An Evaluation of the Effectiveness of a Proprietary Probiotic Blend on Functional Constipation

A Randomized, Double-Blind, Placebo-Controlled, Parallel Study to Evaluate the Effectiveness of a Proprietary Probiotic Blend on Functional Constipation

The primary objective for this study is to monitor the change in patient assessed symptoms of constipation in subjects taking the proprietary probiotic blend compared to those taking the placebo. The secondary objective for this study is to additionally monitor changes in stool consistency, stool frequency, quality of life and microbial composition of feces from baseline to Day 29, in all subjects. Safety considerations monitored any changes in blood safety parameters as well as incidence of adverse events throughout the entire study for all subjects.
