NCT07516587

Brief Summary

The goal of this crossover clinical trial is to evaluate the efficacy and safety of Bloat Gummies on postprandial bloating and related gastrointestinal discomfort in healthy adults with recurrent bloating. The main question it aims to answer is whether Bloat gummies reduce post-meal bloating, gas, or abdominal pain (stomach) discomfort. Participants will be asked to consume one dose of Bloat or Placebo after 2 test meals and answer questionnaires on gas, bloating and abdominal distension.

Outcome Measures

Primary Outcomes (1)

  • Mean change in bloating severity from pre-dose to t = 60 minutes post-dose as, comparing active product vs. placebo.

    Bloating severity assessed by Bloating Likert Scale of 0 to 4, with 0 being "no symptoms" and 4 being "severe symptoms."

    Evaluated from pre-dose to 60 minutes post-dose

Secondary Outcomes (5)

  • Mean change in bloating severity from pre-dose to t = 30 minutes post-dose, comparing active product vs placebo.

    Evaluated from pre-dose to 30 minutes post-dose

  • Mean change in gas severity from pre-dose to t = 30 and 60 minutes post-dose, comparing active product vs. placebo.

    Evaluated from pre-dose to 30 and 60 minutes post-dose.

  • Mean change in abdominal discomfort severity from pre-dose to t = 30 and 60 minutes post-dose, comparing active product vs. placebo.

    Evaluated from pre-dose to 30 and 60 minutes post-dose.

  • Mean change in waist circumference from pre-dose to t = 30 and t = 60 minutes post-dose, comparing active product vs. placebo.

    Evaluated from pre-dose to 30 and 60 minutes post-dose.

  • Proportion of participants demonstrating a reduction in waist circumference.

    Evaluated at 30 minutes, 60 minutes or both timepoints post-dose.
