Zinc is an essential mineral that helps with wound repairs, protein synthesis, cell reproduction, immunity, vision, and supports fertility in adults and growth in children. It also alleviates glycated hemoglobin, insulin resistance, Type 2 Diabetes, and cardiovascular disease.
Human body uses zinc to fights off infections and produce cells. In addition, zinc plays a key role in healing injuries and creating DNA. Although zinc is a valuable mineral during illnesses, there are many other ways that it becomes depleted. These include: vigorous exercise, alcohol consumptions, pregnancy, and taking oral contraceptives.
Many people think that copper and zinc should be supplemented together. However, there are some reasons why most zinc supplements do not contain any copper. 1) Zinc deficiency is more common than copper deficiency, but copper overload is very common. 2) Copper toxicity is very common and problematic because it cases DNA damage and cases oxidative stress. Therefore, zinc is used to prevent the symptoms of copper toxicity in early stages because zinc competes with copper for absorptions in the GI tract.
