Zinc, the second most prevalent element in the body, is critical for immune system health and growth. As important as this mineral is, though, the body needs only 8 to 15 mg a day. Zinc deficiency is rare in developed countries, but the elderly and those with conditions that interfere with nutrient absorption may become deficient. Foods rich in zinc include oysters, red meat, legumes and some cheeses like ricotta and gouda.
Faster Wound Healing
Zinc is an important part of the enzymes needed for cell reproduction and wound healing. Taking 50 mg of zinc 3 times a day increased surgery wound healing time by 43 percent, a 1967 study from the Massachusetts Institute of Technology found. Although later research results have been inconsistent, medical professionals sometimes recommend zinc supplements for quicker healing. For minor cuts and scrapes, apply an ointment that contains zinc along with chondroitin sulfate or gotu kola, recommend experts from the University of Michigan.
Clearer Skin
Zinc appears to ease rosacea symptoms and may help clear up acne, as well. Rosacea patients who took 100 mg of zinc sulfate 3 times a day saw their symptoms, such as facial redness, reduced by around 75 percent, discovered a small study published in the "International Journal of Dermatology" in July 2006. A combination of topical zinc and the antibiotic erythromycin may also reduce acne. For acne, results with zinc supplements have been inconsistent.
Fewer Cold Sores
The herpes simplex virus causes cold sores on the lip, but zinc preparations may offer one way to heal them or prevent them altogether. Study participants who applied a glycerin-based zinc oxide cream at the first sign of a cold sore noticed their symptoms were significantly less severe and the blisters healed a day and a half sooner. To treat cold sores, try a commercial cream containing zinc oxide.
