Abstract: A brand new examine discovered that omega-3 supplementation can scale back aggression by 30%. The examine reviewed 29 randomized managed trials, displaying short-term advantages throughout numerous demographics. Researchers advocate for utilizing omega-3 dietary supplements as a complementary therapy for aggressive conduct.
Key Details:
- Aggression Discount: Omega-3 supplementation can scale back aggression by 30%.
- Examine Scope: Meta-analysis included 29 trials with 3,918 members.
- Broader Advantages: Omega-3 can be useful for coronary heart well being and is protected to make use of.

Individuals who recurrently eat fish or take fish oil dietary supplements are getting omega-3 fatty acids, which play a essential position in mind operate. Analysis has lengthy proven a foundation within the mind for aggressive and violent conduct, and that poor diet is a danger issue for conduct issues.
Penn neurocriminologist Adrian Raine has for years been finding out whether or not omega-3 supplementation may due to this fact scale back aggressive conduct, publishing 5 randomized managed trials from totally different nations.
He discovered important results however wished to know whether or not these findings prolonged past his laboratory.
Now, Raine has discovered additional proof for the efficacy of omega-3 supplementation by conducting a meta-analysis of 29 randomized managed trials. It reveals modest short-term results—he estimates this intervention interprets to a 30% discount in aggression—throughout age, gender, analysis, therapy length, and dosage.
Raine is the lead creator of a brand new paper printed within the journal Aggressive and Violent Habits, with Lia Brodrick of the Perelman College of Drugs.
“I believe the time has come to implement omega-3 supplementation to scale back aggression, no matter whether or not the setting is the group, the clinic, or the legal justice system,” Raine says.
“Omega-3 just isn’t a magic bullet that’s going to fully resolve the issue of violence in society. However can it assist? Primarily based on these findings, we firmly consider it could, and we must always begin to act on the brand new data now we have.”
He notes that omega-3 additionally has advantages for treating coronary heart illness and hypertension, and it’s cheap and protected to make use of.
“On the very least, dad and mom in search of therapy for an aggressive youngster ought to know that along with every other therapy that their youngster receives, an additional portion or two of fish every week may additionally assist,” Raine says.
This meta-analysis reveals that omega-3 decreased each reactive aggression, which is conduct in response to a provocation, and proactive aggression, which is deliberate.
The examine included 35 impartial samples from 29 research performed in 19 impartial laboratories from 1996 to 2024 with 3,918 members. It discovered statistically important results whether or not averaging impact sizes by examine, impartial pattern, or by laboratory.
Solely one of many 19 labs adopted up with participations after supplementation ended, so the evaluation centered on adjustments in aggression from starting to finish of therapy for experimental and management teams, a interval averaging 16 weeks.
“Whereas there’s worth in understanding whether or not omega-3 reduces aggression within the short-term,” the paper states, “the following step will probably be to judge whether or not omega-3 can scale back aggression within the long-term.”
The paper notes a number of different attainable avenues for future analysis, akin to figuring out whether or not mind imaging reveals that omega-3 supplementation enhances prefrontal functioning, whether or not genetic variation impacts the result of omega-3 therapy, and whether or not self-reported measures of aggression present stronger proof for efficacy than observer studies.
“On the very least, we’d argue that omega-3 supplementation ought to be thought of as an adjunct to different interventions, whether or not they be psychological (eg CBT) or pharmacological (eg risperidone) in nature, and that caregivers are knowledgeable of the potential advantages of omega-3 supplementation,” the authors write.
They conclude, “We consider the time has come each to execute omega-3 supplementation in observe and in addition to proceed scientifically investigating its longer-term efficacy.”

Summary
Omega-3 supplementation reduces aggressive conduct: A meta-analytic evaluation of randomized managed trials
There may be growing curiosity in the usage of omega-3 dietary supplements to scale back aggressive conduct.
This meta-analysis summarizes findings from 29 RCTs (randomized managed trials) on omega-3 supplementation to scale back aggression, yielding 35 impartial samples with a complete of 3918 members.
Three analyses had been performed the place the unit of research was impartial samples, impartial research, and impartial laboratories. Important impact sizes had been noticed for all three analyses (g = 0.16, 0.20, 0.28 respectively), averaging 0.22, within the course of omega-3 supplementation lowering aggression.
There was no proof of publication bias, and sensitivity analyses confirmed findings. Moderator analyses had been largely non-significant, indicating that useful results are obtained throughout age, gender, recruitment pattern, diagnoses, therapy length, and dosage.
Omega-3 additionally decreased each reactive and proactive types of aggression, significantly with respect to self-reports (g = 0.27 and 0.20 respectively).
It’s concluded that there’s now enough proof to start to implement omega-3 supplementation to scale back aggression in kids and adults – no matter whether or not the setting is the group, the clinic, or the legal justice system.
