London: A new study has revealed that healthy adults do not need to take vitamin D supplements, as it does not improve bone mineral density, which is an indicator for the risk of osteoporosis.
Researchers at University of Auckland analysed 23 studies involving more than 4,000 healthy people and found that the supplements fail to increase the density of bone mineral in the body as a whole, the BBC reported.
The study's lead author, Prof Ian Reid, said that the findings suggested that the targeting of low-dose vitamin D supplements only to individuals who are likely to be deficient could free up substantial resources that could be better used elsewhere in healthcare.
Meanwhile, Clifford J Rosen from the Maine Medical Research Institute agreed that science's understanding of vitamin D supports the findings for healthy adults, but not for everyone.
Rosen said that supplementation to prevent osteoporosis in healthy adults is not warranted.
However, maintenance of vitamin D stores in the elderly combined with sufficient dietary calcium intake remains an effective approach for prevention of hip fractures.
The study is published in the Lancet.
