Zinc plays an important role in growth, immune response, the neurological and reproductive functions. It is necessary to over a hundred processes and vital enzymes in the body (the experts estimate 300). It participates in the synthesis of DNA, RNA and proteins, the immune process and healing, reproduction and growth. It plays a role in modulating mood and learning, as well as chapters of vision, taste and smell. It intervenes in the process of blood clotting, the functions of thyroid hormone and in the metabolism of insulin.
What is zinc ?
Zinc is a trace element, that is found only in trace amounts in the body, the equivalent of about 2 g in all, including 65% are concentrated in the muscles and 20% in the bones. It is present in all cells, especially in the adrenal glands, skin, parts of the brain, pancreas, membranes of the eye, prostate and sperm. It would be necessary to over a hundred process vital enzyme in the body (the experts estimate that 300). It participates in the synthesis of DNA, RNA and proteins, the immune process and healing, reproduction and growth. It plays a role in modulating mood and learning, as well as chapters of vision, taste and smell. It intervenes in the process of blood clotting, the functions of thyroid hormone and in the metabolism of insulin.
Why take zinc ?
The zinc deficiency can cause growth retardation, abnormalities of sexual maturation, taste disorders, immune problems, skin problems and healing. It is an antioxidant that intervenes indispensable in preventing toxic effects caused by free radicals. In inflammatory acne, zinc has demonstrated efficacy equivalent to tetracycline, an antibiotic used to treat acne.
A report published in the Archives of Ophthalmology in October suggests that the administration of high doses of antioxidants (vitamins C and E and beta-carotene) combined with a supplement of zinc can slow or even prevent the loss of vision caused by macular degeneration related to age.
The study assessed the effect of high doses of antioxidants and zinc on the development of macular degeneration at an advanced stage with seniors. Participants aged 55 to 80 years were divided into four groups. They were randomly every day is a mix of antioxidants consisting of 500 mg of vitamin C, 400 IU of vitamin E and 15 milligrams of beta-carotene, or 80 mg of zinc or zinc oxide and copper, or 2 mg of copper oxide, or a mix of antioxidant vitamins in combination with zinc and a placebo. Although the doses are greater than the usual recommended dose, researchers have found no significant side effects.
Research results show, among subjects who received a mix of vitamins and zinc, a decrease of 25% of the risk of aggravating the disease and a 19% reduction in risk of losing sight Compared to placebo.
Thus, if the seven million people suffering from macular degeneration took at the intermediate stage of the disease, a mix of antioxidants with zinc for a period of five years, nearly a quarter of a million people could avoid blindness.

Related macular degeneration age is the most common cause of loss and blurred vision in people aged 65 and over. In the first stage of the disease, there is a deposit formation called "Druze" in the macula - the central part of the retina behind the eyeball. In the form "dry" of the disease, the photoreceptors (cells sensitive to light) degrade and disrupt the acuity of vision. The form "wet" (less common but more serious) is characterized by the formation of blood vessels behind the retina may elapse and the rapidly deteriorating vision. The methods used to treat the wet form are laser photocoagulation or use of substances sensitive to the laser.
Until this latest study, there was no therapy for the dry form of macular degeneration. The results are promising enough to recommend taking antioxidants and zinc for all subjects at the intermediate stage of the disease. As against, is not recommended for people at risk or in the first stage of the disease to take high doses of supplements because the data do show any benefit at this stage of degeneration, or evidence of any risk of side effects long term. It strongly recommends people 55 and older to undergo screening as a preventive measure.

Zinc is a trace element essential to the smooth functioning of the body:
• treats acne
• Reduces the duration and symptoms of colds
• Treats taste disorders
• Slows Macular Degeneration
• Reduces the sensitivity to infections of people with sickle cell anemia.
