The Claim

Oxidized eicosapentaenoic acid (EPA) inhibits the expression of ICAM-1, VCAM-1, and E-selectin in endothelial cells exposed to inflammatory stimuli, whereas native EPA does not significantly alter their expression.

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

When eicosapentaenoic acid (EPA) becomes oxidized, it reduces the production of specific adhesion molecules on blood vessel lining cells during inflammation; unoxidized EPA does not produce this reduction.

See the scientific wording

Oxidized eicosapentaenoic acid (EPA) inhibits endothelial expression of ICAM-1, VCAM-1, and E-selectin in response to inflammatory stimuli, while native EPA has no significant effect, suggesting oxidation enhances the anti-inflammatory potency of omega-3 fatty acids.

Why this might work

When EPA becomes oxidized, it enters blood vessel cells and turns on a specific control switch called PPARα. This switch shuts down a different signal that would normally tell the cells to make sticky proteins that grab white blood cells. Without those sticky proteins, white blood cells cannot attach to the vessel walls, reducing inflammation.

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

    When omega-3s from fish oil get oxidized (like when they’re a little old or processed), they become much better at calming down blood vessel inflammation and stopping white blood cells from sticking around. Regular, unoxidized omega-3s don’t do this as well.
