As for B12 you really can’t consume too much of it. You body produces something called intrinsic factor that is essential to the absorption of B12, so you can only absorb so much; that is why many elderly have B12 deficiencies, not from intake but from the reduced intrinsic factor.

I truly don’t know about the B6 and what the tolerable upper limit of intake is for it. If no one else responds with an answer to it, PM me and I will look it up in one of my text books. Hope I helped.
