SUPPLEMENTS & NUTRITION

Zinc & magnesium

Useful when someone is deficient; evidence for ADHD symptoms is limited.

NeuroCoach · Evidence explorerSources checked October 5, 2026Editorial draft · clinical review pending

How it works

Both minerals are involved in many enzyme and nerve functions; deficiency can occur with restricted diets.

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.

Across conditions: Treating documented deficiency

Established
Who was studied / who it’s for: People with a measured or likely deficiencyWhat this label means: Strong research and/or authoritative clinical guidelines support this specific use.

Correcting deficiency is standard care.

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 are small and inconsistent; not established as ADHD treatment.

Who usually provides it

Discuss with a clinician or pharmacist.

Cautions & things to know

  • High doses cause side effects and can interfere with other minerals and medicines.

Questions for a clinician

Conversation prompts, not a treatment plan.

  • Is there a reason to suspect deficiency (diet, selective eating)?

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.
