Chicory

Also known as: Cichorium intybus, chicory fiber, inulin from chicory, chicory root extract, Chicory root inulin

Overview

Chicory root inulin is a prebiotic fiber extracted from the root of the chicory plant, *Cichorium intybus*. This soluble fiber has garnered attention for its role in promoting gut health by selectively fostering beneficial bacteria including *Bifidobacterium*. In addition to its prebiotic properties, inulin is utilized in weight management and metabolic health improvement. The research surrounding chicory root inulin includes several systematic reviews and meta-analyses, indicating a moderate to strong level of evidence supporting its health benefits. However, further studies are recommended to explore its effects across different demographic populations and conditions more comprehensively. It is available in various forms, including powder and capsules, making it a versatile addition to dietary regimens focused on enhancing gut microbiome diversity and overall health.

Benefits

Chicory root inulin is particularly noted for its efficacy in supporting gut health, evidenced by its capacity to increase *Bifidobacterium* populations, enhance stool frequency, and soften stool consistency in both healthy individuals and those suffering from gastrointestinal issues. Systematic reviews have highlighted significant reductions in body weight, body mass index (BMI), and waist circumference with supplementation, particularly beneficial for diverse populations. The potential hepatoprotective effects for individuals with non-alcoholic fatty liver disease (NAFLD) are promising but necessitate further confirmation through research. Overall, healthy adults and those with NAFLD have exhibited the most evident clinical benefits, marked by modest weight reductions and improvements in liver enzyme levels.

How it works

Chicory root inulin functions as a prebiotic fiber, promoting the growth of beneficial gut bacteria such as *Bifidobacterium*, *Anaerostipes*, *Faecalibacterium*, and *Lactobacillus*. This fiber undergoes fermentation in the gut, resulting in the production of short-chain fatty acids that enhance satiety and influence metabolic health. The primary action of inulin occurs within the gut microbiome, where it not only improves localized gut health but also facilitates systemic benefits that can impact overall metabolic functions.

Side effects

Chicory root inulin is generally regarded as safe for most individuals; however, gastrointestinal discomfort, such as bloating and gas, may be experienced, especially at higher dosages. Mild allergic reactions can occur in sensitive individuals, though severe allergies are rare. Currently, no significant drug interactions have been documented, but caution should be exercised for those taking medications affecting gut motility. It’s advisable for individuals with severe gastrointestinal disorders to seek medical advice before using inulin. Pregnant or breastfeeding women should also consult healthcare providers before starting supplementation, given the lack of extensive research in these populations.

Dosage

To achieve health benefits, the minimum effective dosage of chicory root inulin is generally considered to be around 3 grams per day, with optimal dosages ranging from 5 to 20 grams daily. While it is regarded as safe up to a daily limit of 20 grams, to minimize gastrointestinal side effects, it is suggested to consume inulin with meals. Chicory root inulin is available in both powder and capsule forms, primarily functioning through fermentation in the large intestine rather than direct absorption in the small intestine.
