A meta-analysis published in the journal Aggression and Violent Behavior examined 29 randomized controlled trials and found that omega-3 fatty acid supplements reduced aggressive behavior by an average of 27% across both children and adults. The analysis measured two distinct forms of aggression: reactive aggression, which is an impulsive response to provocation, and proactive aggression, which involves planned acts to gain dominance.
The 27% reduction in both types of aggression occurred consistently regardless of age, gender, or baseline aggression levels. According to Dr. Adrian Raine of the University of Pennsylvania, the lead researcher, “The results are modest but statistically significant, suggesting omega-3s may be a viable adjunct therapy.” An earlier analysis had reported a similar 30% reduction, further supporting the trend. Researchers note that while the effect is moderate, it could have meaningful implications at a population level given the widespread prevalence of aggressive behaviors.
Omega-3 fatty acids, particularly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), influence brain function through distinct mechanisms. DHA is a major structural component of brain cells and supports neuroprotection, while EPA influences neurotransmitter systems including serotonin and dopamine, which are critical for mood regulation. Low intake of omega-3s is associated with increased inflammation, an impaired stress response, and higher likelihood of depression. The meta-analysis notes that nearly 90% of Americans do not meet the recommended daily intake of 500 milligrams of omega-3s. Dietary sources include fatty fish such as salmon, mackerel, and sardines, while supplements can provide therapeutic doses ranging from 1,000 to 4,000 milligrams per day. Researchers emphasized that increasing omega-3 intake “will not eliminate feelings of aggression but can have meaningful impact alongside other therapies.”
