I've been using Silver Biotics personally for a long time. It has done everything I've needed, from healing sores to bronchitis to a tooth root Abscess. Recently my 33-year-old horse was diagnosed with a liver bile duct infection. He was on two antibiotics (including Baytril, very strong) and very slowly the two high liver values were coming down. But he wasn't eating his mashes (at 33 his teeth can't properly masticate hay) and losing some weight. Last Wednesday, after reading a couple of articles online about silver's antibiotic-boosting properties, I gave Fred two ounces of Silver Biotics. On Thursday his blood was drawn. On Friday the results came back. The two high liver values had dropped from the 800-range to the 500 range. The first time that big a drop has happened. Additionally, he seems to have regained his appetite and is eating his mashes again. I've been a fan of this product for a long time, but am a much bigger fan now. I emailed his vet and said if I didn't hear otherwise from her, I was going to give him an ounce of Silver Biotics a day (also sending her text from one of the articles mentioned above). I haven't heard back so will continue to do this. Do yourselves a favor and give this product a try. You won't be disappointed
