ClinConnect Summary

This clinical trial is focused on collecting stool samples from healthy volunteers to study the digestive system and its bacteria. By understanding the gut microbiota, researchers hope to gain insights that could improve digestive health. The study is looking for participants aged 18 to 60 who are generally healthy, have regular bowel movements, and a body mass index (BMI) between 18.5 and 30. Participants must be able to collect their stool samples and deliver them to the research site, speak and read in French, and follow specific dietary guidelines during the study.

If you meet these criteria and decide to participate, you'll need to avoid certain foods, supplements, and medications that could affect your gut health for the duration of the study. It’s important to maintain your usual routine and not make significant lifestyle changes during this time. While the study is not currently recruiting, it offers a chance to contribute to important research that may help improve our understanding of digestive health.
