Diabetes constitutes a risk factor for cognitive impairment, whereas insulin resistance serves as the shared pathogenesis underlying both diabetes and decline. The use of metformin treating impairment remains controversial. present study found that hesperetin, flavanone derived from citrus peel, enhanced metformin's efficacy in reducing blood sugar levels, improving sensitivity, ameliorating diabetic rats. Additionally, it reduced required dosage to one-third its conventional dose. Transcriptome analysis 16S rRNA sequencing revealed activation cyclic-adenosine monophosphate response element binding protein (CREB)/brain-derived neurotrophic (BDNF) pathways benefited regulation gut microbiota promotion short-chain fatty acid (SCFA) producers such Romboutsia. Furthermore, this demonstrated hesperetin supplementation counteracted upregulation β-site amyloid precursor cleaving enzyme 1 (BACE1), pathological Alzheimer's disease (AD) was induced by metformin. Our findings reveal can be used supplementary treatment associated with diabetes.
