I was starting to experience tingling in my fingertips. Not bad enough to see a doctor, because I could just shake it out, but disturbing to me. I saw your ad for Advanced Nerve Support and gave it a try. Things seemed to improve, and I wondered whether the condition just cleared up on its own. So I stopped using Advanced Nerve Support for a while and the tingling came back, not as prominently as before, but there it was. So I started the supplement again, and saw improvement again. I think it really works, and I will be buying it again!
