Zinc Overview:

Zinc is a metal/element that helps wound healing. It provides protection against cell death. According to WebMD, “Zinc is used for treatment and prevention of zinc deficiency and its consequences, including stunted growth and acute diarrhea in children, and slow wound healing”. Zinc topical ointments can be used for psoriasis, eczema, and acne. Also it can help improve infections and increasing wound healing.

There are also many other uses for Zinc. Zinc supplements are used for problems with night vision due to cataracts. “Other uses include treating attention deficit-hyperactivity disorder (ADHD), blunted sense of taste (hypogeusia), ringing in the ears (tinnitus), severe head injuries, Crohn’s disease, Alzheimer’s disease, Down syndrome” (WebMD).

Overall, Poliquin states, “Zinc is so important because it is found in every tissue in the body and is directly involved in cell division. It is a powerful antioxidant, helping to prevent cancer, but zinc also is directly involved in proper endocrine function and the maintenance of ideal hormone levels”.


One benefit is that Zinc is used to treat diarrhea in children. It is also used to boost immunity and prevent cancer (Poliquin). Other benefits include decreasing risk of Alzheimer’s disease. This antioxidant allows for toxins to be removed from the body as opposed being built up in tissue causing damage. Poliquin states, “The progression of neurodegeneration and Alzheimer’s disease is accelerated by heavy metal buildup in the brain. Zinc can help get rid of those toxins and it also helps maintain cellular homeostasis of brain cells.” Lastly, Zinc can have a protective effect by preventing high cholesterol and inflammation which can lead to heart disease (Poliquin).

Side Effects:

According to WebMD, “Taking high amounts of zinc is likely unsafe. High doses above the recommended amounts might cause fever, coughing, stomach pain, fatigue, and many other problems.” Also use Zinc on intact skin. Broken skin may cause burning, stinging, itching, and tingling.
