Quercetin is a plant-derived flavonoid found in many fruits and vegetables, known for its antioxidant and anti-inflammatory properties. Scientific interest in quercetin for cartilage damage primarily stems from its potential to modulate inflammation and oxidative stress, both of which contribute to the progression of cartilage degradation in conditions such as osteoarthritis. Preclinical studies (in vitro and animal models) have shown that quercetin can inhibit the production of pro-inflammatory cytokines (such as TNF-α and IL-1β), suppress cartilage-degrading enzymes (like matrix metalloproteinases), and reduce oxidative damage in chondrocytes, the cells responsible for maintaining cartilage tissue.

However, while laboratory and animal research is promising, direct clinical evidence in humans is limited. Few small-scale studies or clinical trials have evaluated quercetin supplementation specifically for cartilage damage or joint disorders. Some studies have investigated quercetin-containing plant extracts in osteoarthritis patients, but often these involve combinations with other bioactive compounds, making it difficult to attribute benefits solely to quercetin. Overall, the scientific evidence supporting the use of quercetin for cartilage damage is preliminary, and more robust, high-quality clinical trials in humans are needed to confirm efficacy and safety. Thus, while there is a scientific rationale for its use, current evidence does not strongly support its routine use for cartilage damage in clinical settings.
