Description

Ludwig Svensson leads a 2026 randomised trial asking whether extra iron for breastfed babies affects behavior at age three. Breastfed infants can run low on iron, which the brain needs, but benefits in healthy infants are unclear. The trial ran in Warsaw, Poland, and Umea, Sweden.

Healthy full-term babies got a low daily iron dose or a placebo from 4 to 9 months of age. Of 221 babies randomised, 133 were assessed at age three with a child behavior checklist. The iron group scored lower for outward behavior problems, 45.6 against 48.6, and for aggressive behavior. The authors urge caution until other studies repeat the finding.
