EPA/DHA are lab-measured from each product's third-party (IFOS/NSF/iTested) report — the amount in the bottle, not the label. Retailer links are paid when tagged.
What counts as "high-EPA"?
There's no legal definition, but in practice a high-EPA fish oil (a) delivers a large EPA dose per serving and (b) has an EPA:DHA ratio above 1:1 — often ~1.5:1 or higher. People seek EPA-dominant oils because much of the omega-3 research on mood and inflammation used EPA-heavy doses. This is general information, not medical advice — talk to a clinician about your own dose.
Whatever EPA level you want, you still pay per gram of omega-3 — compare the whole field in the full ranking.

What is considered a high-EPA fish oil?
There's no official cutoff, but generally a product delivering well over ~500 mg EPA per serving with an EPA:DHA ratio above 1:1. EPA-dominant oils are what 'high-EPA' means.
