Researchers at the University of Toronto conducted a meta-analysis of all published randomised controlled trials that looked at the effects of vitamin supplements on the risk of heart disease and stroke. They found that the most commonly used supplements provided no benefit to prevent such health problems. Instead, the researchers proposed that the best way to look after the heart was by getting vitamins and minerals not from supplements, but from a healthy diet. Professor Clare Collins, Director of Research for the School of Health Sciences at Newcastle University joined the Daily to discuss this further.
