Quick Answer

Most experts recommend 1-3g of EPA specifically per day. Huberman targets 1.5-3g EPA for mood and brain health. Attia aims for a 12% omega-3 index using high-EPA fish oil. Patrick recommends about 2g daily of combined EPA and DHA. Test your omega-3 index and target 8-12%.

What Researchers Say

Andrew Huberman
Andrew Huberman Strongly Agrees

Recommends 1.5-3g EPA daily for brain health, mood, and depression management.

Peter Attia
Peter Attia Strongly Agrees

Targets 12% omega-3 index with high-EPA fish oil. Discusses high-dose EPA (4g/day) for cardiovascular risk reduction.

Rhonda Patrick
Rhonda Patrick Strongly Agrees

Recommends about 2g daily. Emphasizes omega-3 index testing as a mortality and cardiovascular risk marker.

Bryan Johnson
Bryan Johnson Agrees

Includes omega-3s in Blueprint protocol. Obtains them primarily through food — flax, walnuts, and Nutty Pudding.

Mark Hyman
Mark Hyman Strongly Agrees

Considers omega-3 fats one of the four core pillars of a healthy diet. Recommends supplementation for nearly every patient.

Detailed Answer

Omega-3 dosing depends on your goal. The experts converge on 1-3g of EPA per day as the therapeutic range, but the specific amount varies by purpose.

For mood and brain health, Huberman recommends 1.5-3g of EPA (specifically EPA, not total omega-3) daily. He cites research showing EPA's role in managing depression, enhancing focus, and supporting cognitive function.

For cardiovascular health, Attia targets a 12% omega-3 index and adjusts his dose accordingly. The REDUCE-IT trial used 4g of pure EPA and showed significant cardiovascular risk reduction in high-risk patients.

Patrick recommends approximately 2g of combined EPA and DHA daily. She emphasizes testing your omega-3 index rather than guessing — target 8-12%.

The key nuance: plant-based ALA from flax and walnuts converts to EPA/DHA at only 5-10% efficiency. Marine sources (fish oil, krill oil, algal oil) are strongly preferred by 4 of 5 experts.

Related Questions

Is there such a thing as too much omega-3?

At very high doses (over 3g/day), there is a theoretical bleeding risk. The REDUCE-IT trial at 4g/day showed increased atrial fibrillation risk. Prescription-strength doses require medical supervision.

What is a good omega-3 index?

Both Patrick and Attia recommend targeting 8-12% on an omega-3 index blood test. Below 4% is considered high-risk.
