Zinc is a metal considered a trace element for humans. With a varied and balanced diet, the body usually gets enough zinc. Very low levels of this essential element circulate in our cells. It is involved in many different biochemical reactions, where it is used by hundreds of enzymes either as a cofactor or as a component.
All of the body’s cells and organs need zinc (for example, it is involved in the synthesis of DNA).
Zinc deficiency can occur with age or be caused by an unbalanced diet. After iron, it is the most abundant trace element in the body. That is why taking zinc is recommended in cases of temporary fatigue and during periods when the body is subject to more intense levels of external stress (viruses, bacteria, pollution, etc.).
In these cases, the body becomes more vulnerable. Zinc is indeed essential throughout the life cycle of immune cells, whether for their synthesis by bone marrow, their maturation or their healthy functioning.
Zinc is therefore necessary for both the effectiveness and modulation of immune defences. Zinc contributes to normal immune system function.
