@dcgirl, B12 is just one of the supplement I take for my small fiber peripheral neuropathy. I've been taking it since 2016 and I feel like it has helped me by slowing and possibly stopping the progression of my neuropathy. I still have numbness in my feet but it's not as bad as it was when I started taking the supplements listed in the discussion below. I don't believe there is any one single vitamin you can take to help with the pain or numbness of neuropathy.

Protocol 525 product for neuropathy relief?
