I have taken it for glucose control. It seemed to work for that very well but I found it upset my stomach too much. It's purported to be a healthy alternative to metformin. I didn't find it was something that provided pain relief. I found benfotiamine and R-Lipoic Acid were just as effective , gave some pain relief and didnt upset my stomach.

The one I used was called Good State Glyco-X 500.
