The Claim

Oxidized eicosapentaenoic acid (EPA) reduces human neutrophil and monocyte adhesion to activated endothelial cells under static and physiological flow conditions by suppressing the surface expression of ICAM-1, VCAM-1, and E-selectin, whereas native EPA does not.

Source: Oxidized omega-3 fatty acids in fish oil inhibit leukocyte-endothelial interactions through activation of PPAR alpha.

How it works
1 study reviewed
In plain English

Oxidized EPA, but not regular EPA, directly reduces the sticking of white blood cells to blood vessel walls by lowering levels of specific adhesion molecules on the vessel surface.

See the scientific wording

Oxidized eicosapentaenoic acid (EPA), but not native EPA, reduces human neutrophil and monocyte adhesion to activated endothelial cells under both static and physiological flow conditions by suppressing the surface expression of adhesion molecules ICAM-1, VCAM-1, and E-selectin, suggesting oxidized omega-3 fatty acids may directly modulate vascular inflammation.

Why this might work

When EPA is oxidized, it enters endothelial cells and turns on a protein called PPARα, which blocks another protein called NF-κB from activating genes that make sticky molecules on the blood vessel surface. Without these sticky molecules, white blood cells cannot attach to the vessel wall, reducing inflammation.

What the research says

1 study
  1. Study: Oxidized omega-3 fatty acids in fish oil inhibit leukocyte-endothelial interactions through activation of PPAR alpha.

    The study directly measured leukocyte adhesion to endothelial cells under controlled conditions and found oxidized EPA, but not native EPA, significantly reduced adhesion and adhesion molecule expression. This provides descriptive evidence of a differential effect based on oxidation state.
