What is Elemental Iron? Elemental iron is the iron in a supplement that is readily absorbable. Your supplement should list the percentage of elemental iron right on the label for you so you don't have to calculate it yourself. Supplements have either ferrous or ferric iron, with ferrous having more elemental iron ready for absorption. Ferrous iron supplements with the most elemental iron come in ferrous fumarate, ferrous sulfate or ferrous gluconate forms.
