Universal
consensus
1-3g combined EPA/DHA daily. Huberman: 1.5-3g EPA for brain health. Attia: high-EPA fish oil targeting 12% omega-3 index. Patrick: ~2g EPA/DHA. For cardiovascular risk reduction in high-risk patients: 4g pure EPA (prescription-strength, per REDUCE-IT trial).
Full expert breakdown: How much omega-3 should you take per day?
Consensus Protocol
Dosage
- 1-3g combined EPA/DHA daily
- Huberman: 1
- 5-3g EPA for brain health
- Attia: high-EPA fish oil targeting 12% omega-3 index
- Patrick: ~2g EPA/DHA
- For cardiovascular risk reduction in high-risk patients: 4g pure EPA (prescription-strength, per REDUCE-IT trial)
Form
- Triglyceride-form fish oil for general supplementation
- Krill oil or salmon roe for superior brain DHA delivery (phospholipid-bound DHA crosses the blood-brain barrier more effectively via MFSD2A transporter)
- Algal oil as a vegan alternative for EPA/DHA
- Avoid ethyl ester forms — lower bioavailability than triglyceride or phospholipid forms
Timing
- Take with a fat-containing meal to improve absorption
- No specific time-of-day requirement
- Consistency matters more than timing
Notes
- Test your omega-3 index — target 8-12% of red blood cell membranes (Attia, Patrick, Dr
- Bill Harris)
- Plant-based ALA (flax, walnuts, chia) converts very inefficiently to EPA/DHA — do not rely on these as primary omega-3 sources
- High omega-6 intake competes with omega-3 conversion
- Individual responses to supplementation vary significantly — testing is the only way to confirm adequate levels
Expert Positions
What Each Expert Says
Huberman recommends omega-3 supplementation across multiple episodes covering brain health, depression, ADHD, headaches, aggression, and fitness. His dosage recommendations center on EPA specifically: 1.5-3g/day for brain nutrients, 1000-2000mg EPA for depression management, and 1g+ EPA for headache reduction. He discusses omega-3's role in supporting neuron membrane integrity, neurotransmitter function, mood regulation, cognitive function, and self-regulation. On the Huberman Lab Essentials episode with Dr. Rhonda Patrick, omega-3 dosage of around 2 grams and the omega-3 index as a mortality marker are discussed.
