Iron plays such a huge role for energy, adequate iron levels are critical for excellent thyroid function and therefore energy, but iron alone also impacts on energy levels, predominantly via it's role in oxygen transportation.
Iron deficiency anaemia can be caused by;
- Inadequate dietary intake of iron
- poor absorption of iron
- loss of iron due to bleeding (menstruation or blood loss from the gut).
Heavy menstrual blood loss is a common cause, as are increased demands for iron during pregnancy. In pregnant women, iron stores have to serve the increased blood volume of the mother, as well as the needs of the growing baby.
