In order to repair micro tears that can occur as a result of strenuous exercise, serious athletes usually require higher amounts of most vitamins and minerals--including zinc--than sedentary people.

Zinc is essential to keeping the immune system strong. For athletes, this is especially important, since being sidelined with a viral infection, or other illness, can force one to miss valuable workout time.

Zinc deficiency is problematic as plasma testosterone is regulated in part by zinc. Therefore, a zinc deficiency may adversely affect this hormone, causing muscular mass and strength to suffer. Your doctor can administer a routine test to determine whether or not you are deficient in zinc.
