The purpose of this study is to determine whether a modified formulation and daily intake schedule of SBD111 results in similar levels of probiotic microbes in the gut compared with the currently used formulation. SBD111 is a food made of probiotic microbes (bacteria and yeast) and prebiotic dietary fibers (a form of fiber obtained from diet). SBD111 is a medical food used for the dietary management of postmenopausal bone loss.SBD111 was previously found to be safe and well tolerated in a human clinical safety study and a clinical efficacy study. Study participation will include a screening virtual visit, periodic remote questionnaires and check-in calls, and three at-home stool swab sample collections. Eligible participants will be assigned to one of two SBD111 study groups evaluating different formulations and dosing schedules. Each day for a 28-day period, they will take (i) two capsules once daily or (ii) two capsules twice daily (morning and evening), depending on the study group assigned. Investigators will collect demographic information and will ask questions related to dietary intake, bowel habits, and health history. Upon enrollment into the study, participants will receive six at-home stool sample collection kits, two each for baseline, Week 1, and Week 4 analysis. Samples will be collected at home and mailed to a SĹŤlaria BiĹŤ for analysis of the bacterial community that lives in the intestine (the gut microbiome). During the study, participants will also be asked to complete brief questionnaires related to gastrointestinal symptoms, cognitive function, well-being, and sleep. On days 7 and 28 of the study, they will be asked to complete a brief adherence questionnaire and discuss any adverse (negative) events. All participants will receive compensation in the form of gift cards for completing study procedures and returning stool samples. Participants will receive a $50.00 gift card after completing the Week 1 study procedures and after receipt of the mailed baseline and Day 7 stool swab samples. Participants will receive a $150.00 gift card after completing the Week 4 study procedures and after receipt of the mailed Week 4 stool swab sample.
