Is this trial a fit for you?
✓Likely a good fit
Healthy women aged 18–65 with BMI 18.5–29.9 kg/m2 who are not non-childbearing or who use acceptable contraception and have a negative pregnancy test at baseline.
✕Probably not a fit
Participants who do not experience a reduction in bloating or who have different gastrointestinal responses may not see a benefit.

What this trial studies
This interventional study compares Bloat to a placebo to see if it reduces postprandial bloating in healthy women. Participants will take one dose daily for 55 days and complete questionnaires about gas, bloating, and abdominal discomfort. The primary outcome is the change in bloating severity at 60 minutes after dosing from baseline. The trial collects self-reported symptoms to assess safety and effectiveness over time. Eligible participants are women aged 18–65 with standard BMI ranges who meet contraception requirements if applicable.
Why it matters
Potential benefit: If successful, participants may experience less post-meal bloating and abdominal discomfort when taking Bloat.
How similar studies have gone: Similar approaches have shown mixed results in reducing bloating, with some studies suggesting potential benefits and others showing no difference from placebo.
