Most people would consider calcium, sodium and iron, to be essential minerals and usually forget about zinc.

Zinc happens to be a very important mineral not only to our metabolism, but also our health in many significant ways such as:

  • Sense of smell
  • Building of protein
  • Function of the Immune System
  • Creation of DNA
  • Metabolism of RNA and DNA
  • Gene Expression
  • Signal Transduction

And those are just some of the benefits, but the downside to zinc deficiency can also trigger many problems.

Those zinc deficiency can lead to complications such as:
