Proferrin® ES is the original heme iron supplement. It contains Heme Iron Polypeptide, a natural form of iron found in meat. Compared to other forms of iron, it has 10-23x higher absorption 1, can be taken with or without food, coffee, calcium, or Vitamin C, and is not affected by PPIs*.
Proferrin® Clear is our all-natural option for those that don’t prefer tablets or color dyes. It contains the same amount of heme iron as Proferrin® ES; however, it comes in a dye-free gel capsule form rather than a tablet. It is a simple yet effective product with only four ingredients.
Proferrin® Forte was designed for those who need a little more iron and can benefit from the folic acid provided by our unique formula. It comes in a coated tablet form like Proferrin® ES but contains 1.5 mg more of heme iron than either ES or Clear, for a total of 12 mg, and it also contains 1000mcg (1667 mcg DFE) of folic acid.
