What is Proferrin-ES?

Proferrin-ES is a type of iron. You normally get iron from the foods you eat. In your body, iron becomes a part of your hemoglobin (HEEM o glo bin) and myoglobin (MY o glo bin). Hemoglobin carries oxygen through your blood to tissues and organs. Myoglobin helps your muscle cells store oxygen.

Proferrin-ES is used to assist in maintaining iron levels.

Proferrin-ES may also be used for purposes not listed in this medication guide.
