Excessive use of multivitamins/multiminerals (“multis”) has been associated with an increased risk of prostate cancer. This warning is based on a large study in which researchers evaluated 395,344 men who were cancer-free when they enrolled in 1995 and 1996. Over the next five years, 10,241 men were diagnosed with prostate cancer: 8,765 men had localized disease and 1,476 had advanced prostate cancer. A separate analysis was done over six years to evaluate mortality, and 179 men were found to have fatal prostate cancer in this arm of the study. (Lawson 2007)
Overall, when the researchers compared the men who did not use multis excessively, there was no increased risk of localized prostate cancer. When men who used multis more than seven times a week were compared with those who never used the supplements, the investigators saw an increased risk of both advanced and fatal prostate cancers. The increased risk was greatest among men who took individual micronutrient supplements, including carotene, selenium, and zinc, as well as high levels of multivitamins.
