Twelve years ago I had a good friend call me and during the conversation he asked me how I was feeling. I related that I had little energy, severe joint pain and problems remembering who I even got out of bed! He told me that he knew of a product.that had helped a lot of people and sent me one weeks worth. I was shocked that in three days I started to get my energy back. In two weeks, the pain was gone and my mental clarity was returning. That was twelve years ago. I have not missed one day of taking Dr. Keller's wonderful product! And i share it with anyone who has an issue like I did!
