Hyperuricemia, a common metabolic disorder characterized by elevated serum uric acid (UA) levels, can lead to severe complications such as gout and renal impairment. Conventional therapies, while effective, are frequently accompanied by significant adverse effects, underscoring the urgent need for safer therapeutic alternatives. Recent evidence identifies the intestine as a novel, pivotal regulator of UA homeostasis, presenting a promising therapeutic axis. This review delineates the intestinal mechanisms governing UA regulation and evaluates the therapeutic potential of natural active substances that target these pathways. We conducted a comprehensive review of recent preclinical studies focusing on intestinal mechanisms involved in UA metabolism, including the roles of gut microbiota, urate transport proteins, intestinal barrier function, and inflammation. Studies evaluating natural active substances—such as polyphenols, polysaccharides, peptides, and plant extracts—were systematically analyzed for their effects on gut-mediated UA regulation. Natural active substances have been shown to effectively alleviate hyperuricemia by modulating gut microbiota, enhancing UA intestinal excretion, reinforcing intestinal barrier function, and suppressing inflammatory pathways. Collectively, these findings demonstrate the multi-target efficacy of natural active substances within the intestines, offering a promising therapeutic strategy that warrants further investigation into nutrition-based intestinal interventions and novel pharmacological treatments for hyperuricemia.
