Evaluating Efficacy of Investigational Products on Spontaneous Bowel Movements in Healthy People With ≤ 3 Complete Weekly Spontaneous Bowel Movements

A Single-center, Randomized, Double-blind, Placebo-controlled, Parallel Study to Evaluate the Efficacy of the Investigational Products on Complete Spontaneous Bowel Movements in Participants Who Normally Have ≤ 3 Complete Spontaneous Bowel Movements Per Week But Are Otherwise Healthy

Low and High doses of Actazin and Livaux will be compared against a control formula and placebo to evaluate how each investigational study product effects complete spontaneous bowel movements in healthy adults that currently experience less than or equal to 3 complete spontaneous bowel movements per week. During the 28-day study period, it is hypothesized that participants consuming Acatzin, Livaux, or control formula will have an increased number of complete spontaneous bowel movements when compared to participants consuming the placebo. It is hypothesized that participants consuming Actazin or Livaux will respond more than participants consuming the control formula. It is hypothesized that participants consuming Actazin or Livaux will have a favorable microbiome change than placebo.
