I wouldn’t be without it. In the 5 or 6 years that I have been taking this product, I have never had a cold or flu. I was diagnosed with hemochromatosis some years ago, and had to have phlbotomies about 12 or more times a year to keep my iron count down. I have not had a phlobotomie now for about 2 years Go figure. I have never even noticed any taste in it, mix it with yogurt — it’ great!
