1)Vitamin A in large doses is toxic, a fact known for a very very long time. As a matter of fact excess in anything is harmful.
2) Calcium can not be used by the bones unless there is vitamin D, that is the problem in Sweden where there is not as much sun as in other places for the body to make vitamin D.
3)They spent 17 mns of a 45 mns documentary telling us that vitamin C can not prevent you from catching a cold but it can help you get rid of it once you have it. Big deal !!
Anyway, this episode is not very good.
