What is zinc? Learn more about zinc and its essential role in the human body.
Zinc comes in several forms. It is known by the following names, zinc amino acid chelate, zinc gluconate, zinc sulfate and zinc chloride. Typically supplementation is in the form of zinc sulfate.
The dietary sources for zinc are typically among natural, unprocessed foods. Zinc is available in both plant and animal dietary sources. It is more readily absorbed from animal sources than plant sources. The best sources for this mineral are meat and other protein rich foods. Seafood is an excellent dietary source of zinc. Whole grain breads, cereals and dried beans are also fantastic sources of zinc.
Zinc’s primary function in the human body is to manufacture proteins and nucleic acids (what is known as the “general” material cells are made of). Zinc is also essential in the role of over 100 enzymatic functions in the human body. It is also intergral to a normal growth and developmental rate, as well as in the development of both male and female reproductive organs. Zinc is involved in the functioning of insulin in the body and in the utilization of carbohydrate stores. Zinc also assist in healing through aiding wounds and burns and has a part in the healthy functioning of the prostate gland.
Even though it is so important to proper functioning of the human organism, zinc deficiency does occur but typically only in the elderly and other such populations that tend to be malnoursihed. Severe zinc deficiency often causes poor growth and may contribute to delayed sexual development or dwarfism. A prolonged lack of zinc intake may lead to symptoms such as rash, inflamed areas of skin, hair loss, or pustules in the mouth, tongue and eyelids and even around fingernail beds.
Recommended intakes of zinc vary depending on severity of insufficiency, however the consensus among professionals seems to be between 30 to 50 milligrams daily. Of course, before starting any form of supplementation you should consult your health care practitioner.
