vitamin B if taken regularly can cause nerve damage

I was googling for Berocca vitamins info on the web, and I found this on the wikipedia
“vitamin B if taken regularly can cause nerve damage”
I was happy, as Berroca is cheaper than Natural Life or Qualivitz vitamins,
and it has more B complex.
But now……??
