ZINC
Getting enough zinc ensures that your sex drive, potency and fertility stay in shape. Zinc’s been used experimentally to treat impotence, and it has a profound influence on the body’s ability to heal wounds and resist disease. Men tend to get only about two-thirds the RDA of 15 milligrams, particularly if we’re active. That’s because when men sweat, we lose more zinc than women. One four-ounce helping of lean beef provides almost half the daily zinc need. Other good sources are turkey, seafood , cereals and beans. Too much zinc can hinder the work of other minerals, so experts recommend taking no more than one 15-milligram supplement a day.
