What is the daily recommended elemental iron supplementation for infants when intake is determined to be insufficient?

The daily recommended elemental iron supplementation for infants, particularly when dietary intake is determined to be insufficient, is set at 1 mg/kg/day. This dosage is based on recommendations from various pediatric associations and guidelines that recognize the importance of sufficient iron intake in infancy for proper growth and development.

Iron is essential for the formation of hemoglobin, and infants require adequate amounts to support their rapid growth and increased blood volume. While sources of iron can be obtained through dietary means, many infants, especially those who are exclusively breastfed or on low-iron formulas, may require supplementation to prevent iron deficiency anemia.

Choosing a supplementation amount of 1 mg/kg/day aligns with the established guidelines for most full-term infants, as this amount has been shown to effectively meet the iron needs of infants who are at risk of deficiency without causing adverse effects. Higher dosages may carry risks of iron overload or gastrointestinal side effects, which is why the recommended dosage is precisely calibrated to ensure safety and efficacy in this vulnerable population. This approach ensures that infants can achieve optimal iron status while minimizing the risk of complications associated with excessive supplementation.
