The Role Of Iron In The Body

Iron is an essential mineral and is vital for many complex processes and functions.

Iron is an essential mineral and is vital for many complex processes and functions in the body. Iron contributes to:

  • Normal formation of red blood cells and haemoglobin
  • Normal oxygen transport in the body
  • Normal energy-yielding metabolism (helping our body’s release energy from food)
  • Normal function of the immune system
  • Normal cognitive function
  • The reduction of tiredness and fatigue

Read on to find out the role of iron in the human body.

  • Iron helps oxygenate the blood
    One of the most important functions of iron is in heme synthesis, which forms haemoglobin, a protein found in red blood cells. Haemoglobin’s primary role is to transport oxygen from the lungs to body tissues to maintain basic life functions. Without healthy red blood cells, your body can't get enough oxygen and this can result in you feeling tired.


  • Iron helps convert food to energy
    Our bodies need iron to convert food to energy. Iron plays a vital role in the process by which cells generate energy. Human cells require iron in order to convert biochemical energy from nutrients into ATP (Adenosine Triphosphate) from a multi-step process known as cellular respiration; ATP is the body’s primary energy source.  Without any iron no ATP can be produced, which is another reason why those lacking iron are easily tired and fatigued. 


  • Iron helps maintain a normal immune system
    Iron is necessary for immune cells proliferation and maturation, particularly lymphocytes, which are associated with helping us to keep healthy. 


  • Iron contributes to normal cognitive function
    Iron plays an important role in maintaining normal cognitive function. Cognitive function includes brain functions such as memory, attention (concentration), alertness, learning, intelligence, language, and problem solving.


As our bodies do not produce iron we need to make sure we include sufficient iron as part of our healthy diets.  Some peoples’ lifestyles can mean that they struggle to get the iron they need from their diet alone. Spatone® Liquid Iron food supplement can provide your body’s daily iron.
