Roll Call does not check drug interactions or assess personal safety.
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.
