I'm new here to and when I was first suspected I had Neuropathy I did a lot of on line research. The lack of B Vitamins was one thing that kept coming up so I started taking B 6 and 12 supplements. When I finally did see a doc, and blood tests were done on me, the results showed an excess of Vitamin B and the doc told me not to take any supplements. although my Vitamin D was very low and pharmacy amounts were prescribed. Has anyone else had a proble with having too much Vit. B?
