What side effects and interactions matter?

Omega-3 supplements can cause heartburn, nausea or diarrhea. High doses may increase bleeding problems with warfarin or other anticoagulants; a medication review is appropriate. 1

Who needs particular caution?

The BfR advises people with heart disease or cardiovascular risk factors to discuss omega-3 supplements with a clinician because higher doses can increase atrial fibrillation risk. 2

Is more necessarily better?

The BfR reiterates its precautionary recommendation of no more than 1.5 g/day combined DHA and EPA from all sources. This is not an intake target. 3
