Iron is an essential part of hemoglobin, which is found in red blood cells and carries oxygen throughout the body. Most of the iron outside of hemoglobin is stored as ferritin, a complex of iron and a protein that can be used to screen for iron deficiency¹. The ferritin test is a specific and sensitive measurement of your iron levels.
Pregnant women, children, and vegetarians have a higher risk of becoming iron deficient. Having an elevated ferritin level is far less common and may be a symptom of liver disease, hyperthyroidism, or infection.
Low iron can cause fatigue, headaches, and dizziness. It also increases your risk of developing anemia, a condition characterized by having too few functional red blood cells².
