Vitamin D Supplements Don’t Work: Study

Vitamin D supplements don’t improve bone health, major study finds

London, CNN – Vitamin D supplements do not improve bone mineral density or prevent fractures or falls in adults, finds a large study that advises health professionals to stop recommending the supplements to most patients.

The vitamin has long been associated with a decreased risk of a number of conditions, such as osteoporosis and hypertension, in addition to keeping bones strong by helping the body absorb calcium — which is why many use it during the dark winter months.

But the study’s authors say there is “little justification” in doing so when it comes to bone health.

“Our meta-analysis finds that vitamin D does not prevent fractures, falls or improve bone mineral density, whether at high or low dose,” lead author Dr. Mark J. Bolland, associate professor at the University of Auckland in New Zealand, said in a statement.

The research, published in the Lancet Diabetes & Endocrinology, analyzed data from 81 randomized controlled trials — involving more than 53,000 people — that studied whether the over-the-counter supplement helped in fractures, falls and bone density.

Most studies included women over the age of 65.

The team concluded that vitamin D does not prevent fractures or falls, or have a meaningful effect on bone mineral density, concluding that there is little justification in taking them to “maintain or improve musculoskeletal health,” adding that there is no need for more trials to explore this.

But the research also concludes the supplement is helpful in preventing rare conditions such as rickets and osteomalacia in high-risk groups, which can occur after a prolonged lack of exposure to sunshine, resulting in deficiency.

Not a cure-all

Bolland suggests doctors and health officials currently recommending the vitamin to older patients as a way to prevent osteoporosis or brittle bones should stop. “Clinical guidelines should be changed to reflect these findings,” he said. READ MORE AT CNN.
