Is this trial a fit for you?

Likely a good fit

Children and adolescents with a DSM-5 diagnosis of ADHD, documented low omega-3 levels, stable ADHD treatment for at least 4 weeks, and SNAP-IV scores meeting the entry thresholds are ideal candidates.

Probably not a fit

Those with IQ below 80, allergy to omega-3, significant medical disorders (e.g., thyroid cancer), or major psychiatric comorbidities are excluded and unlikely to benefit from this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a 12-week randomized, placebo-controlled trial enrolling children and adolescents diagnosed with ADHD who also have omega-3 deficiency. Participants who have had no changes in ADHD treatment for at least 4 weeks are randomized to receive EPA, DHA, or a placebo. Symptom thresholds for enrollment use the SNAP-IV inattentive and hyperactive subscales, and outcomes will compare ADHD symptoms between active and placebo groups over 12 weeks. The trial is conducted at China Medical University Hospital with standard safety exclusions for medical and major psychiatric comorbidities.

Why it matters

Potential benefit: If successful, omega-3 supplementation could offer a low-risk option to reduce ADHD symptoms in youth with documented omega-3 deficiency.

How similar studies have gone: Previous trials of omega-3 supplements for pediatric ADHD have shown mixed but modest benefits, so this approach has some supportive but inconsistent evidence.
