Short answer

With a meal that contains fat, for best absorption. The time of day does not matter. The fat in your meal helps emulsify the fish oil and improves the absorption of both EPA and DHA.

Detailed Answer

Omega-3 fish oil absorbs better when taken with a meal containing fat. Beyond that, the hour does not matter. Rhonda Patrick, on her own show, notes that omega-3 absorption climbs when you take it with dietary fat.

Form matters more than timing

Peter Attia takes fish oil with meals and picks the triglyceride form over the ethyl ester form, because it absorbs better. Patrick adds a wrinkle about getting DHA into the brain. Krill oil and salmon roe carry DHA in phospholipid form, which the brain's MFSD2A transporter takes up more efficiently than standard fish oil.

In practice

Take it at breakfast or dinner, whichever meal has the fat. For higher amounts (2g+ EPA/DHA), split the dose across two meals to cut any fishy aftertaste.

Related Questions

Can you take fish oil on an empty stomach?
You can, but absorption drops. Take it with a meal that has fat in it.
Does fish oil go bad?
Yes, it can go rancid. Oxidized fish oil hasn't shown clear clinical harm, but keep it refrigerated and check for off smells. Good fish oil should have little odor.
