It's not exotic, but it is a must for everyone who doesn't get enough fruits and vegetables. (That's you, and up to 80% of other men.) Rather than megadoses of nutrients, look for one pill that provides 100% of your daily requirements for as many different vitamins and minerals as possible. (Amounts exceeding 100% are generally a waste.) And make sure you buy a men's formula, without extra iron. Excess levels of the mineral could increase your risk of heart disease (a condition called hemachromatosis), says Doug Kalman, M.S., R.D., director of clinical research at Miami Research Associates.
