What this claim means

When omega-3 fatty acids become oxidized, they trigger inflammation and cause biological harm; non-oxidized omega-3 fatty acids do not.

See the technical phrasing

Oxidized omega-3 fatty acids induce pro-inflammatory biological effects and are associated with harmful biological outcomes, whereas non-oxidized omega-3 fatty acids do not produce these effects.

Why this might work
Verified
based on 3 studies

When omega-3 fats break down due to oxidation, they enter blood vessel cells and turn on a specific control switch called PPARα. This switch shuts down a major inflammation signal called NF-κB, which stops the cells from producing sticky molecules that attract immune cells. As a result, fewer immune cells stick to the blood vessel walls and cause swelling.
