Omega-3 Fatty Acids May Help Reduce Anger and Aggression, Research Finds

Most people reach for omega-3 supplements to Support heart function or sharpen their focus, but a growing body of evidence suggests these powerful fatty acids may do something even more surprising: help people feel calmer and less prone to angry, aggressive reactions. For anyone looking to Support their emotional wellness from the inside out, this research offers a genuinely encouraging reason to take a closer look at what is on their supplement shelf.

According to Aggression and Violent Behavior, a comprehensive review of 29 randomized controlled trials involving nearly 4,000 participants found consistent evidence that omega-3 supplementation is linked to meaningful reductions in aggressive behavior. Across a wide range of variables including age, sex, dosage, and treatment duration, researchers observed aggression decrease by as much as 28 percent. That is a remarkable finding for a supplement most people already consider a nutrition essential.

What makes these results particularly compelling is that omega-3s appeared to reduce both impulsive, emotionally driven aggression and the more calculated, predatory kind. Neurocriminologist Adrian Raine noted that the evidence is now strong enough to consider implementing omega-3 supplementation across community, clinical, and even criminal justice settings. He pointed out that something as simple as adding a couple of fish-based servings per week could meaningfully Support a child receiving treatment for aggressive behavior, alongside any other care they are already getting.

This connection between diet and emotional regulation is not entirely new. Researchers have long noted links between nutritional gaps and higher rates of antisocial behavior, and countries with greater fish consumption have historically shown lower rates of violent behavior at the population level.

For those following a plant-based lifestyle, there is wonderful news: algae-based omega-3 supplements deliver the same EPA and DHA found in fish oil without any harm to marine wildlife. Since roughly 90 percent of Americans fall short of adequate omega-3 intake, choosing an algae-derived supplement is a compassionate and sustainable way to close that gap while supporting both your mental health and the planet.
