Summary

Soluble fiber dissolves in water to form a gel-like substance, slowing digestion and nutrient absorption, which helps stabilize blood sugar. It is fermented by beneficial gut bacteria into short-chain fatty acids (SCFAs), supporting gut barrier function, immune modulation, and metabolic health. This process contributes to improved glucose control, reduced cholesterol, and a healthier gut microbiome, all critical for extending healthspan.

Purpose

Enhances gut health, improves metabolism, and lowers cardiovascular disease risk.

Card Summary

Forms a gel, supports gut bacteria, improves glucose and cholesterol, crucial for metabolic health and longevity.
