Small quantities of zinc in the form of oligo-elements occur naturally in the human body. Zinc is essential in the formation of over 200 enzymes responsible for the metabolism of lipids, sugars, proteins and nucleic acids in the human body.
Zinc is found mostly in foods rich in animal proteins such as: eggs, meat, dairy products, fish and oysters (80 mg for 100 g).
Zinc is required throughout the entire life, whether during pregnancy, youth, middle or old age. Studies have shown the usefulness of zinc supplements for the immunity and nutrition of seniors.
Zinc deficiency will result in immunity problems.
Zinc… how and when?
In the human body zinc is found mostly in muscles (60%) and in bones (30%). Normal daily nutrient requirements are 15 mg of zinc. A healthy diet will contribute between 8 and 11 mg of zinc on a daily basis.
Alcohol and tobacco consumption will also result in higher needs for zinc.
Zinc is an oligo-element essential to maintain the immune system. Its effects on the skin, hair, memory and physical performance are evident. The contribution is useful throughout all phases of life and particularly for those older subjects more exposed to deficiencies.
US National Institute of Health (NIH) refers to approximately 100 enzymes.
US NIH recommends between 8 and 11 mg of zinc daily, up to 13 mg for lactating or pregnant women. (See reference 2 above)
