Mung Bean Starch-Derived Fermented Liquid Alleviates Constipation via 5-HT Modulation and Gut Microbiota Regulation: An In Vivo Study

Background: Constipation is a common gastrointestinal disorder with a significant impact on quality of life. Methods: Constipation was induced in male ICR mice via 25% cotrimox- azole gavage (20 mL/kg/day for 7 days). Mice were divided into prevention (pre-MBSFL), treatment (MBSFL), and control groups.
