Vitamin D supplements do not improve bone health

However, a series of studies showed that vitamin D produced in the form of supplements, prevents fractures and improves the mineral density of bone tissue. "The report included all available trials of vitamin D, but such trials included too few participants, used an insufficient dose of vitamin D, and had an insufficient duration of treatment", said Dr Robert Clarke, professor of epidemiology and public health at the University of Oxford.

Two of the study's three authors - Mark Bolland and Andrew Grey, both from the University of Auckland - have been leading investigations into vitamin D since 2012, and each time they have presented dubious conclusions about the benefits of the supplement. In a review of previous trials, they found that supplements do not improve bone health nor prevent fractures and falls.

Prof Bolland said things have changed since 2014, when the last major review of the evidence was carried out.

Vitamin D supplements have traditionally been recommended for older people to treat or prevent osteoporosis, after early evidence suggested benefits for bone health. In the last four years, "more than 30 randomised controlled trials on vitamin D and bone health have been published, almost doubling the evidence base available", he added. Everyone else, up to the age of 70, are recommended to take 600 IU of vitamin D to maintain bone health and calcium metabolism.

He added that further trials looking at the effects of vitamin D on bone health would be pointless.

The best way to naturally get the flawless amount of vitamin D needed by the body to stay healthy through exposure to the sunlight.

A new meta-analysis by medical researchers in New Zealand and Scotland has seriously called into question whether vitamin D supplementation has any effect on bone health.

The research examined data from 81 trials which involved more than 53,000 people to study whether vitamin D supplement helped in fractures, falls or bone density.

They were also very clear, Prof Avenell said, that people who were never exposed to the sun because they covered themselves up or were institutionalised were at risk of vitamin D deficiency.

"I look forward to those studies giving us the last word on vitamin D", Professor Gallagher concluded. However artificial intake of the supplements, based on the same vitamins are statistically proven to be useless.
