I THOUGHT I'd been doing all the right things taking extra calcium, magnesium, Vit D, a co-enzyme B complex and a good brand of multi-vites. I kept getting NUMB-ER. So, I sat down and took a good look at all my supplements' labels. I found out that B-6 was in the multi-vites well in excess of basic daily requirements, The B-complex also, plus the calcium caps included extra '6' to the point where I was getting between 8-10 times what should be considered normal. So I stopped all supplements, got on the net and found what I needed in combinations that did not have the B-6 bonus. For a multi-vite I chose a pre-natal type, it's got the lowest B-6 levels in it and that allows some wiggle room. Since I've gotten all these sorted out, I'm doing a lot better.
That is my experience, I believe if you go to the 'search' part of the top blue bar and type in 'B-6' you could easily find prior posts on the issue here, and also on other parts of Neurotalk....you are not alone with this problem. - j
