"No proof" vitamin D stops colds 維他命擋感冒「沒有證據」

Scientists say they can find no convincing evidence to show that taking vitamin D supplements will fend off a cold. The 161 people who took daily vitamin D for 18 months caught as many colds as the 161 who took fake pills.

科學家說,他們未能發現具說服力的證據,顯示吃維他命補充品可對抗感冒。161名每天吃維他命D連吃18個月的人,與吃安慰劑的161人感冒機率相同。

The study was reported in the Journal of the American Medical Association.

這項研究發表在「美國醫學協會期刊」。

But a leading UK cold expert said vitamin D was useful. Prof Ronald Eccles, of the Common Cold Centre at Cardiff University, said it can give the immune system a much-needed boost during winter when vitamin D reserves may be low.

但英國知名感冒專家說,維他命D很有用。卡地夫大學感冒中心主任愛爾柯斯教授說,維他命D能在冬季給予免疫系統非常需要的幫助。

He said echinacea supplements may also help ward off coughs and colds, but added: "Supplements do not work for everybody because people’s immune systems are different. It’s not a case of one size fits all."

他說,紫錐菊補充劑或許也能對抗咳嗽與感冒,但「補充劑不是對每個人都有效,因為免疫系統因人而異,並非一體適用。」
