It works!

Every time I start to feel the onset of a cold I take two of these vitamins and every few hours, depending on how I feel, I take two more but most of the time the first two will really make a difference. I work with children and have battled the onset of many colds thanks to these vitamins.

Wanted them to work

I really wanted these to work. I have tried them on two separate occasions when I started to get sick. Unfortunately for me I don’t think they made much of a difference.

Keep these on hand at all times

I am convinced these have at times either completed prevented or stopped the onset of colds/sore throats for me. I wasn’t much of a believer, but a friend convinced me to try these. Never. Turning. Back!!! I always have them in my bag in case I start to feel any bit of a cold coming on or if someone around me is sick.

What a godsend!

I have a compromised immune system and have been unable to travel abroad without returning sick. I tried QD for the first time last spring during the last leg of a UK trip. Not even a sniffle! I've continued to take it any time I'm around a lot of people, ie. a casino. I haven't been sick once this season. Very unusual for me. So happy I discovered this product!
