Inhibiting Dietary Iron Absorption in Subjects With Hereditary Hemochromatosis by a Natural Polyphenol Supplement

Testing the Efficacy of a Natural Polyphenol Supplement to Inhibit Dietary Iron Absorption in Subjects With Hereditary Hemochromatosis: a Stable Isotope Study

Polyphenolic compounds are very strong Inhibitors of non-heme iron absorption, as they form insoluble complexes with ferrous iron. Patients with hereditary hemochromatosis (HH) have an increased intestinal non-heme iron absorption due to a genetic mutation in the regulatory pathway, leading to excess iron in the body. This study investigates the inhibitory effect of a natural polyphenol Supplement in participants with HH.
