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.
Vitamin D supplements don't improve bone health, major study finds
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 findings add to previous research suggesting that vitamin D supplements do not prevent disease for the majority.
