Experts Warn Iron Doses Above 120 mg Can Damage Organs

Summary
Single iron doses above 120 mg of elemental iron are likely excessive, hematologists said, warning that people often self-supplement without confirming they are actually iron deficient.
A common treatment dose for confirmed iron deficiency is 65 mg daily, while pregnant people may need about 27 mg; experts said routine oral iron more than once a day adds no benefit.
Blood tests are the key check because fatigue and low-energy symptoms can stem from other conditions, including thalassemia or myelodysplastic syndrome, that will not improve with iron supplements.
Excess iron can first show up as constipation, nausea, stomach upset and dark stools, but prolonged overload may build up in the liver and heart, leading to cirrhosis or heart failure.
Iron deficiency still affects about 14% of Americans, making doctors' monitoring of hemoglobin and ferritin levels critical to balance treatment benefits against overload risk.
