I recently purchased a variety of the Kyolic garlic products. I had been taking the original formula on and off but then we went on vacation and I got a horrible sinus infection from a mold allergy. When we got home, I tried all the usual natural remedies for sinus infections (oregano oil, colloidial silver, steam inhalers, grapefruit seed extract), but none of them helped. Last night, I finally looked through my stash of Kyolic Garlic and picked up Kyolic Reserve. After taking one tablet, my head started to clear. I even heard my ear pop as I was sleeping and have continued to feel better after taking a few more doses. I am just elated that I found such a powerful natural antibiotic and that I am feeling better. I cannot recommend this version highly enough and I will continue to take it on a daily basis. It has cleared my sinus infection and I am so grateful I won't need to head to the doctor. I felt compelled to write this review based on my experience even though I bought the product 3 months ago
