Many multivitamins list elemental iron, but heme iron polypeptide (derived from hemoglobin) is absorbed up to three times more efficiently and causes fewer gastrointestinal side effects than typical nonheme iron salts; however, heme forms are less common due to higher production costs and sourcing constraints. Choosing the iron form affects both efficacy and tolerability, not just the milligram amount on the label.
Esmond Natural USA prioritizes well-tolerated, bioavailable iron options to balance absorption with digestive comfort.
