More Vitamin D Doesn’t Always Mean Stronger Bones
High doses of vitamin D do not appear to protect postmenopausal women from the dangers of osteoporosis, new research indicates.
“While high-dose vitamin D did indeed increase calcium absorption, the increase was only 1 percent and [it] did not translate into gains in spine, hip or total body bone mineral density,” said study author Dr. Karen Hansen.
In fact, Hansen, an associate professor of medicine at the University of Wisconsin School of Medicine and Public Health in Madison, noted that she and her colleagues “did not find any benefit of vitamin D, in either high or low dose, on muscle mass, two tests of muscle fitness or fall [risk].”
The team reported the results online Aug. 3 in the journal JAMA Internal Medicine.
