Zinc is a mineral essential to the body, zinc is a constituent of many enzymes that permit chemical reactions to proceed at normal rates. It is involved in the manufacture of protein (protein synthesis) and in cell division. Zinc is also a constituent of insulin, and is concerned with the sense of smell. Food sources of zinc include meat, in particular liver and seafood, eggs, nuts and cereal grains. Deficiency of zinc is associated with short stature, anemia, increased pigmentation of skin (hyperpigmentation), enlarged liver and spleen (hepatosplenomegaly), impaired gonadal function (hypogonadism), impaired wound healing, and immune deficiency. Too much zinc can cause gastrointestinal irritation (upset stomach), interfere with copper absorption and cause copper deficiency, and (like too little zinc) cause immune deficiency. The Recommended Dietary Allowance of zinc is 12 milligrams per day for women and 10 milligrams per day for men.(according to the National Academy of Sciences).

It's good for acne! Sadly I can't remember how much you need to take if this is your problem, so would recommend an internet search if you haven't already done so. But zinc supplements as well as a sugar free diet with lots of raw salads gave me a wonderfully clear skin in my early 20's when I was suffering from acne.
its good also for fertility and the production of healthy sperm
