Short answer

Take it with a meal that has fat for better absorption. Time of day doesn't matter; taking it daily does.

Full Protocol

Timing
Take it with a meal that has fat for better absorption. Time of day doesn't matter; taking it daily does.
Dosage
1-3g combined EPA/DHA daily. 1.5-3g EPA for brain health (Andrew Huberman). High-EPA fish oil targeting a 12% omega-3 index (Peter Attia). ~2g EPA/DHA (Rhonda Patrick). For high-risk heart patients: 4g pure EPA, prescription strength, as in REDUCE-IT.
Form
Triglyceride-form fish oil for general use. Krill oil or salmon roe deliver DHA to the brain better, because phospholipid-bound DHA crosses via the MFSD2A transporter. Algal oil is a vegan source of EPA/DHA. Avoid ethyl ester forms, which absorb less well than triglyceride or phospholipid forms.
Notes
Test your omega-3 index and target 8-12% of red blood cell membranes (Bill Harris, on The Drive). Plant ALA (flax, walnuts, chia) converts poorly to EPA/DHA, so don't rely on it. High omega-6 intake competes with omega-3s. Responses to supplements vary a lot, and testing is the only way to confirm your level.
