10 Amazing Health Benefits of Chicory Root (Backed by Science)

Chicory Benefits

Chicory root spent a few centuries as a coffee stretcher. These days it shows up on ingredient labels as "chicory root fibre," usually next to a health claim. So what does it actually do for the body?

Researchers have tested it, mostly through inulin, the fibre the root stores. Some of the results are solid. Others come from small trials or from animals, and "amazing" does not fit every item on this list equally well. I have marked how strong the evidence is for each one. One thing to keep in mind as you read: most studies used measured doses of extracted inulin, with a median of about 10 grams a day in one large review [6], not a cup of chicory coffee.

1. It feeds friendly gut bacteria

Evidence: strong

Chicory root is the main commercial source of inulin [1]. Human digestive enzymes cannot break inulin down, so it reaches the colon intact, where bacteria ferment it [1].

A systematic review and meta-analysis of 50 randomised controlled trials found that chicory-derived inulin and oligofructose raised Bifidobacteria, a group of gut bacteria, in healthy people and in groups with health conditions. The exception was people with gastrointestinal disorders [3]. A summary of the review reported effects starting at around 3 grams a day [4]. The findings were publicised by BENEO, a chicory fibre supplier [4], so it is sensible to read the original paper before repeating them.

2. It can make bowel movements more regular

Evidence: moderate

The same review reported better bowel regularity, with more frequent stools in healthy adults and softer stools in healthy infants and children [4]. Healthline also describes a 2017 study of 44 people with constipation, where four weeks of chicory inulin improved stool frequency and softness compared with placebo [5].

More is not always better. At 15 to 50 grams a day, inulin increases how often people pass stool [1], which is another way of saying that large amounts can send you running to the bathroom.

3. It may lower blood sugar markers in prediabetes and type 2 diabetes

Evidence: strong for glucose and HbA1c, weaker for insulin

A 2019 meta-analysis in the Journal of Translational Medicine pooled 33 randomised trials with 1,346 participants. In the subgroup with prediabetes or type 2 diabetes, inulin-type fructans were linked to an average drop of 0.60 mmol/L in fasting glucose and 0.58 percentage points in HbA1c. The authors rated their confidence in both results as high. Fasting insulin and insulin resistance (HOMA-IR) also fell, but with low certainty [6].

Doses in the trials ran from 5.5 to 30 grams a day, and the authors suggested 10 grams a day for six weeks or longer. They described it as a possible add-on to treatment, not a replacement [6]. We go through this in more detail in our article on whether chicory is good for diabetics.

4. It may help a little with weight

Evidence: moderate, with a modest effect

A 2025 meta-analysis of 32 randomised trials, published in The American Journal of Clinical Nutrition, looked at chicory inulin-type fructans and weight. Across 29 trials with a median dose of 10 grams, body weight fell by an average of 0.97 kg. BMI dropped by 0.39 kg/m² and waist circumference by 1.03 cm [7].

That is under a kilogram, which is useful at best and not a diet. There are two other things to know. The study was funded by the Beneo Institute, set up by a chicory fibre supplier, and one co-author works for Beneo. The results also varied a lot from one trial to the next [7].

5. It may lower LDL cholesterol slightly

Evidence: limited

A 2017 meta-analysis of 20 randomised trials with 607 adults found that inulin-type fructans lowered LDL cholesterol slightly. HDL cholesterol rose only in the type 2 diabetes subgroup [8].

The drop was small. The authors also detected possible publication bias, had few trials in the diabetes group, and called for larger, longer trials before firm conclusions [8]. Treat this one as a maybe.

6. It may help your body absorb more calcium

Evidence: early

In a randomised, placebo-controlled crossover trial with 54 participants, 8 grams a day of inulin enriched with oligofructose, taken for three weeks, raised calcium absorption from 33.1% to 36.1%. The people who absorbed the least calcium at the start gained the most [9].

Three percentage points is a modest change, it is one trial, and the product was a specific inulin blend. Please do not swap calcium-rich food for chicory.

7. The leaves carry real vitamins

Evidence: nutrition data

So far we have talked about the root. The leaves are a different story. Raw chicory leaves are about 92% water and give 23 calories per 100 grams. They supply more than 20% of the Daily Value of vitamin K, vitamin A and vitamin C, along with some B vitamins and manganese [2]. Wikipedia also notes that the whole plant is edible [2].

Those figures describe raw leaves. They say nothing about a cup of roasted-root coffee. If you want to know how the plant is grown before it reaches your plate or your cup, our guide to how chicory is grown and where it's found covers it.

8. It gives coffee drinkers a caffeine-free option

Evidence: simple fact

Chicory root is naturally caffeine-free, so pure chicory coffee has none. For comparison, a typical cup of regular coffee has about 92 mg, according to USDA data cited by Healthline [5]. The roots are baked, roasted and ground, and used as a coffee substitute or additive in many places [2]. Our history of chicory explains how that habit started.

To be fair, Healthline says there is no evidence that chicory coffee is healthier than regular coffee, and that the nutrient amounts in the finished drink are fairly low [5]. Its main appeal is being a substitute for people cutting back on caffeine.

9. It may calm inflammation, but only in animals so far

Evidence: early, animal studies

Healthline reports that studies in rats, piglets and a gout model in rats showed lower inflammatory markers after chicory was given. It adds that human research is still needed [5].

I include this one because you will see it claimed elsewhere. It is an interesting lead, not a proven benefit for people.

10. It helps you reach your daily fibre target

Evidence: general nutrition guidance

Inulin counts as dietary fibre [1], and food makers use chicory root inulin as a source of it [2]. The CDC cites the Dietary Guidelines for Americans, 2020 to 2025, which recommend 22 to 34 grams of fibre a day for adults, depending on age and sex. The CDC also says soluble fibre forms a gel in the stomach that slows digestion, which helps regulate blood sugar and cholesterol [10].

The CDC's advice on adding fibre is to go slowly and drink plenty of water [10]. A sudden jump can cause bloating, gas, constipation, diarrhoea or cramps [10].

Who should be careful

Regular inulin use can cause stomach discomfort, bloating, gas and diarrhoea, and people with an allergy to inulin can develop stomach inflammation [1]. Healthline says people allergic to ragweed or birch pollen should avoid chicory. It also advises anyone who is pregnant or breastfeeding to check with a doctor first, because safety research is limited, and to stop if symptoms like mouth pain, swelling or tingling appear [5].

If you manage diabetes or take medication, talk to your doctor or dietitian before adding fibre supplements. This article is general information, not medical advice.

So where does that leave you?

Chicory root has a real, well-tested effect on gut bacteria and some evidence for blood sugar and bowel regularity. For weight, cholesterol and calcium, the results are small or early. For inflammation, they are animal data only. That is still a decent record for a plant most people drive past.

For food and beverage businesses

If you formulate products with chicory, the root comes in several forms. Our guide to types of chicory products explains how roots, cubes, powder, granules and extract differ, and our chicory root guide for beginners covers the basics. You can look at our roasted chicory granules, chicory powder and chicory extract, or browse the full chicory products range.
