My whole family and all of my friends use it. If taken at the very first signs of cold or flu it stops them immediately. We also take it as a preventive measure after/during being around sick people. It works like magic. I always have it with me in my purse. I highly recommend this product.

I've been using Boericke and Tafel Alpha CF since high school and it's always effective. Great immune booster; keeps me well throughout the year.

We feel this product really helps to keep our colds at bay. Great price at iherb. My husband likes the liquid, but my daughter and I prefer the tablets.

I bought this coz I read all the good reviews but after using it, I didn't find it very effective. Also it's quite a hassle to have to remember to take it every hour.
