Omega-3 fatty acids, also sometimes called n-3, have a close connection with aggression. They belong to the polyunsaturated fatty acids. They are essential for the proper functioning of our body. Essential omega-3 acids for humans include alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).

Omega-3 Fatty Acids Reduce Aggression

Scientists from the University of Pennsylvania based their findings on previous research concerning the impact of omega-3 supplementation on aggression. Their meta-analysis considered 29 randomized controlled trials, encompassing a total of 3,918 participants, ranging from children up to 16 years old to older adults aged 50 to 60. The studies were conducted between 1996 and 2024, averaging about 16 weeks in duration.
