Vitamin D: Study Finds Little Justification For Prescribing For Most Disease Prevention
MedicalResearch.com Interview with:
Professor Mark Bolland
Senior Research Fellow in the Department of Medicine
University of Auckland, New Zealand
MedicalResearch.com: What are the main findings of the study?
Prof. Bolland: We pooled data from randomised controlled trials of vitamin D supplements in traditional meta-analyses and trial sequential analyses to assess the effect on important health outcomes. We found that vitamin D supplements (with or without calcium) had no effect on myocardial infarction, stroke, total cancer, or total fracture, and further similar trials are unlikely to alter these conclusions. For hip fracture, the results were more complicated. There was uncertainty as to whether vitamin D by itself increased the risk of hip fracture or had no effect, whereas the combination of vitamin D with calcium had no effect on hip fracture in people living in the community, but reduced hip fracture risk in two trials of elderly women living in residential care.
