Official title
A Randomized, Double-Blind, Placebo-Controlled Decentralized Trial to Assess the Effect and Tolerability of Limosilactobacillus Reuteri DSM 17648 Supplement in Healthy Adults Reporting Upper Gastrointestinal Discomfort
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical trial is to learn if the food supplement containing a postbiotic (inanimate) Limosilactobacillus reuteri DSM 17648 works to improve the symptoms of upper gastrointestinal discomfort in healthy adults. The main questions it aims to answer are: 1. Does L. reuteri DSM 17648 reduce the frequency of the symptoms of upper gastrointestinal discomfort, including acid reflux-related and dyspeptic symptoms, and its relief rate, over 8 weeks of intake? 2. Does L. reuteri DSM 17648 improve gastrointestinal-related quality of life, and perceived stress? 3. How well do participants tolerate the L. reuteri DSM 17648 supplement? 4. Does L. reuteri DSM 17648 have an effect on the gut microbiota? (Exploratory aim) Researchers will compare supplement containing L. reuteri DSM 17648 to a placebo (a look-alike supplement capsule that contains no L. reuteri DSM 17648). Participants will: * Take L. reuteri DSM 17648 supplement or a placebo every day for 8 weeks * Answer questionnaires once every 2 weeks * Provide stool samples for microbiome assessment at 2 timepoints (baseline and end of study (8 weeks)) * provide weekly information on investigational product intake and any adverse event records
