Inulin Side Effects

What is inulin?

Inulin 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.

Inulin Side Effects

Inulin Side Effects

When 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).

Inulin belong to a class of dietary fibers known as fructans which are high FODMAP oligosaccharides. For those with irritable bowel syndrome even small doses like 0.5 to 1 gram can cause gas, bloating, abdominal pain, and diarrhea.

Inulin side effects gas

If you're like most Americans, you’re trying to add more fiber to your diet. That’s a good thing, because the average American gets only half the recommended amount of fiber each day. Manufacturers are responding to consumers’ wishes by adding fiber to a plethora of foods and beverages, including cereals, energy bars, protein supplements, “healthier” cookies, diet ice cream and even bottled water.

One of the most prevalent fiber-boosting ingredients is inulin. Like any fiber, it can cause gas, bloating and abdominal pain if consumed too quickly or in large quantities. Many of my clients who have complained about digestive discomfort don’t realize how much inulin they’re consuming each day. Most of them have never even heard of it.

Chitinase is a type of enzyme sometimes used in medical treatments, particularly in anti-fungal creams and lotions. I don’t know of any research supporting its value as an additive to probiotic supplements or foods.

The makers of many probiotics include additional ingredients with the hope of making their products more effective. And often times, they can make a good case for a particular ingredient. Take, for example, prebiotics, which are designed to provide nutrient support to the probiotic organism or otherwise improve its survival in the digestive tract. Prebiotics include inulin, oligosaccharides and various types of dietary fibers.

Some prebiotics are sold separately from probiotic organisms in order to foster the good organisms naturally present in the intestinal tract. These prebiotic products may be particularly helpful for those who don’t tolerate probiotics well. But just like probiotics, prebiotics can have side effects such as increased gassiness and unwanted stool changes such as diarrhea or constipation.

Inulin side effects nausea

Side effects of inulin typically involve the digestive system. Some people may experience stomach pain and gas if they consume too much inulin. Other common side effects include feelings of nausea and diarrhea. Usually, side effects occur if people unknowingly eat foods with added inulin or take inulin supplements. It is possible for inulin to cause an allergic reaction in some people.

Inulin intolerance

Inulin intolerance

What is a fructans intolerance or sensitivity?

We all lack the necessary enzymes to break down these long chains of fructose molecules. Our bodies are unable to digest inulin in the small intestine. This means it will always travel along to the large intestine, where some level of fermentation will occur. Thankfully, the bacteria in our gut have the necessary enzymes to break down these undigested sugars. However for some of us (depending on our mix of gut microbes), even the smallest amount of gas produced can result in very uncomfortable digestive symptoms.

Many people unnecessarily avoid gluten (a protein found in wheat products), because they experience digestive symptoms after eating wheat based products. Maintaining a gluten free diet is only required if you have been diagnosed with coeliac disease. Potentially, the source of your digestive issues is the presence of fructans in foods, rather than gluten. Continue reading to find out how you can test this.

inulin function(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.

Research into the bacteria and microbes in the gut is in its infancy. There’s a population of billions of them inside you right now, and scientists are only just now starting to figure out their effect on the digestive system and the body as a whole. Individual species can have different effects when combined with favourable conditions or certain cells within the large intestines, making experimentation slow. The benefits are worth the effort, though, and prebiotics like inulin not only contribute to eased sleep, but may prove to have benefits yet to be discovered.

Now may be a great time to start adding inulin into your diet, whether it’s using it in your coffee or tea, or adding it to your daily smoothie. Even aside from being a sleep aid, inulin can aid your digestive system and is also an excellent source of fibre. If you have any concerns about taking inulin for any reason, consult your doctor to see if it conflicts with any conditions or medication you may be taking.

inulin foods

Inulin 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.

Chicory root fiber side effects

Chicory root fiber side effects

When taken by mouth: Chicory is LIKELY SAFE for most adults when consumed in amounts found in food. Chicory root extract and chicory seed are POSSIBLY SAFE for most adults when taken by mouth in medicinal amounts, short-term. Taking chicory by mouth might cause minor GI side effects including gas, bloating, abdominal pain, and belching. There isn't enough reliable information to know if chicory is safe to use orally, long-term, or what the side effects might be.

When applied to the skin: There isn't enough reliable information to know if chicory is safe. Some reports show that handling the chicory plant might cause skin irritation.

How to take inulin powder?



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.
