Hello - I am a new member here. My local neurologist has prescribed me Metanx (and Ive viewed the sticky on supplements). However, I saw a neurologist that specialized in pain who wants no b6 supplementation at all saying it can cause pain. My b6 level was at the low end of the range at 40. What I have been able to research is that very high levels of b6 can cause neuropathy but these were considered toxic doses. My doctor prescribing Metanx has given me a script to have b6 and b12 levels draw n a month after taking it. I'd appreciate any thoughts that might help me make a decision in light of these divergent opinions. BTW I have SFPN from autoimmune disease and am being treated with Trileptal, but it wears off by 3-4 pm. I am also having IvIg done monthly staggered with bolus steroids. Thanks!
