The question behind the headline
Children and adolescents with ADHD; PUFA supplements versus placebo, including omega-3 and some mixed formulations.

A 2026 baseline-status analysis was preliminary. Low blood levels do not by themselves prove that supplementation improves symptoms.

Three questions to take forward
- Was the study population similar to the person or situation I have in mind?
- Did it measure an outcome people feel or experience, or only a laboratory marker?
- How do formulation, usual care, absolute benefit and adverse effects change the interpretation?
