This is effective
I like Emergen-C a lot. I notice that it does support my immunity. I would take this as a regular supplement when I was really active in sports. Also, if you drink alcohol, this helps curb hangovers if you take it before and after drinking alcohol. I notice I prefer taking this after getting some food in my stomach, otherwise I feel woozy for about 15 mins. The taste is alright. Not terrible.
