Official title
PHAGE 3: Determination of Phage and Probiotic Synergistic Effects on Gastrointestinal Health
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this double blinded clinical trial is to determine whether consumption of the PreforPro product, when co-consumed with Bacillus subtilis DE111 probiotic, synergistically improves bowel regularity, perceived physical symptoms of gastrointestinal distress and other aspects of gastrointestinal health over probiotic use alone. Therefore, the primary goal of this study is to see if PreforPro consumption concurrent with B. subtilis DE111 usage improves probiotic activity. The secondary goal of this study is to assess non-gastrointestinal physiologic parameters to determine whether consumption of PreforPro combined with the probiotic offers any additional health benefits (ie. reduced inflammation, improved gut microbiota profiles) beyond those of consuming a probiotic alone. Participants will be asked to track daily bowel movements for 7 days prior to beginning capsule consumption and record their diet for a total 3 of days (two weekdays and one weekend day). They will then be asked to consume the provided capsules daily for a period of 45 days. Researchers will compare three parallel arms; (1) PreforPro+B. subtilis DE111 probiotic, (2) B. subtilis DE111 alone, or (3) a maltodextrin placebo to establish their impact on gastrointestinal symptoms and other indicators of health.
