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