Flavonones, a subclass of flavonoids commonly found in citrus fruits (such as hesperidin and naringenin), have been investigated for their potential anti-inflammatory and antioxidant effects, which are relevant to arthritis pathophysiology. Preclinical studies (in vitro and animal models) demonstrate that flavonones can reduce inflammatory markers (such as TNF-α, IL-1β, and COX-2) and suppress oxidative stress, both of which play roles in the progression of arthritis. Some studies have shown that specific flavonones can alleviate symptoms in animal models of rheumatoid arthritis and osteoarthritis by modulating immune cell activity and inhibiting cartilage degradation.

However, clinical evidence in humans is limited. Few small-scale clinical trials or observational studies have evaluated the direct impact of flavonone supplementation on arthritis symptoms, and those that exist often involve mixed flavonoid supplements rather than isolated flavonones. Systematic reviews of flavonoids for arthritis generally report promising preclinical results but highlight a lack of robust human data. Consequently, while there is a plausible biological rationale and encouraging preliminary results, the overall evidence supporting flavonones for arthritis remains low, and they cannot be considered a validated treatment option at this time.

In summary, the use of flavonones for arthritis is based on emerging scientific evidence, primarily from laboratory and animal studies. More rigorous human trials are necessary to confirm their efficacy and safety for this indication.
