The Study
Omega-3 fatty acids have little or no cardiovascular protection: An interventional study
This study gave some people omega-3 pills and others statins to see which one helped their heart numbers better. It found they were about the same — but it didn’t compare omega-3 to nothing at all. So we can’t say omega-3 does nothing, just that it didn’t do better than the medicine they were already taking.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Even though fish oil changed blood fats similarly to the drug, it didn't actually lower the chance of heart disease events.
- 2Fish oil lowered cholesterol and triglycerides about as much as the drug, but didn't reduce heart attacks or other heart problems.

Taking fish oil supplements every day might lower your chances of having a heart attack, but it won't make a big difference in preventing other serious heart problems or getting cancer if you're a healthy older adult.
Taking fish oil supplements with EPA and DHA every day for six months might change your cholesterol levels about the same as taking a low dose of a common heart medication called atorvastatin—but it doesn’t do a better job at protecting your heart.
