Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Docosahexaenoic acid (DHA) is an omega-3 fatty acid found in fish oil and certain algae. Its use in supporting or treating Rheumatoid Arthritis (RA) is primarily justified by scientific investigation, not tradition. Several studies have explored the anti-inflammatory effects of omega-3 fatty acids, including both DHA and eicosapentaenoic acid (EPA), in autoimmune conditions such as RA.
Clinical trials have shown that supplementation with omega-3s can reduce joint pain and stiffness in RA patients, decrease the need for non-steroidal anti-inflammatory drugs (NSAIDs), and lower biomarkers of inflammation. However, most research uses combinations of DHA and EPA, and it is sometimes difficult to attribute benefits solely to DHA. A 2017 systematic review and meta-analysis (Gioxari et al., 2018, Nutrition) found moderate evidence that omega-3 supplementation can reduce disease activity in RA. The mechanisms are believed to involve a decrease in pro-inflammatory cytokine production and modulation of immune cell function.
While the evidence is not overwhelming or conclusive, there is consistent medium-quality scientific support for the use of DHA (particularly as part of fish oil supplements) as an adjunct to standard RA therapy. Guidelines from some rheumatology societies acknowledge the potential benefit but do not recommend omega-3s as a replacement for disease-modifying drugs.
