ADHD Nutrition

Nutrition can support focus, energy, and mood for people with ADHD. I’m Amy Archer, a registered dietitian nutritionist who has worked with ADHD clients in my private practice since 2014 and at an adult ADHD clinic in Los Altos, California, from 2018 to 2024. I also wrote An Integrative & Functional Nutrition Approach to ADHD Management: Guidance for the Clinician, a guide written for health professionals (2nd Edition publishing soon).

My nutrition recommendations work alongside the care you receive from your healthcare team.

How Nutrition and Lifestyle May Support ADHD 

Nutrition can help support ADHD symptoms alongside medical care. Research has linked ADHD symptoms to low iron, vitamin D, omega-3 intake, and magnesium. Irregular meals and blood sugar swings are common, especially when medication decreases appetite. A dietitian can review your labs, eating habits, and lifestyle to identify areas of improvement.

Frequently Asked Questions

How can nutrition help with ADHD symptoms?

  • Steady blood sugar: Protein, fiber, and fat at each meal can help reduce blood sugar swings.
  • Regular meals: Plan easy meals and snacks timed around your medication schedule.
  • Food sensitivities: For some people, certain foods may worsen symptoms. The MRT test and the LEAP Protocol can help identify trigger foods and guide a personalized eating plan.

What supplements can be beneficial for people with ADHD?

  • Omega-3 intake: The SMASH fish (salmon, mackerel, anchovies, sardines, and herring), walnuts, and flax are good sources of omega-3s. Supplements may be beneficial if your healthcare team recommends them.

Why is gut health a factor in brain health and ADHD symptom management?

  • Gut health: Supporting gut health matters because the gut-brain connection can affect mood, focus, and energy.

What lifestyle factors improve brain health?

  • Exercise: Exercise increases BDNF (brain-derived neurotrophic factor), which supports cognition and brain plasticity.
