What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Fibers and probioticsDietary supplement
A blend of fibers and seven probiotics
| Study group | Role | What they receive |
|---|---|---|
| Nutrition intervention | Experimental | Ingestion of fibers and probiotics daily for 22 days Receives: Dietary Supplement: Fibers and probiotics |
| No intervention | No intervention | No intervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
Minimizing microbiota composition change
Shotgum metagenomics
Measured: Daily from Day -4 to day + 7 (Day 0 is the start of the challenge)
Secondary outcomes (3)
Increased intestinal microbiota diversity
Measured by the Shannon diversity index
Measured: Daily from Day -4 to day + 7 (Day 0 is the start of the dietary challenge)
Increased microbiota gene richness
Measured by gene counts from metagenome sequencing of the fecal microbiota
Measured: Daily from Day -4 to day + 7 (Day 0 is the start of the dietary challenge)
Gut comfort
Assessed each Gastrointestinal Symptoms (VOMITING, NAUSEA, AUDIBLE BOWEL SOUNDS, FLATULENCE, ABDOMINAL CRAMPS, BLOATING ) with a scale (from 0 to 10, 10 being the worst outcome)
Measured: Daily from Day -10 to day + 7 (Day 0 is the start of the dietary challenge)

Who may be eligible to take part?
The sponsor lists 4 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Minimizing microbiota composition change (time frame: Daily from Day -4 to day + 7 (Day 0 is the start of the challenge)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Nov 2020; AzTrials last refreshed its copy on 8 Nov 2026.
