SupplementDEX

Attention deficit hyperactivity disorder (ADHD)

Supplements studied for attention deficit hyperactivity disorder (ADHD).

Overview

SupplementDEX indexes 21 supplements for attention deficit hyperactivity disorder (ADHD) across 56 studies.

Zinc (DEX Score 72; medium effect size, high evidence, very high trust) may slightly reduce ADHD symptoms in children, especially alongside stimulant medicines and when zinc levels are low. Magnesium (DEX Score 72; medium effect size, high evidence, very high trust) evidence is unclear: one study in magnesium-deficient children reported improved hyperactivity, while magnesium plus vitamin D in others without deficiency showed minimal benefit.

L-Carnitine (DEX Score 64; medium effect size, medium evidence, high trust) has insufficient evidence per available summaries. Caffeine (DEX Score 40; very low effect size, high evidence, medium trust) does not reduce ADHD symptoms in children, and Ginkgo (DEX Score 40; very low effect size, high evidence, medium trust) underperformed methylphenidate in one trial.
