Next to iron, zinc is the most common mineral in the body and is found in every cell. It has an important role in the workings of the muscular system, reproductive systems in both men and women, and proper insulin and thyroid function. It is one of the main minerals I recommend to boost the quality of sperm in my fertility patients. Zinc is also a catalyst for the vitality of the skin and wound healing. However, zinc is probably best known for supporting the healthy functioning of the immune system.
Several studies have shown that zinc lozenges or syrup reduced the length of a cold by one day, especially when taken within 24 hours of the first signs and symptoms. Studies also show that taking zinc regularly might reduce the number of colds each year, the number of missed school days, and the amount of antibiotics required in otherwise healthy children. New studies are also looking at how the body uses zinc and whether or not taking zinc can improve the treatment of celiac disease, diabetes, and inflammatory bowel disease.
There are several forms of zinc, but not all are easily absorbed or appropriate for every person. The two best forms are zinc gluconate, and zinc citrate. According to the National Academy of Health Sciences, the need for a zinc supplement varies based on age, gender, pregnancy status, and other health factors. Zinc can interfere with the actions of some medications and can even affect the utilization of other minerals, such as copper. It’s best to first consult with your wellness practitioner before taking zinc.
Though we recognize zinc as an immune stimulant, care needs to be exercised as too much zinc may actually inhibit immune function as well. Zinc can be dosed orally, taken through lozenges, or at times we place zinc in IVs to boost a patient’s immune system in times of sickness.
