What researchers measure

Primary outcomes

  1. Percentage of Participants with a Positive Response to the Product Satisfaction Question

    Participants will be asked to consider how they felt in the past week in regard to their gastrointestinal well-being and symptoms of abdominal discomfort or pain, bloating, or distension, gas, and altered bowel habit, and to respond to the following overall product satisfaction question: "Compared to the way you felt before beginning the supplement, how strongly do you feel you have had improvement of your overall gastrointestinal well-being?". Responses will be assessed on a Likert 6-point scale. Potential responses will include 1=strongly agree, 2=disagree, 3=slightly disagree, 4=slightly agree, 5=agree, and 6=strongly agree. The percentage of participants with the response of 4=slightly agree, 5=agree, and 6=strongly agree will be reported.

    Time frame: Day 42 (End of Study [EOS] Visit)

Secondary outcomes

  1. Measures of Quality of Life Using the Irritable Bowel Syndrome Quality of Life (IBS-QOL) Questionnaire

    To assess quality of life prior to and post-treatment, participants will be asked to rate 34 quality of life questions from the sub-categories of dysphoria, interference with activity, body image, health worry, food avoidance, social reaction, sexual, and relationship, using the following scale: 1=Not at all; 2=Slightly, 3=Moderately; 4=Quite a bit; 5=Extremely. Lower scores=better IBS-related QoL.

    Time frame: Baseline up to Day 42 (EOS Visit)

  2. Severity of Diarrhea, Constipation, Straining, Urgency, Abdominal Pain/Discomfort, Bloating, and Distention as Measured by the Gastrointestinal (GI) Health Symptom Questionnaire

    Participants will be asked to rate GI symptoms of diarrhea, constipation, straining (difficulty) to move bowels, urgency to move bowels (need to rush to the bathroom to avoid an accident), abdominal pain/discomfort, bloating, and distention (abdominal swelling), using a severity scale where 0 represents "none" and 10 represents "severe".

    Time frame: Baseline up to Day 42 (EOS Visit)

  3. Frequency of GI Symptoms as Measured by the GI Health Symptom Questionnaire

    Participants will be asked to report the number of days per week (that is, never, 1-2 days, 3-4 days, 5-6 days, or 7 days) they experienced the symptoms of diarrhea, constipation, straining (difficulty) to move their bowels, urgency to move their bowels (need to rush to the bathroom to avoid an accident), abdominal pain/discomfort, bloating, distention (abdominal swelling), ability to fully empty bowels, and excessive passage of gas.

    Time frame: Baseline up to Day 42 (EOS Visit)

  4. Satisfaction with Ability to Fully Empty Bowels as Measured by the GI Health Symptom Questionnaire

    Participants will be asked to rate how satisfied they are with the ability to fully empty their bowels on a scale where 0 represents "not satisfied" and 10 represents "very satisfied".

    Time frame: Baseline up to Day 42 (EOS Visit)

  5. Passage of Gas Symptoms as Measured by the GI Health Symptom Questionnaire

    Participants will be asked to rate their excessive passage of gas symptoms on the scale where 0 represents "never" and 10 represents "frequently".

    Time frame: Baseline up to Day 42 (EOS Visit)

  6. Satisfaction with Bowel Habits as Measured by the GI Health Symptom Questionnaire

    Participants will be asked to rate how satisfied they are with their bowel habits on a scale where 0 represents "not satisfied" and 10 represents "very satisfied".

    Time frame: Baseline up to Day 42 (EOS Visit)

  7. Overall Product Satisfaction Evaluation

    Participants will be asked to respond to the statement "Taking everything into consideration, would you say you are satisfied with this probiotic supplement, overall?" with a response of "Yes", "No", or "Do Not Know".

    Time frame: Day 30

  8. Change From Baseline in Intestinal Fatty-Acid Binding Protein (I-FABP) Levels (Intestinal Integrity Serum Marker) at Day 30

    Intestinal permeability assessments will be conducted through the evaluation of serum I-FABP levels in a blood sample collected from participants at Baseline and Day 30.

    Time frame: Day 30
