+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.

+Outcome measures

Primary outcomes

  • Change in Constipation [5 weeks]: 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)

Secondary outcomes

  • Change in Gas and Bloating [5 weeks]: Change in Gas and Bloating: Difference between rates of change over time in gas and bloating score as assessed by PROMIS Gas and Bloating 13A (scale 3-59; where the higher scores correspond to worse gas and bloating)
  • Change in GI-related Quality of Life (QOL) [5 weeks]: 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)
  • Change in the severity of gastrointestinal symptoms [5 weeks]: 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)

Other outcomes

  • Minimal clinically important difference (MCID) in Constipation [5 weeks]: Minimal clinically important difference (MCID) in Constipation: Likelihood of experiencing minimal clinically important difference in constipation, as measured by PROMIS Constipation 9A (scale 5-45; where the higher scores correspond to worse constipation)
  • Minimal clinically important difference (MCID) in Gas and Bloating [5 weeks]: Minimal clinically important difference (MCID) in Gas and Bloating: Likelihood of experiencing minimal clinically important difference in gas and bloating, as measured by PROMIS Gas and Bloating 13A (scale 3-59; where the higher scores correspond to worse gas and bloating)
  • Minimal clinically important difference (MCID) in GI-related Quality of Life (QOL) [5 weeks]: Minimal clinically important difference (MCID) in GI-related Quality of Life (QOL): Likelihood of experiencing minimal clinically important difference 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)
  • Change in Diarrhea [5 weeks]: Change in Diarrhea: Difference between rates of change over time in diarrhea score as assessed by PROMIS Diarrhea 6A (scale 2-30; where the higher scores correspond to worse diarrhea)
  • Minimal clinically important difference (MCID) in Diarrhea [5 weeks]: Minimal clinically important difference (MCID) in Diarrhea: Likelihood of experiencing minimal clinically important difference in diarrhea, as measured by PROMIS Diarrhea 6A scale (2-30; where the higher scores correspond to worse diarrhea)
  • Change in cognitive function [5 weeks]: Change in cognitive function: Difference in rates of change over time in cognitive function score as assessed by PROMIS Cognitive Function 4A (scale 4-20; where lower scores correspond to worse cognitive function)
  • Minimal clinically important difference (MCID) in cognitive function [5 weeks]: Minimal clinically important difference (MCID) in cognitive function: Likelihood of experiencing minimal clinically important difference in cognitive function score as assessed by PROMIS Cognitive Function 4A (scale 4-20; where lower scores correspond to worse cognitive function)
  • Minimal clinically important difference (MCID) in the severity of gastrointestinal symptoms [5 weeks]: Minimal clinically important difference (MCID) in the severity of gastrointestinal symptoms: Likelihood of experiencing minimal clinically important difference in gastrointestinal symptoms score as assessed by GSRS (scale 7-105; with higher scores equaling greater severity)
