Grade B / moderate: probably helps, and new studies are unlikely to reverse this — but could shrink the effect size.
Who it works for
Best-studied in adults. Recorded studied dose: 1–3 g/day.

What dose was used in studies of Omega-3 for inflammation?
The recorded studied dose for Omega-3 and inflammation is 1–3 g/day. This is a source detail, not a dose recommendation.
Does Omega-3 work for inflammation if I'm not deficient?
The recorded studied population is adults. This field alone does not show whether deficiency or baseline status changes the effect.
Omega-3 or the next-best alternative for inflammation?
See the compare block above for the head-to-head with the most-cited alternative. Grade + certainty differences matter more than any single trial.
