About

This clinical study aims to evaluate the use of i3.1 probiotic in participants who meet the Institute of Medicine (Canadian Consensus Criteria) case definition for ME/CFS and who may or may not be diagnosed with irritable bowel syndrome (IBS). The main questions it aims to answer are:

  • how effective is the usage of the i3.1 probiotic to reduce gastrointestinal (GI) inflammation and normalize the GI and systemic/brain interface?
  • how well is it working on IBS severity? The study sample is 100 male and female participants aged 45 to 70 years with ME/CFS (per the Canadian Consensus Criteria); one-half of the participants will have co-morbid IBS (per Rome IV criteria). Participants will receive an i3.1 or a placebo and be assessed at baseline, at eight weeks, and at 12 weeks (four weeks post-treatment completion).

Full description

This single-site comparison study will be performed on 100 participants, 45 to 70 years of age, who meet the Institute of Medicine (Canadian Consensus Criteria) case definition for ME/CFS and who may or may not be diagnosed with the irritable bowel syndrome (IBS), according to the Rome IV criteria. In this study, we will evaluate using the i3.1 probiotic compared to placebo. This is a randomized, placebo-controlled trial with four study arms that will include 25 participants per arm: Individuals with ME/CFS with and without IBS, who will take either the active medication i3.1 or placebo.
