Healthy adults do not benefit from taking Vitamin D supplements after a report suggested they had no effect on bone density.
The elderly are advised to take vitamin D
A study published in The Lancet suggests that bone density, a common sign of osteoporosis, was not improved by taking vitamin D supplements.
Health experts believe that people should not stop taking supplements as other factors could be involved in the results.
A team of researchers from New Zealand conducted random trials on health adults for roughly two years to analyse the bone density and effects of vitamin D supplements.
Trials took place in different countries including the UK, where the government recommend children and over-65s should take a daily supplement.
Bone density measures the strength of bone and the presence of bone minerals at different sites around the body. Poor bone density can be seen as a precursor to osteoporosis which can increase the chance of a bone fracture.
The results identified no conclusive evidence that people who took vitamin D had significant health benefits. The results did highlight that small but significant increase in bone density was discovered between the top of the femur near the hip joint.
This finding is not believed to be of huge significance clinically, according to the study authors.
Professor Ian Reid from the University of Auckland led the study and believes healthy adults do not need to take any vitamin D supplements.
Prof Reid said: “Our data suggest 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."
Health experts are not surprised by the findings and Dr Laura Tripkovic from the University of Surrey believes other factors play a huge part in bone density.
Dr Tripkovic said: "I'm not surprised they didn't find any evidence of the effects of vitamin D on bone density because there are so many other factors involved in osteoporosis, like genes, diet and environment.”
Health insurance can be tailored to suit your family and usually family policies are more cost-effective than individual ones.
