Mechanism of Action

Sunfiber® is a “true regulating” fiber in that it helps not only with constipation, but also with occasional diarrhea; returning the stool to a normal state. Sunfiber® helps to improve the beneficial probiotics within the intestinal tract, including Bifidobacteria and Lactobacillus. SunFiber ® slows the gastric transit time and increases the satiation hormone CCK resulting in a comfortable full and satisfied feeling. It also improves absorption of minerals including Ca, Fe, Zn, and Mg.

Clinical Studies

Sunfiber® is one of the most extensively studied fibers with almost 180 published papers and over 120 clinical studies. All established digestive claims are supported by clinical studies and science.

Formulating With Sunfiber®

Sunfiber® is completely soluble in water, creating a tasteless, colorless, odorless, very low viscosity solution.


Sunfiber® is GRAS. In August 2016, the U.S. Food and Drug Administration, Department of Health & Human Services, confirmed that Sunfiber® is a dietary fiber.
