Acacia fiber, also sold as gum arabic from Acacia senegal, is a non-viscous soluble fiber that colonic bacteria ferment, giving it prebiotic activity³. People take it for satiety and weight management, for glycemic and blood pressure support in adults at cardiometabolic risk, and for gut tolerance when other fibers cause bloating or thicken beverages. Trials also cover inflammatory markers in chronic kidney disease and sickle cell anemia.

Satiety trials in healthy adults found reduced hunger and lower subsequent energy intake². Lipid results are not consistent; one trial in hypercholesterolemic adults found no change. Products listing acacia fiber are mostly powders, with fewer capsules and liquids; see Form comparison.

The main caution is allergic: product labels warn that acacia is a legume in the peanut family and ask patients with peanut sensitivity to consult a practitioner first¹⁰. Bloating and flatulence appear at higher intakes and are generally mild¹.
