A Clinical Trial to Investigate the Safety and Efficacy of Bloat on Postprandial Bloating and Its Effects Over Time in Healthy Women

The goal of this clinical trial is to investigate the safety and efficacy of Bloat on postprandial bloating in healthy women. The main question it aims to answer is what is the difference in change in bloating from pre-dose (postprandial) at t = 60 mins post-dose (postprandial) between Bloat and placebo, as assessed by the bloating numeric rating scale at screening/baseline. Participants will be asked to consume one dose of Bloat or Placebo for 55 days, and answer questionnaires on gas, bloating, and abdominal discomfort/distension.
