Zinc is a micronutrient necessary for the proper functioning of the body. In the human body, it appears as a trace element, in the amount of only 1.5 to 2.2 grams. It occurs in tissues, blood, cells and bones. Zinc is a component of approximately 80 enzymes that are produced in our body. It participates in such processes as energy production, metabolism of proteins, fats and carbohydrates, protein synthesis and lysis, nucleic acid synthesis and amino acid production. Zinc is a microelement necessary for the proper development of the brain and function of the central nervous system, and its deficiency is associated with neurological dysfunctions. Zinc also has a protective effect on neurons and within the hippocampus against damage from quinoline acid. Quinoline acid is a powerful neurotoxin of the central nervous system, including secreted by the Borrelia bacteria.Too little zinc also increases the likelihood of depression and anxiety.

Zinc, like manganese or copper, is part of the superoxide dismutase (SOD) – one of the major antioxidants.

This element also affects the proper functioning of the immune system. Zinc stimulates thymus to secrete thymulin. This hormone is responsible for the production of T cells, immune cells directly involved in the fight against microorganisms. It also helps relieve the symptoms of autoimmune diseases.Furthermore, zinc makes it possible to maintain the optimal concentration of vitamin A in the blood and participates in the process of bone mineralization and tissue regeneration.
