Overview InformationInulin is a starchy substance found in a wide variety of fruits, vegetables, and herbs, including wheat, onions, bananas, leeks, artichokes, and asparagus. The inulin that is used for medicine is most commonly obtained by soaking chicory roots in hot water.
Inulin is commonly used by mouth for high blood fats, including cholesterol and triglycerides. It is also used for weight loss, constipation, diarrhea, and diabetes.
How does it work?Inulin is not digested or absorbed in the stomach. It goes to the bowels where bacteria are able to use it to grow. It supports the growth of a special kind of bacteria that are associated with improving bowel function and general health. Inulin decreases the body's ability to make certain kinds of fats.
Uses & Effectiveness
Possibly Effective for
- Constipation. Inulin seems to help relieve constipation in some children, adults, and elderly people. It increases the number of stools by up to about one per week. It also helps to make stools softer.
- Diabetes. Short-term use of inulin along with antidiabetes drugs may improve blood sugar levels in some people with diabetes. The benefit of long-term use is unclear.
- High levels of fats called triglycerides in the blood (hypertriglyceridemia). Taking inulin seems to lower triglycerides in some, but not all, people with high triglyceride levels.
- Obesity. Taking inulin seems to decrease body weight a small amount in adults who are overweight or obese. In obese children, inulin decreases the amount of body fat.
Insufficient Evidence for
- Diarrhea in people taking antibiotics (antibiotic-associated diarrhea). Some early research shows that taking inulin with a similar fiber called fructo-oligosaccharides does not prevent diarrhea in children who are taking antibiotics.
- Celiac disease. Some people with celiac disease may have trouble absorbing vitamins and minerals from food. Taking inulin might help children and teens with this condition absorb some vitamins. Inulin might also help these children and teens absorb iron.
- High cholesterol. It is unclear if taking inulin as a supplement lowers blood cholesterol in people with high cholesterol levels.
- Prediabetes. Some early research suggests that inulin does not improve the body's ability to manage insulin and blood sugar in people with prediabetes.
- Build up of fat in the liver in people who drink little or no alcohol (nonalcoholic fatty liver disease or NAFLD). Early research shows that taking the drug metronidazole for 1 week plus inulin for 12 weeks improves liver function in people with NAFLD. But taking inulin alone doesn't seem to have these positive effects.
- Other conditions.
Side Effects & SafetyWhen taken by mouth: Inulin is POSSIBLY SAFE in adults when used appropriately. The most common side effects occur in the stomach. They may include gas, bloating, diarrhea, constipation, and cramps. These side effects are more severe at high doses of inulin (more than 30 grams).
Special Precautions & Warnings:Pregnancy and breast-feeding: Inulin is POSSIBLY SAFE in pregnant and breast-feeding women when consumed in food. Not enough is known about the use of inulin as medicine during pregnancy and breast-feeding. Stay on the safe side and avoid use.
Children: Inulin is POSSIBLY SAFE in children when taken by mouth as a medicine, short-term.
We currently have no information for INULIN Interactions.
The following doses have been studied in scientific research:
- For constipation: 12-40 grams per day for up to 4 weeks.
- For diabetes: 10 grams per day for 8 weeks. Drinking 30 grams of inulin-containing milk powder dissolved in water before breakfast and 15 grams dissolved in water before dinner has been used for 12 weeks.
- For high levels of fats called triglycerides in the blood (hypertriglyceridemia): The usual dose of inulin is about 14 grams daily.
- For obesity: 10-30 grams per day for 6-8 weeks.
- For constipation: 4 grams per day for 6 weeks.
- For obesity: 8 grams per day for 16 weeks.
