Key information

About this study

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 cardiac dysfunction, liver or kidney disease may be excluded. 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 6 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.

  • NYHA Class III or IV congestive heart failure, atrial fibrillation, uncontrolled arrhythmias, cirrhosis, end-stage liver disease, stage 3b or 4 chronic kidney disease, or kidney failure

Primary outcomes

  1. Lower GI Collective

    Time frame: 7 weeks

    Difference between rates of change over time in lower GI score as assessed by a composite of PROMIS Gas and Bloating 13A, Diarrhea 6A, and Constipation 9A (scale 10-134; where the higher scores correspond to worse lower GI health)

Secondary outcomes

  1. Change in feelings of anxiety

    Time frame: 7 weeks

    Change in feelings of anxiety: Difference between rates of change over time in feelings of anxiety score as assessed by PROMIS Anxiety 8A (scale 8-40; with higher scores corresponding to more severe anxiety)

  2. Change in mood (emotional distress-depression)

    Time frame: 7 weeks

    Change in mood (emotional distress-depression): Difference in rates of change over time in emotional distress score as assessed by PROMIS Emotional Distress- Depression 8A (scale 8-40; with higher scores corresponding to greater levels of emotional distress)

  3. Change in GI-related Quality of Life (QOL)

    Time frame: 7 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)

Other outcomes

  1. Minimal clinically important difference (MCID) in lower GI health

    Time frame: 7 weeks

    Minimal clinically important difference (MCID) in Gas and Bloating: Likelihood of experiencing minimal clinically important difference in lower GI score as assessed by a composite of PROMIS Gas and Bloating 13A, Diarrhea 6A, and Constipation 9A (scale 10-134; where the higher scores correspond to worse lower GI health)

  2. Minimal clinically important difference (MCID) in feelings of anxiety

    Time frame: 7 weeks

    Minimal clinically important difference (MCID) in feelings of anxiety: Likelihood of experiencing minimal clinically important difference in feelings of anxiety score as assessed by PROMIS Anxiety 8A (scale 8-40; with higher scores corresponding to more severe anxiety)

  3. Minimal clinically important difference (MCID) in mood (emotional distress-depression)

    Time frame: 7 weeks

    Minimal clinically important difference (MCID) in mood (emotional distress-depression): Likelihood of experiencing minimal clinically important difference in mood score as assessed by PROMIS Emotional Distress- Depression 8A (scale 8-40; with higher scores corresponding to greater levels of emotional distress)

  4. Minimal clinically important difference (MCID) in GI-related QOL

    Time frame: 7 weeks

    Minimal clinically important difference (MCID) in GI-related QOL: Likelihood of experiencing minimal clinically important difference in GI-related QOL score as assessed by Digestion-associated Quality of Life Questionnaire (scale 0-9; where the higher scores correspond to worse GI-related QOL)
