Our body does not allow free ionic iron circulating in the blood because the iron ion is the link that allows attachment of viruses and bacteria to our cells’ walls.
OUR BODY MAKES USE OF TWO PROCESSES:
1. Neutralization of ionic iron by chelation
2. When there is a shortage of lactoferrin, the liver begins to produce the molecule hepcidin, which closes the iron channels on the intestinal cells leading to decrease in hemoglobin and growth of deposits of iron (ferritin).
Low level of hepcidin (hypoxia, decreased ferritin). The liver releases iron in the blood through ferroportin.
High concentration of hepcidin (inflammation, increased ferritin) released by the liver. The release of iron in the blood is prevented by the blocking of ferroportin.
