In it, 18,000 people who were at an increased risk of lung cancer because of asbestos exposure or smoking received a combination of vitamin A and beta-carotene, or a placebo. Investigators stopped the study when they found that the risk of death from lung cancer for those who took the vitamins was 46 percent higher. Then, in 2004, a review of 14 randomized trials for the Cochrane Database found that the supplemental vitamins A, C, E and beta-carotene, and a mineral, selenium, taken to prevent intestinal cancers, actually increased mortality. Another review, published in 2005 in the Annals of Internal Medicine, found that in 19 trials of nearly 136,000 people, supplemental vitamin E increased mortality. Also that year, a study of people with vascular disease or diabetes found that vitamin E increased the risk of heart failure. And in 2011, a study published in the Journal of the American Medical Association tied vitamin E supplements to an increased risk of prostate cancer. Finally, last year, a Cochrane review found that “beta-carotene and vitamin E seem to increase mortality, and so may higher doses of vitamin A.” When you put it that way, vitamins look bad.
