First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether daily iron supplements can improve restless sleep and ADHD symptoms in 70 children with ADHD who have low iron levels. Participants will take either iron or a placebo for 3 months, and their sleep and attention will be measured using motion-sensing leg bands and questionnaires. The goal is to see if a simple, over-the-counter supplement can make a real difference.
