How Fibersol® works

In the small intestine
Fibersol® resists digestion during its short stop in the stomach and small intestine. The benefit? There’s virtually no increase in blood glucose when Fibersol® is consumed on its own.7

In the large intestine
Bacterial flora slowly and steadily ferments Fibersol® into short chain fatty acids (SCFAs) that promote the growth of gut-friendly microbes.

Result: less discomfort
SCFA production also lowers the colon’s pH—and the rate at which it drops indicates the degree of fermentation and off-gas.12 Since Fibersol® ferments slower than fibers like FOS or inulin, it has a slower decrease of pH and less rapid off-gassing as shown in studies, which translates into less gastrointestinal discomfort.12

How it stacks up to other fibers

Well tolerated vs. inulin and other soluble fibers, Fibersol® delivers all the desired benefits of dietary fiber—with minimal digestive intolerance or gastric discomfort. This high level of tolerance makes Fibersol® an ideal alternative to inulin.

digestive tolerance

Fibersol® prebiotic dietary fiber is a resistant maltodextrin associated with minimal gastrointestinal symptoms compared to inulin or FOS.

Over 30 years of extensive clinical research have proven Fibersol® to be well tolerated up to 68 grams per day.4
