Proferrin is an oral heme iron polypeptide (HIP) supplement derived from bovine hemoglobin. It provides elemental iron in a heme form designed for efficient absorption.

What is Proferrin used for?

It is used to help treat iron deficiency and iron deficiency anemia by supporting hemoglobin and iron stores such as ferritin. It may be considered when non-heme iron supplements are not well tolerated or effective.

How much Proferrin should I take?

Common supplemental dosing provides about 11–33 mg of elemental iron per day, depending on individual needs and product strength. Follow the product label and clinician guidance, especially if you have anemia or chronic conditions.

Does Proferrin cause fewer stomach side effects than other iron supplements?

Many people report fewer gastrointestinal effects such as constipation, nausea, or stomach discomfort compared with traditional iron salts. Individual tolerance can vary.

Who should be cautious with Proferrin?

People with iron overload disorders or those advised to avoid iron should not use it unless directed by a clinician. Because it is bovine-derived, it may not be suitable for individuals avoiding animal products or with specific allergies.
