Inulin is a type of fiber that's found in certain plant foods. Chicory root is the main source of inulin in supplement form.
Chicory was originally found in Europe and Asia. Egyptians grew it thousands of years ago as a medicine. It's now grown in the U.S.
Your small intestine does not absorb inulin. When it reaches your large intestine (colon), bacteria ferment it.
Why do people take inulin?
People often use inulin to try to treat or prevent digestive problems.
Increase helpful bacteria in the colon. Because it has this effect, inulin is called a prebiotic. Prebiotics may have numerous health benefits. They may:
- Help increase the amount of calcium and other minerals you absorb from food
- Support a healthy immune system
- Relieve intestinal problems
Suggested dosages vary by supplement maker. Optimal doses of inulin have not been set for any condition. Quality and active ingredients in supplements may vary widely from maker to maker. This makes it hard to set a standard dose.
Can you get inulin naturally from foods?
Many foods -- and plants that are less commonly eaten -- contain inulin. These include:
- Chicory, which is used in salads
- Dandelion root
- Jerusalem artichokes
Inulin is found in some processed foods as a replacement for fat, such as:
- Candy bars
- Ice cream
When combined with water in a precise way, it can mimic the texture of fat in these foods.
What are the risks of taking inulin?

Inulin may also cause:
Risks. Inulin-type prebiotics are generally recognized as safe. Check with your doctor about taking supplements if you are pregnant or breastfeeding. Chicory may also interfere with certain drugs and supplements.
The U.S. Food and Drug Administration (FDA) does regulate dietary supplements; however, it does not treat them the same as foods or drugs. The manufacturer is responsible for the safety and labeling of their own product.
