Is 41667% of B12 dangerous or unhealthy? ? ? ? ? ? ? ?

Question

I bought these little drinks at costco, and on the back it says like 100% vitamin C, then for b12 it says 41667% !!! is that unhealthy or dangerous?

Answer 1

You're safe. There are no tolerable upper level intake requirements for Vitamin B12; however, you can overdose on some other vitamins.

Answer 2

B vitamins are water soluable. Which means, the more you drink, the more you lose. So you'll very likely just flush it out. However, anything you buy in a bulk or cheap food place, like CostCo and WalMart is going to be using cheap ingredients. Which isn't good.
