It is relatively well known that omega-3 and 6 fatty acids can play a role in the management of attention deficit hyperactivity disorder, aka ADHD.
Now, new evidence has revealed that iron as a nutrient may also have a role in the development of ADHD. Iron is a valuable trace element that plays a role in brain function and dopamine systems. We have also seen from studies with teenagers that iron supplements may help to aid ‘class concentration’. So, from these perspectives such a link makes potential sense.
The scientific paper pooled results from 11 studies. Findings showed that serum ferritin levels (a marker of iron stores) were lower in ADHD cases. These results do suggest that children with ADHD may have lower stores of iron but other studies are needed to reconfirm findings.
These are intriguing results showing that serum ferritin levels are lower in children with ADHD. Whether this is a consequence or cause of ADHD is yet to be determined. That said, iron status should certainly be considered in future studies looking at ADHD in children.
