Iron metabolism comprising a series of processes, such as:
- Regulation of iron intestinal absorption;
- Transport of iron to cells;
- Iron storage;
- Incorporation of iron in the proteins;
- Iron recycling after degradation of erythrocytes.
In general, iron’s absorption is controlled at intestinal level.
In the process of iron metabolism there is an average loss of 1-2 mg a day that It should be recovered through foods.
