Zinc – biological role and relevance in the context of testosterone

What is zinc?

Zinc is a chemical element with the symbol Zn, classified as a trace element. It is present in small amounts in living organisms, yet it is essential for the proper functioning of many biological processes. From a biochemical perspective, zinc acts as a cofactor for numerous enzymes and contributes to the structural integrity of cells. As a mineral nutrient, zinc must be regularly supplied through the diet.

Biological role of zinc

Zinc helps maintain normal testosterone levels in the blood. This function is recognized within authorized nutritional claims. Beyond this role, zinc is commonly described in nutrition science as a trace element involved in a wide range of metabolic processes at the cellular level, which explains its importance in human physiology.

Scientific background and research

Zinc has been extensively studied over many years. Scientific publications examine its bioavailability, metabolism, and role in biological systems. In the context of hormonal balance, zinc is described as a nutrient relevant to maintaining normal physiological parameters. Research on zinc is conducted in fields such as biochemistry, nutrition science, endocrinology, and food science, and focuses on analytical and descriptive findings.

Dietary sources of zinc

Zinc occurs naturally in a wide variety of foods of both animal and plant origin. Major dietary sources include meat, fish, seafood, whole grains, nuts, seeds, and legumes. The zinc content of foods is documented in nutritional databases and food composition analyses.
