Supplements Benefit Children with ADHD... According to research in the Journal of the American College of Nutrition (2004, vol.23: 545s-548s), children suffering from attention deficit-hyperactivity disorder (ADHD) may benefit from supplements of magnesium and vitamin B6. ADHD is characterized by inattention, hyperactivity, and impulsivity and usually appears during preschool and early school years.

 Magnesium deficiency has previously been reported in children with ADHD and supplementing with the mineral has been shown to decrease hyperactivity. This study examined 52 children with ADHD under age 15. Though exact dosages were not clear in the study abstract, the children appeared to receive a combination of six milligrams per kilogram of body weight per day of magnesium and 0.8 milligrams per kilogram of body weight per day of vitamin B6 for a period of one to six months. By the end of the study, significant improvements were seen among all participants in hyper-excitability symptoms.
