Is there a danger of iron toxicity?
The danger of iron toxicity is rare due to fact that iron absorption is closely regulated and decreases when iron stores are full. A genetic defect called hemochromatosis, most common in men, causes excessive iron absorption and may result in damage to the heart, liver, spleen, and pancreas. Iron supplements are hazardous for children to ingest and should be kept out of the reach of children.
