[Expired]Emergen-C 1000mg Vitamin C Powder

: One pack a day is enough, and it's not advisable to drink it every day. I usually have it when people around me catch a cold or when my throat feels itchy. Excessive intake of vitamin C isn't good either. 1天1包就够啦，也不能天天喝，我一般是周围有感冒的时候喝 自己嗓子痒痒的时候喝，VC摄入过量也不太好的

回复 @温野菜菜子wwy : Yeah, exactly. Drink it to prevent colds or when you have very mild cold symptoms. If you already have obvious cold symptoms, it'll be too late. 嗯嗯 就是这样，提前预防感冒或者有轻微微感冒症状的时候喝，已经有明显感冒症状的时候就来不及了
