Vitamin B's and overdosing

[Robert Jan]

Is it possible to take a harmful amount of vitamin B?

what would be the effect?
How much would you have to take?

For our purposes, no. It will just give you bright urine. Why do you ask?

i simply need toknow for a paper.
so any excess vitamin b will be pissed out just like vitamin c?

im not talking about "for our purposes" either im talking for any person.

excess comes out in your urine, yes. There is some speculation that regular high doses (or sustained release tablets) of niacin can cause liver damage. It's not proven and these are very large doses used for medical reasons. However, if you just go to the store and pick up some of those "b-complex" vitamins and take 5 of them, it just comes out in your urine.
