EPAX® (Concentrated Omega-3 Fish Oil)

Evidence Level
Strong
1 Clinical Trial
3 Documented Benefits
4/5 Evidence Score

EPAX® is a brand of concentrated, purified fish oil omega-3s (EPA and DHA) from Pelagia, used in supplements where a clinically relevant, well-characterized omega-3 dose matters. EPA and DHA are the long-chain marine omega-3s with the strongest evidence for heart, brain, and inflammatory health.

Studied Dose A serving typically providing several hundred milligrams to over a gram of combined EPA and DHA per day.
Active Compound Concentrated marine omega-3 fatty acids (EPA and DHA) from purified fish oil, in triglyceride or ethyl-ester form.

Benefits

Cardiovascular health

EPA and DHA support healthy triglyceride levels, blood vessel function, and overall cardiovascular health, the best-established benefit of marine omega-3s.

Brain and mood

DHA is a major structural fat in the brain, and omega-3 intake is studied for supporting cognition and mood across the lifespan.

Supported by Trial 1

Omega-3 status

Supplementing with concentrated EPA and DHA reliably raises the omega-3 index, a marker of long-term omega-3 sufficiency linked to health outcomes.

Supported by Trial 1

Mechanism of action

1

Membrane incorporation

EPA and DHA are built into cell membranes, improving their fluidity and serving as precursors to less-inflammatory signaling molecules.

2

Anti-inflammatory resolution

Omega-3s give rise to specialized pro-resolving mediators that help switch off inflammation, supporting heart and joint health.

Clinical trials

Omega-3 Supplementation and Omega-3 Status — Study
PubMed

Study of fish consumption and omega-3 supplementation on the omega-3 index and related outcomes. (McMullan et al. 2025, Journal of Nutrition)

Adults.

Omega-3 supplementation raised the omega-3 index, confirming that concentrated EPA and DHA reliably improve omega-3 status.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated — purified fish oil is well tolerated.
Mild fishy aftertaste, burping, or loose stools can occur; take with meals.
Choose a purified product to minimize contaminants.

Important Drug interactions

Anticoagulants and antiplatelets — high-dose omega-3 may add to bleeding risk; monitor.
Blood pressure medication — possible mild additive lowering.
Tell your doctor before high doses if you have a bleeding disorder.
