Long-term effect of omega-3 fatty acid supplementation in active rheumatoid arthritis. A 12-month, double-blind,
1Arthritis and Metabolic Bone Disease Research Unit, K. U. Leuven, U. Z. Pellenberg, Belgium.
Objective:
To study the long-term effects of supplementation with omega-3 fatty acids (omega 3) in patients with active rheumatoid arthritis.
Methods:
Ninety patients were enrolled in a 12-month, double-blind, randomized study comparing daily supplementations with either 2.6 gm of omega 3, or 1.3 gm of omega 3 + 3 gm of olive oil, or 6 gm of olive oil.
Results:
Significant improvement in the patient's global evaluation and in the physician's assessment of pain was observed only in those taking 2.6 gm/day of omega 3. The proportions of patients who improved and of those who were able to reduce their concomitant antirheumatic medications were significantly greater with 2.6 gm/day of omega 3.
Conclusion:
Daily supplementation with 2.6 gm of omega 3 results in significant clinical benefit and may reduce the need for concomitant antirheumatic medication.
