Zinc is present in all body tissues and fluids, and forms an essential part of a large quantity of enzymes participating in the metabolism of carbohydrates, fats, proteins and lipids. The presence of zinc in enzyme molecules is primarily required for the actual catalytic function of the enzyme, but zinc also participates in fixing the spatial structures. The main sources of zinc in nature are mostly whole grains, nuts, some legumes, asparagus and eggs.

Zinc contributes to normal acid-base metabolism, normal carbohydrate metabolism, normal cognitive function and normal DNA synthesis. Further, it contributes to normal fertility and reproduction, normal macronutrient metabolism, normal metabolism of fatty acids and normal metabolism of vitamin A. It also contributes to normal protein synthesis, the maintenance of normal bones, normal hair, normal nails and skin. Zinc contributes to the maintenance of normal testosterone levels in the blood, the maintenance of normal vision, the normal function of the immune system, the protection of cells from oxidative stress and has a role in the process of cell division.
