Zinc is a trace element essential for the proper functioning of many functions in the human body, including growth, immune response, neurological and reproductive functions. It is involved in more than a hundred vital enzymatic processes. In addition, zinc plays a crucial role in thyroid function, insulin regulation, spermatogenesis and is one of the antioxidant molecules. It should be noted, however, that high zinc supplementation (100 mg) may have anti-aromatase effects, slowing the conversion of testosterone to estrogen. It is important not to take excessive doses of this trace element.

An adequate daily intake of zinc can provide benefits for skin and hair health, in addition to optimizing the healing process. Zinc also promotes the synthesis of prostaglandins, substances with anti-inflammatory properties.

Zinc is often used to treat taste disorders and can have a beneficial impact on the preservation of the taste and olfactory senses.

It should be noted that zinc is a relatively sensitive trace element, and certain food sources, such as animal proteins, can promote its assimilation. On the other hand, the consumption of whole grains can significantly reduce its absorption.

The best food sources of zinc include oysters, red meats, sesame seeds, legumes and pumpkin seeds.

Several scientific studies have been carried out to evaluate the effects of zinc on health. Research has shown its involvement in the regulation of the immune system, wound healing, skin and hair health, as well as the preservation of taste and olfactory functions. However, further research is needed to fully confirm these benefits and determine optimal doses.
