Summary

Partially Hydrolyzed Guar Gum is a soluble, non-viscous, prebiotic fiber derived from the guar bean. It is fermented by gut bacteria into short-chain fatty acids (SCFAs) like butyrate, which serve as a primary energy source for colon cells and help maintain gut barrier integrity. By selectively feeding beneficial bacteria, PHGG supports a healthy microbiome, which is foundational for modulating systemic inflammation, metabolic health, and immune function.

Purpose

A prebiotic fiber that nourishes the gut microbiome.

Card Summary
