ADHD and Nutrition in Children and Teens: The State of the Science

Attention-Deficit Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental conditions in children and adolescents. As an integrative psychiatric practice, we recognize that effective care goes beyond medication management. Nutrition plays a key—though often under appreciated—role in supporting brain health, attention, focus, and emotion regulation in youth with ADHD.
But what does the current science actually say about the relationship between nutrition and ADHD? Let’s break down what we know—and what’s still emerging.
Nutritional Deficiencies and ADHD: What the Research Shows
Several studies have identified a link between nutritional deficiencies and ADHD symptoms:
• Iron: Low ferritin levels have been associated with increased hyperactivity and impulsivity. Iron is crucial for dopamine metabolism, which plays a central role in attention and executive function.
• Zinc: Zinc contributes to neurotransmitter regulation and melatonin production. Some studies suggest supplementation may improve response to some ADHD medications.
• Omega-3 Fatty Acids: Essential for brain development, EPA and DHA have been shown to modestly improve attention and behavior in children with ADHD. While the most common sources of omega fatty acids are fish and fish oils, plant-based sources include seaweed, edible algae, and seeds like flax, chia, and hemp, which contain omega-3 fatty acids that can be converted to EPA and DHA in the body.
• Magnesium: Important for neuromuscular function and neurotransmission, low magnesium has been correlated with increased irritability and inattention.
• Vitamin D: Emerging evidence links low vitamin D levels with cognitive impairment and increased ADHD symptom severity.
While supplementation may help in cases of deficiency, it’s essential to test and treat based on individualized needs rather than use a one-size-fits-all approach.
The Role of Diet Patterns
Beyond individual nutrients, overall dietary patterns appear to influence ADHD symptom patterns:
• Western Diets (high in processed foods, refined sugars, and saturated fats) have been associated with a greater prevalence of ADHD symptoms. Some studies have shown an association between artificial coloring in food and increased ADHD symptoms (particularly inattention, hyperactivity, and restlessness). A Review of the Association of Blue Food Coloring With Attention Deficit Hyperactivity Disorder Symptoms in Children showed that children who consumed artificial food coloring had statistically significant increases in ADHD symptoms over those who excluded these colorings from their diet. The UK and EU currently recommend warning labels on foods containing specific dyes.
• Mediterranean-Style Diets, which emphasize whole grains, fruits, vegetables, lean proteins, and healthy fats, are linked to better cognitive performance and fewer behavioral concerns.
Gut-Brain Connection
The gut microbiome’s influence on brain function is a rapidly growing field. Though we’re still in early stages of understanding, research suggests that imbalances in gut bacteria (also called dysbiosis) may contribute to neuroinflammation, which in turn impacts attention and mood regulation. Probiotics and prebiotics show promise but require more high-quality, long-term studies, particularly in children.
Pediatric Wellness Partners Approach to ADHD Care
We believe in a personalized, evidence-informed approach to pediatric mental health. When working with families managing ADHD, we:
• Screen for nutritional deficiencies with appropriate lab testing
• Offer targeted supplement recommendations when clinically indicated
• Provide referrals to pediatric dietitians for comprehensive dietary planning and intervention if ADHD symptoms or treatments interfere with appetite or growth
• Educate families on the role of lifestyle factors—including sleep, movement (physical activity), and food quality—in ADHD management and support patients and families through behavior change to begin using new strategies and building wellness habits that can reduce symptoms. In many cases, efforts towards improved nutrition, sleep, movement, and tech use can help reduce the dose or frequency of medication treatment.
• Review medication options and prescribe medication as appropriate.
By addressing underlying physiological needs, we support children in functioning at their best—in school, at home, and in their daily lives.
