Conversely, a few years ago I started taking a multivitamin with B12.

Some months later began to experience a weird tingling in my right big

toe. Saw a specialist. He suggested the problem could be excessive

vitamin B12 and ordered a blood test, which confirmed his hypothesis.

Quit taking the supplement and the tingling quickly disappeared.

High doses of B6 can cause neuropathy, but I haven't heard of high B12
intake causing it. Multivitamins usually contain B6.

Yeah, after responding I started wondering if it was B6 rather
than B12. Pretty sure, now, it was B6.



The Linus Pauling Institute has good (and I think trustworthy) information on vitamins:
