Can starting iron sooner protect preterm babies on donor milk?
NCT ID NCT07816601
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
Very preterm infants fed donor breast milk can run low on iron because donor milk has less of it than formula or fortified feeds. This trial tests whether starting an oral iron supplement earlier, once an infant tolerates 80 ml of milk per kilogram per day instead of waiting for full feeds, raises iron stores and red blood cell levels. Researchers will measure ferritin and hematocrit in 17 infants born between 29 and 32 weeks of gestation at about 14 and 28 days of life. The goal is to see whether earlier iron helps this vulnerable group avoid iron deficiency anemia.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ferrous sulfate, an oral iron supplement
- What this could lead to
- If it works, this could give neonatal units a simple way to protect preterm infants on donor milk from iron deficiency, which can affect growth and brain development.
- What could go wrong
- The trial is small, with 17 infants, and measures iron and hematocrit levels rather than long-term health outcomes. Early iron may not raise ferritin enough, and preterm infants can face feeding problems or other complications that disrupt the protocol.
