Taking vitamin D could cut the danger of heart attacks and other cardiovascular problems for the over 60s, according to researchers in Australia. Their findings, from a clinical trial, have been published in the British Medical Journal. They stress that the absolute risk difference is small but say this was the largest trial to date and further evaluation is warranted, particularly on people taking statins and other cardiovascular drugs. Observational studies have consistently shown a link between the supplement and the risk of cardiovascular disease, but previous randomised controlled trials have failed to produce the evidence.
