Iron

Iron is an essential heavy metal that is included in many over-the-counter multivitamin and mineral supplements and is used therapeutically in higher doses to treat or prevent iron deficiency anemia. When taken at the usual recommended daily allowance or in replacement doses, iron has little or no adverse effect on the liver. In high doses and in intentional or accidental overdoses, iron causes serious toxicities, one component of which is acute liver damage. — LiverTox
