“No proof” vitamin D stops colds 維他命D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.

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

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

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.”

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。一百六十一名每天吃維他命D連吃十八個月的人,與吃安慰劑的一百六十一人感冒機率相同。

這項研究發表在《美國醫學協會期刊》。

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。

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。」
