Source of validity: Traditional
Rating (out of 5): 2

Evening primrose oil (EPO) has been traditionally used to support joint health, largely due to its content of gamma-linolenic acid (GLA), an omega-6 fatty acid believed to have anti-inflammatory properties. Historically, EPO has been used in folk medicine for conditions involving inflammation, such as rheumatoid arthritis (RA). However, the scientific evidence supporting its efficacy for joint health is limited and inconsistent.

Some small clinical trials and observational studies have explored the effects of EPO on joint pain and stiffness, particularly in people with RA. While a few early studies suggested modest improvements in symptoms such as morning stiffness and pain reduction, subsequent and more rigorous research has failed to confirm significant or consistent benefits. Major health organizations, including the Arthritis Foundation and Cochrane Reviews, generally conclude that evidence is insufficient to recommend EPO as a reliable treatment for joint disorders.

In summary, the use of evening primrose oil for joint support is rooted in traditional practices and historical use rather than robust scientific validation. While some individuals may report subjective benefits, current clinical evidence does not strongly support its efficacy for joint health, and its use should be considered with caution, especially as an alternative to evidence-based therapies.
