Iron is one of the essential trace minerals. Iron absorption in the body is increased when it is consumed together with vitamin C. Dairy products, coffee or black tea, on the other hand, impair iron absorption when ingested at the same time.

The mineral contributes to
- normal formation of red blood cells and haemoglobin
- normal oxygen transport in the body
- normal energy-yielding metabolism
- normal cell division
- the reduction of tiredness and fatigue
- a normal function of the immune system
- normal cognitive function

The following groups of people may have higher iron requirements:
Children and adolescents, women, pregnant and breastfeeding women, athletes and vegetarians.
