Changes in Microbiota and Quality of Life in IBS

Status unconfirmed · Not applicable · Has a placebo group

Conditions studied: IBS - Irritable Bowel Syndrome

In brief

The primary research question to be addressed is: Does a 2'-FL-containing dietary supplement impact stool microbiota composition in adults with IBS? The primary measure for determining potential impacts of the 2'-FL-containing dietary supplement on stool microbiota composition is stool abundance of Faecalibacterium prausnitzii, a commensal intestinal bacteria. Additional measures related to determining potential impacts of the 2'-FL-containing dietary supplement on gut microbiota composition are stool levels of additional commensal intestinal bacteria and measures of intestinal microbial diversity.
