Omega-3 fatty acids

Widely discussed for ADHD and mood; effects in studies are small and inconsistent.

How it works

Omega-3s (EPA, DHA) are structural fats in brain cell membranes, found in fish and supplements.

What the evidence says, use by use

Evidence is specific to the condition, population and—for devices—the exact product. One label never covers everything.

ADHD: Reducing ADHD symptoms

Emerging / limited
Who was studied / who it’s for: Children with ADHDWhat this label means: Early, small or mixed studies. Interesting, but not equivalent to established care.

Studies show small, inconsistent effects at best; omega-3s are not a substitute for established ADHD treatment.

Cautions & things to know

Questions for a clinician

Conversation prompts, not a treatment plan.

  • Is there any reason to think diet is low in omega-3s?
  • What would we measure to know if it helps?

Educational, not medical advice. NeuroCoach is an educational and care-navigation resource, not a medical provider. Information about medications, supplements, therapies, devices, clinical trials and community experiences is provided for education and exploration and is not a recommendation, diagnosis or treatment plan. Evidence varies substantially among interventions. Decisions about medical or mental-health treatment should be made with an appropriately qualified healthcare professional. Do not start, stop or change medication, supplements or treatment based solely on information found here.
