Read the detailed description
This is a randomized, double-blind, placebo-controlled study conducted with adult participants, residing in the United States. Eligible participants will (1) have the opportunity for meaningful improvement (at least 30%) in their primary health outcome, and (2) express acceptance in taking a product and not knowing its formulation until the end of the study.
Participants that report a known contraindication or with well-established, significant safety concerns due to illness will be excluded. Heavy drinkers and those who report they are pregnant, trying to become pregnant, or breastfeeding will be excluded. Participants that report taking medications with a known contraindication or with well-established, significant safety concerns will be excluded. Self-reported data are collected electronically from eligible participants for 5 weeks. Participant reports of health indicators will be collected at enrollment and throughout the active period of study product usage. All study assessments will be electronic; there are no in-person visits or assessments for this real-world evidence study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Constipation
Change in Constipation: Difference between rates of change over time in constipation score as assessed by PROMIS Constipation 9A (scale 5-45; where the higher scores correspond to worse constipation)
Measured: 5 weeks
Secondary outcomes (3)

Measured: 5 weeks
Change in GI-related Quality of Life (QOL)
Change in GI-related Quality of Life (QOL): Difference between rates of change over time in GI-related QOL as assessed by Digestion-associated Quality of Life Questionnaire (scale 0-9; where the higher scores correspond to worse GI-related quality of life)
Measured: 5 weeks
Change in the severity of gastrointestinal symptoms
Change in the severity of gastrointestinal symptoms: Difference between rates of change over time in gastrointestinal symptoms score as assessed by GSRS (scale 7-105; with higher scores equaling greater severity)
Measured: 5 weeks

- Model description
- Participants who complete all enrollment requirements will be stratified before randomization. Stratification will be based on three factors: sex assigned at birth (female or non-female), age (21-44, 45-64, or 65+ years), and health outcome score (categorized according to published PROMIS scoring guidelines). Participants will then be randomized sequentially within each stratum to one of the study groups to ensure balanced allocation across treatment arms across all stratification factors. Following randomization, participants will receive their assigned study product along with written instructions describing product use and study procedures.
