The Claim

Oxidized eicosapentaenoic acid (EPA) reduces leukocyte rolling and adhesion to inflamed venular endothelium in vivo in mice by approximately 75% compared to vehicle control, and this effect is not observed with native EPA.

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

Supports is higher

Support is ahead, but a single strong opposing study can change this.

How it works
1 study reviewed
In plain English

In mice with inflamed blood vessels, oxidized EPA decreases the sticking of white blood cells to vessel walls by about 75% compared to a control substance, while unmodified EPA does not produce this effect.

See the scientific wording

Oxidized eicosapentaenoic acid (EPA) reduces leukocyte rolling and adhesion to inflamed venular endothelium in vivo in mice by approximately 75% compared to vehicle control, an effect not observed with native EPA.

Why this might work

When EPA is oxidized, it enters blood vessel lining cells and turns on a specific control switch called PPARα. This switch shuts down the production of sticky proteins on the vessel wall that normally grab white blood cells. Without these sticky proteins, white blood cells cannot slow down or stick to the vessel wall, so they keep flowing past instead of gathering at the site of inflammation.

    In mice with inflamed blood vessels, a changed form of EPA from fish oil stops white blood cells from sticking to vessel walls—cutting it by about 75%—but regular EPA doesn’t do anything. This helps explain why fish oil might reduce inflammation.
