The mineral iron is essential to good health; the body needs it to transport oxygen and regulate cell growth. Since iron is abundant in a variety of common foods, men generally do not need to take additional iron unless they suffer from renal failure or have a disorder that prevents iron absorption. Further, according to the National Institutes of Health Office of Dietary Supplements, some research suggests a link between high iron levels in the blood and an increased risk of cardiovascular disease. If you want to take a multivitamin and mineral supplement, you may want to choose one that does not contain iron.
