Omega-3 Fatty Acids Linked to Reduced Aggression, Study Finds
Omega-3 fatty acids have long been touted for their numerous health benefits, and a recent study has added another feather to their cap – reducing aggression. The findings of a 2024 study suggest that omega-3 supplements, commonly available in the form of fish oil capsules, could play a role in curbing aggressive behavior.
Prior research has already established a connection between omega-3 and mental health, with the fatty acids being linked to preventing conditions like schizophrenia. Aggression and antisocial behavior, on the other hand, are believed to be influenced by nutritional deficiencies. This new study delves deeper into the impact of omega-3 supplementation on aggression levels.
Conducted by researchers from the University of Pennsylvania, the study analyzed data from 29 randomized controlled trials involving nearly 4,000 participants. The results showed a modest yet significant reduction in aggression levels, with a potential decrease of up to 28% across various parameters such as age, gender, medical diagnosis, and treatment duration.

Neurocriminologist Adrian Raine, one of the lead researchers, emphasized the significance of these findings, suggesting that omega-3 supplementation could be a valuable intervention to reduce aggression in various settings.
The study encompassed a wide range of demographics, from children under 16 to individuals between 50 and 60 years old. It also noted a reduction in both reactive and proactive aggression, hinting at the broad impact of omega-3 on aggressive behavior.
While more extensive and long-term studies are needed to solidify these findings, the research underscores the potential benefits of incorporating omega-3 into one’s diet for improved brain health and behavior regulation.

The researchers point to omega-3’s anti-inflammatory properties and its role in maintaining essential brain functions as potential mechanisms behind its impact on aggression. While there are still unanswered questions, the study advocates for further exploration of omega-3’s therapeutic potential.
Moreover, the study aligns with existing research showcasing the cardiovascular benefits of omega-3, indicating a holistic advantage to incorporating this nutrient into one’s daily regimen.
As we continue to unravel the mysteries of omega-3 and its multifaceted benefits, it’s becoming increasingly clear that this essential fatty acid holds promise in promoting overall well-being and mental health.

“Omega-3 is not a panacea for societal violence,” Raine cautions. “But the evidence suggests its potential in mitigating aggression, urging us to act upon this newfound knowledge.”
