Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of the clinical trial portion of this study is to assess whether an individualized dietary plan based on a commercial food sensitivity assay provides specific benefit in a randomized controlled trial in adults with irritable bowel syndrome (IBS).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a parallel group, randomized control trial, powered to assess changes in validated outcomes in adult patients with symptomatic irritable bowel syndrome. Subjects will receive dietary counseling and be asked to adhere to dietary instructions for 4 weeks. Assessments will occur at baseline, 4-weeks, and 8-weeks post-baseline.
