It allegedly is more easily absorbed through cell walls. Ferrous sulfate is the most common & cheapest iron supplement but may not be well tolerated. Ferrous fumarate is better absorbed, but heme iron polypeptide is well tolerated & absorbed. Vitamin c enhances iron uptake.

Iron. Ferrous sulfate is also known as iron. You can use this as a supplement if your iron level is low- as a treatment for iron deficiency. Iron chelating agent- on the other hand- is used to bind the iron in your blood and then remove it from your body. This will be used if your iron level is too muc/highh- for instance in the setting where you received multiple blood transfusion.
