Zinc

Zinc is a metal. It is called an “essential trace element” because very small amounts of zinc are necessary for human health.

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.

It is also used for boosting the immune system, treating the common cold and recurrent ear infections, and preventing lower respiratory infections. It is also used for malaria and other diseases caused by parasites.

Some people use zinc for an eye disease called macular degeneration, for night blindness, and for cataracts. It is also used for asthma; diabetes; high blood pressure; acquired immunodeficiency syndrome (AIDS); and skin conditions such as psoriasis, eczema, and acne.

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, Hansen’s disease, ulcerative colitis, peptic ulcersand promoting weight gain in people with eating disorders such as anorexia nervosa.

Some people use zinc for benign prostatic hyperplasia (BPH), male infertility, erectile dysfunction (ED), weak bones (osteoporosis), rheumatoid arthritis, and muscle crampsassociated with liver disease. It is also used for sickle cell disease and inherited disorders such as acrodermatitis enteropathica, thalassemia, and Wilson’s disease.

Some athletes use zinc for improving athletic performance and strength.

Zinc is also applied to the skin for treating acne, aging skin, herpes simplex infections, and to speed wound healing.
