简要总结
The purpose of this study is to investigate the effect of a GanedenBC30, a probiotic bacteria (Bacillus coagulans strain GBI-30, 6086), on the gut microbiome in healthy adults. Subjects will complete a 2-week run-in period prior to receiving GanedenBC30. The study is open-label and subjects will act as their own controls as the microbiome is unique to individuals. During the run-in period, subjects will collect two stool samples and complete daily bowel habit diaries in order to understand usual habits and profile the microbiome for each subject. 30 subjects will take part in this research study conducted at Nutrasource Diagnostics Inc. Subjects will take GanedenBC30 for four weeks. Stool samples will be collected at the end of the study and daily bowel habit diaries maintained for the duration of the study.
