Phenolic acids are a group of plant-derived compounds known for their antioxidant and anti-inflammatory properties. Scientific interest in their potential for arthritis, particularly osteoarthritis and rheumatoid arthritis, has grown in recent years due to these biological activities. Several in vitro and animal studies have demonstrated that certain phenolic acids (such as caffeic acid, ferulic acid, and p-coumaric acid) can inhibit pro-inflammatory cytokines (e.g., TNF-α, IL-1β) and reduce oxidative stress, both of which play key roles in the pathogenesis of arthritis. For example, studies on rodent models of arthritis have shown that administration of phenolic acids can decrease joint inflammation, cartilage degradation, and pain-related behaviors.

However, human clinical evidence remains limited. A few small-scale trials and observational studies suggest that diets rich in polyphenols (including phenolic acids) may be associated with reduced markers of inflammation and improved joint function, but these studies often involve complex mixtures (such as whole foods or plant extracts) rather than isolated phenolic acids. Thus, while laboratory evidence supports a plausible mechanism of action, the direct clinical benefit of phenolic acids for arthritis has not been firmly established. More rigorous, controlled clinical trials are needed to confirm their efficacy and optimal dosage in human populations.
