One Dietary Supplement Was Found to Reduce Aggression by Up to 28%

A 2024 meta-analysis published in Aggression and Violent Behavior found that omega-3 dietary supplements, commonly found in fish oil, can reduce aggression by up to 28%. The study, which included 29 randomized controlled trials with 3,918 participants, suggests that omega-3 could be beneficial for reducing both reactive and proactive aggression. While larger studies are needed to confirm these findings, the researchers believe it's time to consider omega-3 supplementation in various settings to help manage aggression.
