關於VC和Common cold,Mayo Clinic確實這麽說:

來源: 2022-12-25 20:19:19 [舊帖] [給我悄悄話] 本文已被閱讀:

Common cold. Taking oral vitamin C supplements won't prevent the common cold. Evidence also shows that the benefits of regularly taking vitamin C supplements to reduce the duration or severity of a cold are minimal.

 

普通感冒。口服維生素 C 補充劑不能預防普通感冒。證據還顯示,定期服用維生素 C 補充劑以縮短感冒持續時間或減輕嚴重程度的益處極小。

 

如果很多人補充VC,包括大劑量一般水溶性VC、Ester-C、Liposomal Vitamin C,是為了增強抵抗力,和流感、新冠之類的病毒抗爭,但上述敘述似乎又是不鼓勵的暗示。
