What is ferritin?
Ferritin is a protein molecule in which iron is stored. Most ferritin is found in the liver, spleen and bone marrow. A small amount of ferritin travels in our bloodstreams and is a proxy for all ferritin in iron diagnostics. So when ferritin is measured in the blood, this value indicates how well your iron stores are filled overall, and thus whether you may be deficient or oversupplied.
What functions does iron perform in the body?
The most important function that iron performs is the formation of hemoglobin, a protein in red blood cells. As the largest component of this protein, iron not only gives the red blood cells their red color but also enables the transport of oxygen. Iron also plays an important role in the immune system. The production of immune cells is stimulated by iron and thus helps to protect you from pathogens. In the muscles, iron ensures better performance and allows higher strains. This also applies to the brain if the nerves are supplied by the iron with enough oxygen. With a balanced iron balance, you thus gain in performance and cognitive skills such as concentration get easier.
How does iron deficiency develop?
We speak of an iron deficiency when the daily intake of iron cannot cover the demand. If this imbalance persists over the long term, iron stores become increasingly depleted and the body gradually loses its performance capacity. There are various causes that can lead to such an imbalance and to an iron deficiency. Basically it is due to the fact that
  • too little iron is absorbed an unbalanced diet (vegan, vegetarian), digestive disorders, chronic diseases
  • there is a higher need for iron pregnancy, breastfeeding, growth phases, competitive sports
  • the body loses too much iron menstruation, blood donation, internal bleeding
