Heme iron polypeptide supplies elemental iron in a heme-bound form that is absorbed through pathways partly distinct from non-heme iron. Iron supports hemoglobin and oxygen transport, but supplementation is useful only when intake or iron status warrants it.
What it is, why people use it, the evidence, and what to know before trying it.
Known side effects, interactions and use limits from reviewed sources.
Iron can cause gastrointestinal symptoms and dangerous overdose, especially in children. Excess iron can damage organs; avoid unsupervised use with hemochromatosis or normal or high iron stores. Iron interacts with levothyroxine and some antibiotics, so separation and clinician or pharmacist review may be needed. The product is bovine-derived.
