Required for proper functioning of genetics, immunity, formation of red blood cells, organ, muscle and bone function, cell membrane stability, cell growth, division, differentiation and genetics.

Importantly, zinc is vital for the metabolism of vitamin A.

To much zinc can do damage and stimulate cancer development.
