Zinc is a trace mineral found in protein-rich foods such as pork, beef and peanuts. The recommended amount of zinc a person should consume daily is between 2 and 13 mg, depending on age, gender and medical condition, according to the Office of Dietary Supplements. Maintaining adequate intake of zinc is important because the body does not store the mineral efficiently. Not getting enough zinc in the diet may increase the need to take zinc supplements to treat possible complications associated with a deficiency in the mineral. Consult a health care professional before taking zinc to treat a medical condition.
Immunity and Healing
Zinc plays a role in the immune system's function by assisting the cells in the body responsible for fighting off viruses and bacteria. This mineral also helps maintain healthy skin. Low levels of zinc may increase a person's risk of developing infections such as pneumonia or wound infections on the skin. Taking zinc supplements may help shorten the symptoms and duration of the common cold, but there is no proven evidence to support the efficacy of using zinc supplements.
Skin Conditions
Using zinc supplements may help a variety of skin conditions. Applying zinc directly to the skin may help treat acne, improve aging skin and ease the symptoms of a herpes simplex infection, which causes sores on the mouth. Zinc may help wounds heal, especially after surgery or a burn, according to the Mayo Clinic website.
Wilson's Disease
Wilson's disease is a rare medical condition that causes the body to store too much copper. The excessive amounts of copper may damage the nervous system and the liver. Symptoms of Wilson's disease include jaundice, dementia, still arms and legs, a distended abdomen, slow movements, and tremors. Copper is in foods such as chocolate, nuts and shellfish. Taking zinc supplements may help treat Wilson's disease because zinc helps block the absorption of copper in the intestinal tract, according to MedlinePlus.
Diarrhea
Taking zinc may help treat diarrhea in children who are older than 6 months. Taking zinc supplements may help shorten the duration of the condition but may also increase the likelihood of vomiting, according to Drugs.com.
Treating and Preventing Zinc Deficiency
Risk factors for not getting enough zinc through the diet include alcoholism, consuming a vegetarian diet and having gastrointestinal surgeries, which may cause a decreased absorption of zinc. A deficiency in zinc may cause symptoms such as slow growth for children, impotence for men, hair loss, diarrhea, decreased appetite, weight loss, and a decreased sense of taste and smell. Taking zinc supplements may help improve these symptoms.
