This supplement has given me a life without back pain from a dislocated vertebra that's been there for many years. The orthopedist told me, the only way to fix it was a rod in my back. I said, I'll find another way. I already used another supplement from Advanced Bionutritionals, so I thought I would try the nerve supplement, as well. In three days I felt results and after two months I am pain free all day and most of the night. I take a half pill with each of my three meals each day. This is an answer to prayer!
