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.
