What it is

The other long-chain omega-3 fat from oily fish, and the one most directly involved in damping inflammation.

Why it matters

It competes with arachidonic acid for the same enzymes, which is the whole reason the AA/EPA ratio is reported.

Reading the number

It is the most supplement-responsive value on the panel and also the fastest to fall away when you stop, so record whether you were supplementing. Absolute concentration and percentage-of-total are different numbers.
