How fish oil might stop artery gunk from causing inflammation
Eicosapentaenoic acid (EPA) inhibited lipoprotein(a) [Lp(a)] oxidation and its effects on expression of oxidative stress and pro-inflammatory proteins in endothelial cells

Surprising Findings
EPA didn’t just reduce oxidation—it completely prevented all four inflammation markers from rising, even though oxidized Lp(a) strongly triggered them.
Most antioxidants only partially reduce inflammation; here, EPA fully neutralized multiple strong signals, suggesting a broader protective mechanism than expected.
Practical Takeaways
People with high Lp(a) may consider high-dose EPA (like 4g/day icosapent ethyl) under medical supervision, especially if they’ve had heart events.

When the inner lining of your arteries gets damaged, bad cholesterol (LDL) slips in and gets oxidized, which tricks your body into sending in immune cells that create fatty buildup—leading to clogged arteries.
When scientists added EPA (a healthy omega-3 fat) to human blood vessel cells that were already stressed by a harmful cholesterol particle, the cells made a lot more of a protective protein called HO-1 — and this wasn’t just a fluke, it was a real, significant boost.
Scientists found that adding a specific amount of a fish oil component called EPA to blood proteins in a test tube cut down their damage from rust-like oxidation by more than half in just two hours.
When a harmful form of a blood fat called Lp(a) gets oxidized, it stresses the lining of blood vessels and makes them produce more protective proteins — but adding a type of omega-3 fish oil (EPA) stops this stress response.
When you add EPA (a healthy omega-3 fat) and Lp(a) (a type of cholesterol particle) together to the lining of blood vessels in a lab, it turns up a special protein called PPARγ that helps calm down inflammation.
