Vitamin D supplements fail to show bone benefit in elderly

In another blow for vitamin D supplementation in healthy adults, findings from the largest population-based trial to date have found no bone mineral density advantage compared with taking a placebo.
Researchers from the VITAL trial, of almost 26,000 adults unselected for vitamin D insufficiency, have reported on a subgroup of 771 participants who had not been on any bisphosphonates or other bone active agents for two years prior to enrolment.
