WHAT IT DOES
A natural tree sap fiber that doubles as a prebiotic and a clean supplement binder.

DOES IT WORK?
Acacia gum (gum arabic) is a soluble fiber from the Acacia senegal tree. It's one of the better-tolerated prebiotic fibers, causing less gas than inulin or FOS. Clinical studies show it increases Bifidobacteria, supports weight management, and may help lower BMI. In supplements, it often serves double duty as both a binder and a functional fiber. A solid natural ingredient.
