Zinc

What is Zinc?

Zinc is an essential mineral involved in a wide range of vital bodily functions. Severe Zinc deficiency is rare. Zinc and Copper are closely linked in the body: high intakes of Zinc can reduce how much Copper is absorbed, which is why the two are often balanced together.

What does Zinc do?

Zinc is crucial for our immune system: Zinc contributes to the normal function of the immune system, and it affects the immune system in multiple ways. Zinc is central to the normal development and function of 'neutrophils' and NK ('Natural Killer') cells, which are part of our innate immunity. Neutrophils are a type of white blood cell that are often the first to arrive where the immune system is active, and NK cells respond later. Zinc is needed for the regulation and maturation of neutrophils and NK cells. Researchers have described Zinc as a gatekeeper of immune function, and have also looked at Zinc as an essential micronutrient and its wider roles in the body.

Zinc also has antioxidant activity, and Zinc contributes to the protection of cells from oxidative stress. Oxidative stress is the state of having too many 'free radicals' (unstable molecules that can damage cells). Some immune cells release reactive chemicals when they come into contact with a pathogen (a germ), which is one reason the balance of oxidation matters to the immune system.

Zinc contributes to normal DNA synthesis, which is needed for normal DNA replication, and has a role in the process of cell division. Each time a skin cell divides, it needs Zinc to copy its DNA. Zinc contributes to the maintenance of normal skin, hair, nails and bones.
