The Effect of Iron Deficiency Anemia and Serum Ferritin Deficiency on Cognitive Functions in Children 1 to 5 Years Old.

Human

2025 Aug 4

This study found that young kids with low iron stores (measured by serum ferritin) had worse thinking and movement skills, and when they got iron treatment, they got better — so low iron early on really does hurt brain and body development in toddlers.
