First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at 830 two-year-olds in France to see if drinking toddler milk formula helps prevent iron deficiency, a common problem that can affect brain development. Researchers checked iron levels in blood and asked parents about diet and background. The goal is to find better ways to prevent and spot iron deficiency early.
