析，則可發現COVID-19與維生素D水平之間缺乏獨立關聯。
2. 雖然確實有研究認為，維生素D水平較高的國家，covid-19的病例數和人均死亡率較低，但此類調查攸關各國家實施的檢測次數與防疫政策，並無法證明死亡率與維生素D具備因果關係。
3. 雖然維生素D確實對健康至關重要，但目前醫學界共識性文件並不鼓勵廣泛食用維生素D營養品，也沒有科學證據證明攝入維生素D能預防或治療COVID-19。
