I would tell anyone who seems to be pron to getting cold to try this product. It is wonderful for preventing them! I usually am always sick it seems but since i have tried this product i have not been sick once! If i feel like i am getting a cold coming on i will take 6 of them that day and the symptions will usually go away within a couple day. But i take 4 everyday all the time anyway just to be sure i do not get sick.
This product is a little more expensive than i am sure most would like to pay, but it is worth it if you get sick a lot like i use to!
