Pre-clinical study shows heme iron polypeptide corrects anemia in rodents, indicating its potential for treatment.

The study aims to clarify the mechanisms of heme iron absorption and its effectiveness in treating iron-deficiency anemia.
Utilized a nutritional paradigm with pre-clinical rat and mouse models.
Formulated diets containing heme iron polypeptide, non-heme iron, and heme-enriched diets.
Applied a classic depletion/repletion design over 24-28 days.
All diets effectively corrected anemia in iron-depleted rats and mice.
Erythropoietic biomarkers normalized with heme iron polypeptide.
Heme iron polypeptide showed a high enrichment of heme iron.

He et al. (2026) studied this question.
