Fish oil pill may make 'bad' cholesterol less dangerous, study finds
NCT ID NCT04152291
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tested whether taking a high-dose fish oil supplement (E-EPA) for one month changes how LDL ('bad' cholesterol) clumps together in 68 healthy adults. Researchers measured blood fats and LDL stickiness before, during, and after the supplement period. The goal was to understand how E-EPA might lower heart disease risk.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ethyl eicosapentaenoic acid (E-EPA, also known as icosapent ethyl)
- What this could lead to
- If it works, this could help explain how E-EPA lowers heart disease risk by making LDL particles less sticky.
- What could go wrong
- This is a small, early-stage study in healthy people, not patients. Results may not apply to those with high cholesterol or heart disease.
