Study summary

The purpose of this study is to investigate the use of a natural health product, as compared to placebo (an inactive substance), in managing the symptoms of ADHD. The natural health product contains the nutrients zinc, magnesium, vitamin B6 and vitamin C. Each of these nutrients has some evidence to suggest that children with ADHD might be lacking them. As such, children with ADHD might benefit from supplementing their diets with these nutrients, especially ADHD children who have below average levels.

This study will measure whether the severity of ADHD symptoms is greater in children with low levels of zinc, magnesium, and vitamin B6, and whether the severity of ADHD symptoms will decrease with supplementation of these nutrients. This study will also monitor for any adverse reactions or side effects from taking these nutrients in children.

Although these natural health products are commercially available, the use of them as a supplement or placebo in this study has been approved for use in this study by the Natural Health Products Directorate of Health Canada.

Read the detailed description

The study is a randomized control, double blinded trial. A population of 30 children diagnosed with ADHD (n=30) will be randomly assigned to the NHP group (n=15) or a placebo group (n=15). The NHP group will be provided with a weight-based dose of a chewable natural health product containing zinc, magnesium, vitamin B6 and vitamin C for 10 weeks, with an additional follow-up post intervention at 20 weeks. The placebo group will be administered a chewable placebo tablet and will follow the same regimen. Severity of ADHD symptoms will be measured at baseline, week 5 and week 10 using the Connor-3 Parent and SNAP-IV validated questionnaires. Nutritional status will be monitored at baseline and week 10 for changes in serum zinc and erythrocyte magnesium. Children will be monitored for any adverse reactions that may occur using the investigational product.Following the informed consent process, participants will undergo a structured psychiatric interview prior to enrollment and will have 4 30 minute study visits and 2 10 minute telephone calls throughout the study. Blood samples will be taken 2 times with the use of a topical anesthetic to decrease sensation during the blood draw. Once enrolled, children can withdraw from the study at any time if assent to participate is withdrawn.
