It takes a LOT of effort. Like in excess of 50K UI a day for months. And then it needs co-factors to do harm, like excess calcium intake along with a K2-MK7 deficiency and/or a potassium deficiency (both of which are, unfortunately, very common). All in all, it's a very complex system that interacts with the body's buffering mechanisms.
