Een klinische studie naar de veiligheid en effectiviteit van Bloat op gas en een opgeblazen gevoel bij gezonde vrouwen

25 september 2026 bijgewerkt door: Arrae

Een gerandomiseerde, dubbelblinde, placebo-gecontroleerde, parallelle klinische studie naar de veiligheid en werkzaamheid van Bloat bij gasvorming en een opgeblazen gevoel bij gezonde vrouwen

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.

Participants will continue taking one dose daily, with water after dinner, for a total of 55 days. Participants will be advised to take the product at least two hours before or two hours after regular medication.

Placebo-vergelijker: Placebo

Placebo is comprised of white rice flour

Participants will be instructed to take one dose (2 capsules) 30 minutes after consumption of the entire standardized meal with water during the screening/baseline clinic visit (Day 1). Participants will continue taking one dose daily, with water after dinner, for a total of 55 days.
