Summary

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.

Purpose

A prebiotic fiber that feeds beneficial gut bacteria.

Card Summary

A prebiotic fiber that selectively feeds beneficial gut bacteria, producing short-chain fatty acids (SCFAs) like butyrate, which support gut barrier integrity and reduce inflammation.
