I have been taking this supplement for several years now. I was diagnosed with drug induced neuropathy in both feet in 2015 after a brain abscess. I was in severe pain. I had “shock like” piercing pain in both feet 24hrs/7days a week. I was miserable. I had tried everything. Lyrica, gabapentin….horrible drugs. I tore my left Achilles and went to a foot doctor and she sold this supplement and said her patients had great results with it. It has been a life changer for me. I am still on Tramadol but this has helped be able to function with everyday life without as much pain. Would totally recommend trying it. You will not be disappointed.
