This study examines the potential of polyphenols for treating IBD, with an emphasis on modulating cellular signalling mechanisms, regulating the balance of gut microbiota, and restoring the epithelial barrier. The available evidence concluded that the utilization of polyphenol-rich sources could control inflammation, mucosal healing, and positive benefits with minimal side effects. Even though additional study is required in this area, particularly that which focuses on the interactions, connections, and precise mechanisms of action linking polyphenols and IBD.
