A Probiotic Blend Reduces Gastrointestinal Symptoms and Positively Impacts Microbiota Modulation in a Randomized Study

Completed · Not applicable · Has a placebo group

Conditions studied: Microbiota, Constipation, Candida

In brief

This randomized, placebo-controlled, double-blind study will determine the effect of daily supplementation with a probiotic blend in 60 apparently healthy men and women recruited at a single investigational center in Northeast Ohio (i.e., The Center for Applied Health Sciences). Subjects will attend three study visits. During Visit 1, subjects will be screened for participation \[i.e., medical history, routine blood work, background baseline diet\]. During Visits 2 and 3 subjects will complete questionnaires that assess their gastrointestinal health (e.g., abdominal discomfort/bloating, constipation, regularity, stool consistency). Visits 2 and 3 will correspond to before (week 0) and after six weeks of supplementation, respectively, with the probiotic dietary supplement or placebo.
