There is not enough evidence to recommend for or against taking most vitamin and mineral supplements to prevent heart disease, stroke, and cancer, a new report by the United States Preventive Services Task Force (USPSTF) concludes.

Evidence shows that there is no benefit to taking vitamin E and that beta-carotene can increase the risk for lung cancer in people already at risk, such as smokers and those with occupational exposure to asbestos, it notes.
“This is essentially the same recommendation that the task force made in 2014,” said USPSTF member John Wong, MD, professor of medicine at Tufts University School of Medicine, Boston.
