<b>Conclusions</b>: In conclusion, CPCM ameliorates glucose and lipid metabolic disorders in T2DM through multiple mechanisms: reshaping the intestinal probiotic community, enhancing its beneficial metabolic functions, restoring the activity of the PPARγ-LXRα signaling pathway, and subsequently downregulating NPC1L1. Here, NPC1L1 is linked to type 2 diabetes mellitus.
