Efficacy of a postbiotic and its components in promoting colonic transit and alleviating chronic constipation in humans and mice
Cell reports. Medicine (2025) · Animal · n=110
A randomized, double-blind, placebo-controlled crossover trial involving 110 adults with chronic constipation (Rome IV criteria) demonstrates that a 3-week Probio-Eco intervention significantly improves constipation symptoms, stool straining, and worry scores.
Based on meta-analyses showing FPG reduction of 0.59-0.82 mmol/L and HbA1c reduction of 0.63%. Studies primarily used berberine HCl with low bioavailability. Effects require divided doses and may take 8-12 weeks.
Based on SCFA studies showing 44% butyrate increase with Mediterranean diet intervention and gut barrier integrity improvements. Conservative estimates due to limited direct butyrate supplementation RCTs. Effectiveness varies significantly by form - tributyrin forms may show higher bioavailability.
