A new study has found that "omega-3 fatty acids, available as dietary supplements in fish oil capsules, can reduce aggression." Previously, omega-3 was linked to the prevention of schizophrenia, while aggressive behavior towards society is believed to partly stem from nutritional deficiencies. Researchers at the University of Pennsylvania relied on previous studies regarding the effects of omega-3 supplements on aggression. The study included 29 randomized controlled trials with 3,918 participants. In all trials, researchers observed a modest (but significant) short-term effect, resulting in a reduction in aggression of up to 28% across various multiple variables (including age, gender, medical diagnosis, treatment duration, and dosage). The trials, which were conducted between 1996 and 2024, lasted an average of 16 weeks and covered a diverse range of demographics, from children aged 16 years or younger to older adults aged 50 to 60. The overall decrease in aggressive behavior included both reactive aggression (in response to provocation) and proactive aggression (planned behavior). Larger studies over longer periods are needed to strengthen the relationship between omega-3 and reduced aggressive behavior. Neurocriminologist Adrian Raine states, "Omega-3 is not a magic bullet that will completely solve the problem of violence in society. But can it help? Based on these results, we believe it can, and we need to start acting on the new knowledge we have."
