    Endogenous Metabolite Infection Neurological Disease Metabolic Disease Cancer
    Inulin is an orally active prebiotic targeting the intestinal microbiota, selectively promoting the proliferation and activity of beneficial bacteria such as bifidobacteria and lactic acid bacteria, and playing a role in regulating the intestinal microecology. The functions of Inulin include: Fermentation by probiotics in the colon to produce short-chain fatty acids (such as butyrate and propionate), lowering the intestinal pH and inhibiting the overgrowth of harmful bacteria; Enhancing the intestinal barrier function and reducing endotoxin translocation; Directly scavenging free radicals (such as superoxide free radicals, hydroxyl free radicals) and activating antioxidant enzymes (SOD, CAT) to reduce oxidative stress. Inulin can also be used in the study of intestinal diseases (constipation, IBD), metabolic syndrome (diabetes, obesity) and liver damage by regulating glucose and lipid metabolism (such as reducing triglycerides, improving insulin sensitivity) and immune response (enhancing NK cell activity, inhibiting inflammatory factors)[1][2][3][4].
