Omega-3 Supplementation Linked to 30% Reduction in Aggression, Study Finds

A 2024 meta-analysis from the University of Pennsylvania found that omega-3 supplementation reduces aggression by 30% across age groups, genders, and dosages. The study, led by criminology professor Adrian Raine and former teaching assistant Lia Brodrick, analyzed 29 studies with 3,918 participants from 19 independent laboratories between 1996 and 2024. Both reactive and proactive aggression decreased. Raine advocates implementing omega-3 in community, clinical, and criminal justice settings, though he cautions it is not a complete solution. Only one lab conducted long-term follow-up; the average observation period was 16 weeks. The researchers call for further study on long-term effects. Omega-3 also reduces risks of heart attacks and strokes.
