The Study
Omega-3 Supplementation Lowers Inflammation and Anxiety in Medical Students: A Randomized Controlled Trial
This study gave some students fish oil pills and others fake pills to see if the fish oil changed how their bodies reacted to stress and how anxious they felt. It found that the fish oil group felt a little less anxious and had a little less inflammation in their blood — but only in this small group of medical students. We can't say it will work the same for everyone.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — even people with healthy diets and low inflammation saw real benefits in anxiety and immune response, suggesting omega-3s may help emotional health beyond just treating illness.
- 2Students who took fish oil had 14% less inflammation in their immune cells and 20% less anxiety.
- 3Their depression didn't change.
- 4The better their omega-6 to omega-3 balance, the better their results.
