Exercise increases zinc loss from the human body, and zinc deficiency can compromise muscle function. Athletes who do not eat an optimal diet, especially those who are trying to control their weight or use fad diets while exercising strenuously, may become deficient in zinc to the extent that performance or health is compromised.
People who may benefit from a zinc supplement include those who do not consume enough calories: athletes, vegetarians, and the elderly. Anyone with a low caloric intake is at higher risk for having a low zinc. Therefore, it is important for individuals in these groups to include sources of zinc, including zinc supplements, in their daily diet.
