This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.

What is this trial?

This study is testing a multinutrient supplement (a combination of vitamins and minerals taken as pills) in children ages 6-17 who have ADHD and trouble managing their emotions or irritability. Researchers want to see if this treatment helps these symptoms, and they're also testing new, easier ways to collect information from families during the study—like tracking your child's behavior on your phone and collecting blood and urine samples at home instead of in a clinic.

Many children with ADHD also struggle with emotional regulation, and current treatments don't work for everyone. This study is exploring whether nutritional support might help fill that gap, while also making research participation easier and more accessible for Black and Hispanic families.

Do you qualify?

You likely qualify if…

your child is between 6 and 17 years old
your child has ADHD symptoms or has been suspected of having ADHD based on parent observation
your child also experiences irritability or mood problems
your child can swallow up to 8 pills a day
your child has not taken ADHD medication for at least 2 weeks before starting the study
you identify as Black, Hispanic, Latino/a, or more than one race

You likely don't qualify if…

your child has a neurological disorder or serious medical condition like cancer, kidney disease, liver disease, diabetes, or thyroid problems
your child has a psychiatric condition that required hospitalization
your child is allergic to any vitamin or mineral supplement ingredients
your child is of reproductive age and sexually active or pregnant
your child has a mineral metabolism disorder

What participation looks like

You and your child will participate in an 8-week study. Your child will take the multinutrient supplement daily (up to 8 pills per day), and you'll track their target behavior problem using a simple app on your phone throughout the day. At home, you'll also collect two small blood samples using an easy finger-prick device and urine samples on filter cards at specific times. The study is designed to fit into your family's routine rather than requiring many clinic visits.
