I am also interested in any good scientific references to findings that vitamin B6 "causes neuropathy"[/color][/b]
Quoting from NIH (National Institutes of Health Office of Dietary Supplements:
Can vitamin B6 be harmful?
People almost never get too much vitamin B6 from food or beverages. However, taking high amounts of vitamin B6 from supplements for a year or longer can cause
severe nerve damage, leading people to lose control of their bodily movements. The symptoms usually stop when they stop taking the supplements. Other symptoms
of too much vitamin B6 include painful, unsightly skin patches, extreme sensitivity to sunlight, nausea, and heartburn.
That sounds like I very well might have screwed up with B6. So here's hoping they are right that it usually goes away once stopped. I hope the neuropathy is not permanent.
