A new report has highlighted evidence to support the health benefits of vitamin D supplements.
The report, which will form the basis of a National Institutes of Health conference in September, will examine a range of evidence that suggests vitamin D supplements can improve the bone health of postmenopausal women and older men.
Authors found that vitamin D3 taken with calcium helped to decrease the rate of falls, fractures and bone loss among elderly people.
They also noted that taking vitamin D in excess of the current recommended levels does not appear to have adverse side-effects, although they noted that the majority of trials using higher doses of the vitamin were not adequately designed to assess potential harm.
Dr Carolyn Clancy, director of the Agency for Healthcare Research and Quality, commented: "The vitamin D and bone health evidence report provides valuable insights because it is based on an independent and rigorous examination of the totality of evidence across all age groups and during pregnancy and lactation."
The expert added that such a review is important for enabling health care decisions to be made.
