There are two types of iron – ionic iron and heme iron polypeptide (HIP). Proferrin® is the only iron supplement made in the U.S. that uses no ionic, only heme iron polypeptide. Read throughout this site how HIP (the active ingredient in Proferrin®) can help you maintain serum iron levels with fewer side effects.*
Choose the iron that works with your body, not against it.
EXPERIENCE THE PROFERRIN® DIFFERENCE
Absorbing iron orally is difficult and Proferrin® helps solve this problem. A study performed at the University of Colorado compared taking 20 mg of elemental iron as heme iron polypeptide to taking 20 mg of ionic iron (ferrous fumarate) with a standard meal. The study demonstrated that HIP increased serum iron levels 23 times greater than ionic iron on a milligram-per-milligram basis.1
Contains Only Iron from Natural Sources*
The HIP in Proferrin® is extracted from hemoglobin, a naturally occurring iron source found in red meat and poultry.2 Heme iron sources used by Proferrin® do not contain common allergens, such as milk or wheat products, gluten, or significant amounts of oils or fats. If you have specific allergies, please contact your physician or Colorado Biolabs for more information.
Doesn’t Compete with Other Nutrients*
The HIP found in Proferrin® is absorbed differently than traditional irons. Unlike other irons, Proferrin® does not compete with other nutrients.3,4
Fewer Dosing Restrictions*
HIP does not appear to be affected by calcium, coffee, or other foods, and can be taken with meals.1 It may even replace intravenous irons.5
Fewer Side Effects*
Traditional iron supplements are made with ionic irons, which can cause side effects such as constipation, cramping, gas and other forms of digestive system problems.6,7,8 Proferrin® causes less gas 9 and is unlikely to cause common iron-related digestive system side effects. This is due to Proferrin’s® heme iron polypeptide being absorbed differently than that of non-heme iron.
If you take a traditional iron supplement to get your Recommend Daily Allowance (RDA), then you may be totally missing the target. The USDA recommendations assume that 75 percent of your daily iron comes from heme Iron sources rather than non-heme iron.
