Fe(III)-EDTA complex as iron fortification.

M Layrisse, C Martínez-Torres

    The American Journal of Clinical Nutrition
    |July 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Ferric iron-EDTA (Fe(III)-EDTA) offers superior iron absorption compared to ferrous sulfate for food fortification. This enhanced iron bioavailability can help prevent iron deficiency anemia in populations with vegetable-based diets.

    Area of Science:

    • Nutritional Science
    • Biochemistry
    • Public Health

    Background:

    • Iron deficiency anemia is a prevalent global health issue, particularly in populations reliant on vegetable-based diets.
    • Traditional iron fortification salts, such as ferrous sulfate, have limitations in bioavailability and can cause gastrointestinal side effects.
    • Ferric iron-EDTA (Fe(III)-EDTA) has emerged as a potential alternative for iron fortification.

    Purpose of the Study:

    • To evaluate the iron absorption and efficacy of Fe(III)-EDTA compared to ferrous sulfate for food fortification.
    • To determine the optimal dosage of Fe(III)-EDTA required to prevent iron deficiency anemia in specific populations.

    Main Methods:

    • Comparative study assessing iron absorption from Fe(III)-EDTA and ferrous sulfate in the gut lumen.

    Related Experiment Videos

  • Analysis of iron exchange with endogenous and exogenous food iron.
  • Dosage-response assessment for preventing iron deficiency anemia.

    • Main Results:

    • Fe(III)-EDTA demonstrated significantly higher iron absorption compared to ferrous sulfate.
    • Iron absorption from Fe(III)-EDTA was approximately double that observed with ferrous sulfate.
    • The study suggests that 10-15 mg of Fe(III)-EDTA fortification may be sufficient to prevent iron deficiency anemia.

    Conclusions:

    • Fe(III)-EDTA presents a more effective iron fortification strategy due to its enhanced bioavailability.
    • This iron compound facilitates better absorption of both intrinsic and extrinsic food iron.
    • Fe(III)-EDTA holds promise for public health interventions aimed at combating iron deficiency anemia, especially in vulnerable populations.
