A growing body of research suggests that nutrition may play a meaningful role in attention-deficit/hyperactivity disorder (ADD/ADHD). Studies have explored the impact of overall diet quality, avoidance of certain food additives, essential fatty acid intake, and targeted vitamin and mineral supplementation.
One study, published in Magnesium Research (2006; 19(1):46–52), examined the effects of magnesium and vitamin B6 supplementation in children diagnosed with ADHD. The study included 40 children with ADHD and 36 children who served as controls.
Children in the treatment group received magnesium at a dose of 6 mg per kilogram of body weight per day, along with vitamin B6 at 60 micrograms per kilogram of body weight per day. Supplementation continued for at least eight weeks. The children were evaluated at baseline, during the intervention, and at the end of the study.
Researchers found that supplementation was associated with improvement in ADHD symptoms. Magnesium status was assessed by measuring magnesium levels in red blood cells, which is considered a more reliable indicator of magnesium status than serum levels alone. Children with ADHD tended to have lower red-blood-cell magnesium levels at the start of the study, and these levels increased following supplementation.
Other research has also reported links between nutritional status and ADHD, suggesting that nutrient deficiencies may contribute to symptom severity in some children. While nutrition is unlikely to be the sole factor involved in ADHD, these findings support the idea that dietary assessment and nutritional support may be a valuable part of a broader, individualized approach.
