My husband has been using this product for a while and although I could get it elsewhere, Amazon had a better price. The reason for the negative review is, my husband feels that the product got frozen during the shipment time, the capsules are leaking and sticky. They leave a awful taste in your mouth and they don't seem to be working as well as they have in the past. Would actually like to see about a replacement as this is not a cheap product to take. Couldn't find where I could contact anyone for help with a replacement. A good product, if it is stored and handled correctly, this past shipment wasn't handled correctly.
