Zinc is one the micro-elements essential for the proper function of the body. It is required for the activity of over 200 different enzymes including those involved in protein, DNA and RNA synthesis. It is also responsible for correct division of cells. For this reason, it is particularly important for the development of the foetus (it may prevent defects of the neural tube, for instance). An important role of zinc is as well the maintenance of correct levels of vitamin A in blood plasma, which is crucial for healthy eyesight.
This trace element ensures a proper function of the skin and mucous membranes, hence it play a key role in keeping a healthy appearance. An easy to identify signal of its deficiency sent by our body can be skin imperfections or nails and hair that lose shine and become brittle. Zinc is essential for many hormones, for example the growth hormone or gonadotrophins — hormones responsible for healthy genital development (particularly in boys).
Zinc also contributes to the maintenance of normal testosterone levels in the blood, as well as contributes to normal fertility and reproduction.
Zinc is supplied to the body mainly in the diet. The largest amounts of this element can be found in calf, pork and chicken liver, seafood (e.g. oysters, crabs), legumes, wholegrain bread, pumpkin seeds, nuts, eggs, rennet cheeses, meat (especially red) and groats. Individuals at risk of zinc deficiencies are ones on a low-calorie diet, vegetarians, people consuming a lot of sweets, pregnant women, elderly and children.
In the case of zinc deficiency, apart from a well-balanced diet, supplementation may prove helpful. TIENS Zinc preparation helps maintain proper zinc levels in the body.
