As many as 80% of the world's population may be iron deficient, while 30% may have iron deficiency anemia [6]. 

Iron deficiency anemia can be associated with the following:

  • low dietary intake of iron
  • inadequate absorption of iron
  • excessive blood loss [1,5 ,7].


Women with heavy menstrual losses can lose a significant amount of iron and are at considerable risk for iron deficiency [1,2].

If you are concerned that you may be at risk for iron deficiency, talk to your healthcare provider
