Compelling evidence has been found by a meta-analysis of 2024 that generic omega-3 fatty acid supplements, typically fish oil, may be a major means to reduce aggression in a variety of people. This study, appearing in Aggression and Violent Behavior, further endorses the mental health benefits of these units, moving away from the usual descriptors: heart and brain health.

The analysis put together studies from 29 randomized controlled trials from the year 1996 onward, to 2024, totaling 3,918 participants. This group was diversified with respect to age, including children, adolescents, adults, and older individuals. On an average, these trials were of 16 weeks’ duration, which gave the researchers ample time to evaluate the change in behavior.

The results were noteworthy: Omega-3 supplements were effective short-term in reducing aggressiveness, with up to 28% in some cases. Important considerations, such as age, gender, and duration of supplementation, were factored into the research and still produced positive trends in the results.

The decline was observed in both reactive aggression (the sudden onset of behavior directed at a perceived threat) and proactive aggression (premeditated aggression for goal attainment).

From a biological standpoint, it has to do with the role omega-3s play in brain functioning and inflammation. Omega-3 fatty acids, especially EPA and DHA, are paramount to maintaining the structural and functional integrity of neurons. They also keep systemic inflammation at bay, which is thought to play its part in the disturbance of mood and behavior.

This makes omega-3 an excellent case candidate for being enlisted in therapeutic approaches concerned with emotional and behavioral regulation.

The neurocriminologist and contributor to the research Dr. Adrian Raine, says this finding is for consideration while giving omega-3 supplements for aggression reduction in schools, prisons, or clinical treatment programs. “Omega-3 is not a silver bullet”, he cautioned, “but the evidence does show a tangible benefit that is fairly easy to do.”

Another important caution the scientists give is that omega-3 supplements are not to be construed as a complete answer to the problems of violent behavior or serious anxiety disorders, but rather as a possible preventive or adjunctive step. Which means that because omega-3 is already known to do low harm to the body while yielding positive cardiovascular benefits, it might just offer mental well-being along with physical well-being.

As interest increases globally in non-pharmaceutical interventions in behavior science, this study reopens the question of simple diet-related interventions that can be shown to affect both public health as well as individual social outcomes.

Further studies can be commissioned for examining long-term outcomes, dosages, or other complementary interventions that synergize omega-3 with another behavioral therapy.
