What this trial studies

This study aims to evaluate the prebiotic effects of novel RG-I variants derived from chicory and carrot on gut health. Participants will receive either RG-I or a placebo in a randomized, double-blind, placebo-controlled design. The study will assess changes in gut microbiota, short-chain fatty acid profiles, and inflammatory markers through fecal and blood samples. The goal is to understand how these dietary fibers can modulate gut health and immune responses.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18-70 with a BMI between 18.5 and 30.0 who can abstain from prebiotic and probiotic products prior to the study.

Not a fit: Patients with gastrointestinal disorders, psychiatric diseases, or those on certain medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new dietary interventions that improve gut health and reduce inflammation.

How similar studies have performed: While the specific RG-I variants are novel, similar studies have shown promise in using dietary fibers to modulate gut health.
