Kosher supervision on vitamins
We are confused about the kosher supervision of vitamins, since we are israelis living in Florida, USA. We do not know the halachah over here, and we wanted to know if vitamins need kosher supervision. I bought vitamin D that has the American seal of O. U. D (D meaning dairy), which, when it comes to food, I don't eat. My question is: when it comes to vitamins or medicins, is there a difference?
It's okay to take them.
