What does the evidence say about Chicory Root Fiber Blood Glucose Randomized Trial?

Updated August 2026

Quick Answer

Chicory Root Fiber Blood Glucose Randomized Trial has evidence relevant to benefits, uncertainty, and practical interpretation, but conclusions should stay close to the cited sources. One representative finding is: Clinically, chRG-I was well-tolerated and slightly improved stool consistency compared to placebo.

Key Takeaways

  • 01Clinically, chRG-I was well-tolerated and slightly improved stool consistency compared to placebo. [Kerezoudi EN (2026)]
  • 02In an intestinal barrier challenge model, chRG-I fermentates (a pool of metabolites including SCFA and fragments of chRG-I) protected barrier integrity, modulated the cytokine milieu away from a predominantly pro-inflammatory response, as characterized by increased IL4 and IL22 and reduced IL9, IL17A, and IL21. [Kerezoudi EN (2026)]
  • 03Conclusion: Supplementation with a low dose of chRG-I is well-tolerated, beneficially modulates the gut microbiome - which can protect the intestinal barrier, and subtly enhances systemic immune readiness, suggesting that chRG-I may have benefits as a functional food ingredient. [Kerezoudi EN (2026)]
  • 04Background: Pectic rhamnogalacturonan-I (RG-I) is a dietary fiber that modulates the gut-immune axis. [Kerezoudi EN (2026)]

This answer focuses on benefits, uncertainty, and practical interpretation. - Clinically, chRG-I was well-tolerated and slightly improved stool consistency compared to placebo.

[Kerezoudi EN (2026); evidence level 4] - Interestingly, we previously found that short-term (3 weeks), daily intake of 30 g/day of dried chicory root fibers in individuals at risk of T2D rapidly modulated the gut microbiota by increasing relative levels ofspp. [Omary Lina (2025); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
