What Are Signs of Zinc Deficiencies?
The first sign of zinc deficiency is the loss of taste and smell. More severe deficiencies can lead to stunted growth, small sex glands in boys, impotence, and delayed wound healing. Severe deficiencies are uncommon in the United States, but mild ones aren’t. Zinc is one of four nutrients most often deficient in the diet of toddlers (the others are folate, calcium and iron). Zinc is relatively non-toxic except when consumed in large amounts, like overusing zinc supplements.
