Prebiotic Inulin
A soluble fiber that feeds beneficial gut bacteria.
Also known as: Inulin • Chicory Root Fiber
Overview
Inulin is a type of soluble fiber found in many plants. It is a fructan, meaning it is made up of chains of fructose molecules. Since it is not digested or absorbed in the small intestine, it travels to the lower gut, where it functions as a prebiotic, feeding the beneficial bacteria in the gut.
Key Benefits
Promotes a Healthy Gut Microbiome
Inulin acts as a prebiotic, stimulating the growth of beneficial bacteria such as Bifidobacteria and Lactobacilli in the gut.
Enhances Calcium and Magnesium Absorption
Studies have shown that inulin can increase the absorption of calcium and magnesium, which is important for bone health.
Helps Control Blood Sugar
By slowing digestion, inulin can help prevent spikes in blood sugar levels after meals.
Dosage & How to Take
Start with a small dose of 2-3 grams per day and gradually increase to 5-10 grams as tolerated. It can be mixed with water, juice, or added to food.
| Purpose | Dose | Notes |
|---|---|---|
| Gut Health Maintenance | 5g | Take daily with a meal. |
| Improved Mineral Absorption | 8-10g | Split into two doses per day. |
| Blood Sugar Management | 10g | Consume before or during a high-carb meal. |
Best Time to Take
Can be taken at any time of day, but may be most effective when taken with meals.

Scientific Research
Effects of chicory inulin on gut microbiota
A 2017 review in the journal Nutrients concluded that inulin selectively stimulates the growth of beneficial bacteria in the gut.
Inulin-type fructans and calcium absorption
A 2005 study in The American Journal of Clinical Nutrition found that inulin-type fructans significantly increase calcium absorption in adolescents.
