Taking high doses of “the sunshine vitamin” doesn’t reduce the risk of broken bones in generally healthy older Americans, researchers reported
It’s the latest in a string of disappointments about a nutrient once hoped to have wide-ranging protective effects. That same study of nearly 26,000 people already had found that popping lots of vitamin D pills didn’t prevent heart disease, cancer or memory loss either.
An estimated third of Americans 60 and older take the supplements and more than 10 million blood tests for vitamin D levels are performed annually — despite years of controversy over whether the average older adult needs either.Article content “People should stop taking vitamin D supplements to prevent major diseases” — and doctors should stop the routine screenings that fuel concern, the pair concluded. They weren’t involved in the latest study.
The bigger question was whether more than that recommended amount might be better, to prevent fractures or maybe other disorders, too. To address conflicting scientific reports, Brigham and Woman’s preventive medicine chief Dr. JoAnn Manson started the largest study of its type to track a variety of health outcomes in nearly 26,000 generally healthy Americans in their 50s or older.
