Harvard Study: Vitamin C and E Supplements Safe

A study from Harvard researchers, the Physicians’ Health Study II (PHS II), concluded that long-term vitamin C and E supplement use does not increase the risk of prostate cancer or other cancers. They also discovered that vitamin C supplements were possibly associated with a 46% reduction in colorectal cancer during the study's follow-up period. Published in the American Journal of Clinical Nutrition, the results are important because they contradict previous findings from 2011 that found vitamin E could increase prostate cancer risk. The PHS II is currently the only large-scale, randomized, double-blind, placebo-controlled trial looking at the effects of long-term use of vitamin C and E supplements on chronic disease.
