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.
