I heard about this last night on coat to coast and they had the heart doctor on and he said they were giving these folks 10,000 iu a day or 140,000 iu’s a week. That would be fine is the person was sub normal not getting any daylight vit D but in the long run it was to much. He recommended around 3,000 to 4,000 iu a day.Thanks.
10,000IU daily is far more than most people would consider taking.
Now I'll go bang my head for taking health advice from Coast to Coast. ;-)
