Frequently asked
How long does Omega-3 take to work for inflammation?
Trials of Omega-3 for inflammation typically report effects within 2–4 weeks, though individual response varies. Studies rarely find benefit inside 1 week for chronic outcomes.
What dose was used in studies of Omega-3 for inflammation?
Studied doses for Omega-3 in inflammation trials cluster around 1–3 g/day. See the dose block for the specific range and how it varies by form.
Does Omega-3 work for inflammation if I'm not deficient?
The effect concentrates in adults. If your baseline is normal, expect a smaller effect than the trial averages.
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.
