When scientists added a specific amount of omega-3 fish oil (EPA) to human blood vessel cells in a dish, the cells soaked up a lot more EPA and ended up with way more of it compared to the bad fats, which is a good sign the cells are using it properly.

Omega-3 and omega-6 fatty acids have distinct effects on endothelial fatty acid content and nitric oxide bioavailability

Cross-Sectional Study

In Vitro

2021 Oct

Scientists gave endothelial cells a specific type of omega-3 fat (EPA) and found that the cells absorbed it really well — their EPA levels went up 10 times, and the balance between EPA and another fat (AA) also improved 10 times, just like the claim said.

Similar Assertions

When scientists added a type of omega-3 fatty acid called EPA to blood vessel cells in a dish, the cells made more of a helpful molecule (nitric oxide) and less of a harmful one (peroxynitrite), which might help keep blood vessels healthier and less inflamed.

When you add a specific fat called arachidonic acid to blood vessel cells in a lab, it pushes out another healthy fat called EPA, making EPA much less common in the cell membranes—like a crowded room where one person pushes others out.
