Exceeding 4,000 IUs Of Vitamin D May Lead To Health Problems.

“To Your Health” blog reports that a viewpoint published online Feb. 19 in the Journal of the American Medical Association observes that “some physicians are prescribing large doses of Vitamin D supplements for their patients in the hope of preventing cancer, cardiovascular disease, diabetes, autoimmune disorders and other maladies, despite a lack of evidence that this works.” In some cases, people are taking big daily doses of vitamin D all on their own. But, if people exceed “4,000 IUs, unless there’s a specific reason” such an amount is needed, they “risk kidney stones, calcification of blood vessels and possibly the very cardiovascular disease” they are trying to stave off, one of the viewpoint’s authors “said in an interview.” http://www.washingtonpost.com/news/to-your-health/wp/2015/02/24/lay-off-the-mega-doses-of-vitamin-d/
