A recent study from Radiology showed that iron absorption was abnormal (low) in patients with ADHD. This was based on 22 kids with it and 12 who never took any medications for it. There were 27 controls. It was coauthored by Helpern and Jensen (both PhDs). Of the kids with ADHD those on medication had higher iron levels than those who hadn't been on it. It was performed at the medical University of SC. I wonder though, how many of the families were meat eaters?
