Inulin is a non-digestible prebiotic fiber that selectively feeds beneficial gut bacteria, particularly Bifidobacteria and Lactobacilli. This fermentation produces short-chain fatty acids (SCFAs) like butyrate, which support gut barrier integrity, reduce systemic inflammation, and improve metabolic health—all key factors in promoting healthspan.
Verdict
A cheap, effective, and evidence-backed tool for optimizing gut microbiome health.
