Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults over 18 with a diagnosis of rheumatoid arthritis for at least one year and stable disease status.
✕Probably not a fit
Patients with other rheumatologic autoimmune diseases or those consuming omega-3 supplements outside the study may not benefit.

What this trial studies
This clinical trial aims to evaluate the effectiveness of DPA-rich seal oil in alleviating symptoms associated with rheumatoid arthritis. It is a multi-center, randomized, double-blind study involving 130 participants diagnosed with rheumatoid arthritis. The study will assess various outcomes, including disease activity, quality of life, and inflammatory biomarkers, using established clinical measures and questionnaires. Participants will be randomly assigned to receive either the seal oil treatment or a control, allowing for a robust comparison of results.
Why it matters
Potential benefit: If successful, this study could provide a novel dietary intervention for managing rheumatoid arthritis symptoms.
How similar studies have gone: While this approach is novel, similar studies exploring dietary interventions for inflammatory conditions have shown promising results.
