One Dietary Supplement Shown to Reduce Aggression by Up to 28%

A new study highlights the impact of omega-3 supplements on aggression reduction.

Dietary Supplement Reduces Aggression by Nearly 30 Percent

A 2024 study reveals that omega-3 supplements could reduce aggression levels by up to 28 percent. This finding emerged from a meta-analysis conducted by researchers at the University of Pennsylvania, examining 29 randomized controlled trials involving 3,918 participants. The study noted a significant short-term effect across various demographics, indicating that omega-3 may aid in alleviating both reactive and proactive aggression. Neurocriminologist Adrian Raine suggested that omega-3 supplementation could be valuable in various settings, including clinics and criminal justice systems. Though more extensive research is needed, the current results support the benefits of omega-3 for mental health.

"I think the time has come to implement omega-3 supplementation to reduce aggression."

Adrian Raine emphasizes the urgency of using omega-3 in various environments.

"At the very least, parents should know that an extra portion or two of fish each week could help."

Raine suggests practical dietary changes for families dealing with aggression.

"Omega-3 is not a magic bullet that is going to completely solve the problem of violence in society."

The implications of this study extend beyond nutrition. As society grapples with rising aggression and violence, understanding dietary influences on behavior is critical.

However, experts caution against viewing omega-3 as a standalone solution to societal violence. This highlights the need for comprehensive strategies that combine diet, environment, and psychological support.
