Can certain vitamins help kids with ADHD? There have been a number of studies that show nutrition, avoidance of food additives, essential fatty acids and vitamin supplementation can all be of value for children with ADD or ADHD. A study appearing in Magnesium Research (2006; 19(1): 46-52) looked at children with ADHD and their response to supplementation with magnesium and vitamin B6. Forty children with ADHD and 36 other children, who acted as controls, participated in the study. The children were given magnesium (six mg. for every kg. of body weight per day) and vitamin B6 (60 mcg. for every kg. of body weight per day) for at least eight weeks. They were evaluated at the beginning of the study, during the study and at the end of the study. It was found that the supplementation improved the symptoms of ADHD. Magnesium levels were assessed by measuring the amount of magnesium in the red blood cells. Children with ADHD tended to have lower magnesium levels in the red blood cells. The magnesium levels increased after supplementation. Other research has shown a strong connection between nutrition and ADHD
