Omega-3 Polyunsaturated Fatty Acids for Core Symptoms of Attention-Deficit/Hyperactivity Disorder: A Meta-Analysis of Randomized Controlled Trials.

Conclusions: Our findings indicate that omega-3 PUFAs did not improve ADHD core symptoms, but long-term supplementation may have potential benefits. The main limitation of the study was the moderate heterogeneity and small sample sizes in subgroup analyses and the lack of dietary pattern information.
