Results gathered after an average of 8 years show vitamin E had no effect on the incidence of prostate cancer or total cancer. Researchers also found vitamin C had no significant effect on cancer risk.
Earlier research has shown an association between vitamins E and C and a reduced risk of cancer, but those studies were not large-scale and randomized. In addition, the results of those studies werent consistent. Despite those setbacks, more than half of American adults take vitamin supplements -- and the most popular individual supplements are vitamins E and C.
