Anyone have any idea of the amount that may cause toxicity? My wife has lost 15 pounds eating well, exercising and taking Speed V2. I finally talked her into a multivitamin, but I just want to make sure she will be ok.
1667% in the opti-women and 4,167 in the Speed V2.
Myself and others have taken in more than this, but not sure how this affects a women.

I wouldn't worry about it too much unless it was an extremely high amount, which I doubt it is. The B vitamins are water soluble so any excess will just get peed out. Yellow pee!

B-12 is the one B vitamin that the body keeps a long term reserve of.I wouldn't worry about it too much unless it was an extremely high amount, which I doubt it is. The B vitamins are water soluble so any excess will just get peed out. Yellow pee!
But I still agree with you. B-12 toxicity isn't really that common, it doesn't even have an established UL and typically has a very poor absorption rate anyways.
