Natural polysaccharides (NPs), as a class of bioactive macromolecules with multitarget synergistic regulatory potential, exhibit significant advantages in diabetes intervention. This review systematically summarizes the core hypoglycemic mechanisms NPs, covering structure-activity relationships, integration gut microbiota-metabolism-immunity axis, and regulation key signaling pathways. Studies demonstrate that molecular weight, branch complexity, chemical modifications NPs mediate their activity by influencing bioavailability target specificity. improve glucose metabolism through multiple pathways: activating insulin signaling, improving resistance (IR), enhancing glycogen synthesis, inhibiting gluconeogenesis, regulating microbiota homeostasis. Additionally, protect pancreatic β-cell function via nuclear factor E2-related 2 (Nrf2)/Antioxidant Response Element (ARE) antioxidant pathway Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) anti-inflammatory pathway. Clinical application still requires overcoming challenges such resolving complex relationships dynamically integrating cross-organ signaling. Future research should focus on multi-omics technologies (e.g., metagenomics, metabolomics) organoid models to decipher action networks promote translation from basic clinical applications.
