10 Benefits of Zinc for Men

Boosts Sexual Health and Testosterone Levels

Called "the ultimate sex mineral" by Men's Health magazine, zinc influences a man's fertility, potency, sex drive and long-term sexual health [source: Roman]. Zinc is essential to sperm production, and most men can blame decreased semen volume and testosterone levels on low zinc supplies. In fact, each ejaculation can expend up to 5 milligrams of zinc, or almost half of a man's daily allowance. So if you're getting ready to start a family, a little extra zinc could help boost your fertility.

Scientists at Wayne State University School of Medicine in Michigan investigated the effects of zinc on testosterone levels in men between 20 and 80 years old. The study revealed that young men who restricted dietary zinc intake for 20 weeks experienced decreases in testosterone, while zinc-deficient elderly men taking zinc supplements for six months experienced increases in testosterone production.

The good news is that it's easy to keep your body's zinc stores in check. Four ounces (113 grams) of lean beef provide half the daily recommendation; oysters are another good source. Zinc is also abundant in turkey, cereals and beans [source: Roman].
