NCT05614726

Brief Summary

This randomized, placebo-controlled, double-blind study will determine the effect of daily supplementation with a probiotic blend in 60 apparently healthy men and women recruited at a single investigational center in Northeast Ohio (i.e., The Center for Applied Health Sciences). Subjects will attend three study visits. During Visit 1, subjects will be screened for participation \[i.e., medical history, routine blood work, background baseline diet\]. During Visits 2 and 3 subjects will complete questionnaires that assess their gastrointestinal health (e.g., abdominal discomfort/bloating, constipation, regularity, stool consistency). Visits 2 and 3 will correspond to before (week 0) and after six weeks of supplementation, respectively, with the probiotic dietary supplement or placebo.

Outcome Measures

Primary Outcomes (4)

  • Flatulence (gas)

    Flatulence (gas) as measured by a 10 cm visual analogue scale, where higher values represent greater flatulence.

    Change from baseline to 6 weeks.

  • Gastro-intestinal bloating

    Gastro-intestinal bloating as measured by a 10 cm visual analogue scale, where higher values represent greater bloating.

    Change from baseline to 6 weeks.

  • Abdominal discomfort

    Abdominal discomfort as measured by a 10 cm visual analogue scale, where higher values represent greater discomfort.

    Change from baseline to 6 weeks.

  • Gastrointestinal Symptom Rating Scale (GSRS)

    Gastrointestinal problems as measured by the GSRS questionnaire, where higher values represent increased severity of gastrointestinal problems.

    Change from baseline to 6 weeks.

Secondary Outcomes (3)

  • Stool consistency

    Change from baseline to 6 weeks.

  • Stool regularity

    Change from baseline to 6 weeks.
