A soluble plant fiber, most often extracted from chicory root, that the body does not digest but that gut bacteria can ferment.

Why it’s used

Taken to support digestive regularity and as a prebiotic to feed beneficial gut bacteria.

What the evidence is for

prebiotic effects on gut bacteria and digestive regularity.

What the evidence says

Research on inulin-type fructans shows they are fermented by gut bacteria and can increase populations of certain beneficial species, with some studies also reporting improved stool frequency. Evidence for broader health claims beyond these digestive and microbial effects is less consistent.

Dose studied

5–20 g — studies on prebiotic and digestive effects.

Context

Studies examining digestive and prebiotic effects have generally used doses in the range of about 5 to 20 grams per day, with higher intakes more likely to cause bloating or gas.
