Recent research on iron deficiency reveals intermittent iron supplementation offers no absorption advantage. The serum transferrin receptor shows promise for assessing iron status and differentiating anemias.

Area of Science:

  • Hematology
  • Nutritional Science
  • Clinical Medicine

Background:

  • Iron deficiency is a global health concern impacting various populations.
  • Understanding iron metabolism is crucial for diagnosing and managing anemia.
  • Current methods for assessing iron status have limitations.

Purpose of the Study:

  • To review recent advancements in iron deficiency management and assessment.
  • To evaluate the efficacy of intermittent iron supplementation.
  • To explore novel biomarkers for iron status evaluation.

Main Methods:

  • Review of current literature on iron supplementation, absorption regulation, and biomarkers.
  • Analysis of radioiron absorption studies on intermittent iron dosing.
  • Discussion of the role of serum transferrin receptor in iron status assessment.

Main Results:

  • Intermittent iron supplementation (once or twice weekly) demonstrated no significant absorptive advantage over daily dosing.
  • Prophylactic iron supplementation in elderly blood donors provided limited benefit for donation frequency.
  • The serum transferrin receptor is a valuable tool for distinguishing iron deficiency anemia from anemia of chronic disease.

Conclusions:

  • Daily iron supplementation remains the standard for maximizing absorption.
  • The serum transferrin receptor offers a reliable method for assessing functional iron deficiency.
  • Further research into iron absorption regulation and non-hematopoietic effects is warranted.
