Why do vitamins make your pee bright green?

Question

I take potassium, B Complex and Calcium and for the whole day my urine looks radioactive, which one is causing this why?

Answer 1

It means the vitamins arent soluable, and you arent absorbing them. They're either not very good vitamins or you're already getting enough and your body is getting rid of the excess.  Try better vitamins.

Answer 2
