Iron is a trace mineral that plays an important role in our basic life functions and is very essential for our survival. It is one of the most abundant elements on Earth where it became very significant since ancient civilizations until today. This mineral is necessary for basic cellular and tissue functions and is required for the proper functioning of your muscles, brain and red blood cells.
The trace mineral is not made in the body that's why we need to supply it with the foods that we eat, where only 10 to 30 per cent of the iron we consume is absorbed and used by our body.

The largest use of iron is the manufacture of steel which is an iron-carbon alloy that is necessary for the construction of buildings.
