Inulin (Prebiotic Fiber)
Prebiotic fiber that selectively feeds Bifidobacteria and Lactobacilli, producing short-chain fatty acids for gut health and immunity.
Inulin is a type of soluble fiber found in many plants, particularly chicory root. It's classified as a prebiotic because it selectively feeds beneficial gut bacteria like Bifidobacteria and Lactobacilli. Fermentation of inulin produces short-chain fatty acids that support gut health, immunity, and metabolic function. It also improves calcium absorption and may help with blood sugar control and appetite regulation.

5-15g daily
Loading: Start with 3-5g and gradually increase over 1-2 weeks to minimize GI upset
Take with food
| Form | Type |
|---|---|
| ๐งชChicory root inulin powder | Recommended |
| ๐Inulin capsules | Alternative |
| ๐Inulin-FOS blend | Alternative |
Powder is most economical and easy to mix. Chicory root is the most common source. Often combined with FOS.
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: Not required
Note: Dissolves easily in water and beverages. Start low and increase slowly to allow gut adaptation.
Increased beneficial bacteria populations
Better bowel movement frequency and consistency
Increased satiety and reduced hunger
Common initial side effect as gut adapts
May worsen symptoms in FODMAP-sensitive individuals; start very low
High fiber may slightly affect absorption timing of some medications
May enhance blood sugar lowering; monitor if diabetic
Tip: Start low (3-5g) and increase gradually over weeks
Tip: Reduce dose; increase slowly
