More About Colorado Biolabs
In 1997 Colorado Biolabs Inc set out to develop and market an oral iron supplement from heme iron polypeptide. Their research and hard work eventually produced Proferrin ES, a quality iron supplement.
Iron is an important mineral involved in the transportation of oxygen and carbon dioxide. Many may suffer from low iron levels and not even know it.
Proferrin ES is Colorado Biolabs' main product. Proferrin ES is a unique heme iron polypeptide supplement. Heme iron polypeptide is great for individuals who are prone to iron deficiency.
