Today we move to the letter “I” in our ingredient A to Z series and we are featuring inulin as our ingredient of the day.
What is inulin?
According to Wikipedia, inulins are a group of naturally occurring polysaccharides produced by many types of plants. Inulins are dietary fibers that are classified and known as fructans. Chicory is a common source for commercially utilized inulin. Inulins belong to a class of dietary fibers known as fructans.

Why is inulin included in dog food?
Inulin is added to dog food for two key reasons: 1) it is somewhat sweet and can be used to increase a food’s sweetness even though it is a relatively low calorie alternative to other fats or sugar and 2) it can be used as a prebiotic to aid digestion.
Is inulin a commonly used ingredient in dog food?
We found inulin in 6.10% of the foods in our dog food ingredient database. We then searched for the broader term “fructooligosaccharide” and found this in 8.1 % of all dog food.
Common benefits or risks of inulin
There are many benefits of inulin. Inulin is a low calorie carbohydrate and fiber source with about 25% less calories than sugar and about 10-12% less calories than fat. Inulin can increase calcium absorption and can be characterized as a prebiotic, which is a substance that feeds the healthy bacteria in the body’s intestinal system.
Too much inulin can produce bloating, gas, and diarrhea in some people, as would most any diet with too much fiber. We have not found any research studies related to the levels of inulin needed to cause similar gastric distress in dogs.
