Official title
Examining the Impact of Weizmannia (Bacillus) Coagulans JBI-YZ6.3 on Gut Health and Fecal Microbiome Changes
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will evaluate the effects of supplementation with Weizmannia (Bacillus) coagulans JBI-YZ6.3 on gastrointestinal health in healthy, physically active adults. The primary objective is to determine whether daily intake of this probiotic strain improves symptoms of constipation and related gastrointestinal function compared with placebo. Approximately 30 healthy men and women aged 18 to 50 years will be enrolled in a randomized, double-blind, placebo-controlled, crossover trial. Participants will complete two 4-week supplementation periods, one with Weizmannia (Bacillus) coagulans JBI-YZ6.3 and one with placebo, separated by a 4-week washout period. The total duration of participation will be approximately 13 to 14 weeks, including screening and testing visits. Gastrointestinal symptoms will be assessed at baseline and after each supplementation period using validated questionnaires, with particular focus on the constipation domain of the Gastrointestinal Symptom Rating Scale (GSRS). Secondary outcomes will include additional gastrointestinal symptom domains and markers of perceived gut comfort and function. This study is designed to determine whether supplementation with Weizmannia (Bacillus) coagulans JBI-YZ6.3 produces clinically meaningful improvements in gastrointestinal symptoms in physically active adults compared with placebo.
