About this study

Official title: A Randomized, Triple-blind, Placebo-controlled, Cross-over Study to Evaluate Acute and Short-term Efficacy of Digest Gold on Postprandial Abdominal Distension and Subjective Bloating in Healthy Adults

The goal of this clinical trial is to investigate the acute and short-term efficacy of Digest Gold on postprandial abdominal distension and subjective bloating in healthy adults. The main question it aims to answer is what is the difference between Digest Gold and placebo in time-to-relief of subjective bloating (time = 0 -120 minutes postprandial), as assessed by the bloating Likert scale?Researchers will compare Digest Gold to a placebo to see its effects on postprandial abdominal distension and bloating. Participants will:

  • Consume Digest Gold and a placebo.
  • Have height, weight, and waist circumference measured.
  • Have blood pressure and heart rate measured.
  • Provide blood samples.
  • Provide a fecal sample.
  • Complete study questionnaires assessing gastrointestinal symptoms and subjective bloating.
  • Record their daily food intake.
  • Complete a breath test to assess gastrointestinal parameters.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Digest GoldDietary supplement

    At Visit 1 (Day 1 of Period 1) and Visit 3 (Day 1 of Period 2), study staff will provide participants with one capsule of study product with water to be consumed with the first bite of the standardized meal. Starting on Day 2 of Period 1, participants will be instructed to take one capsule three times a day with food (at the beginning of breakfast, lunch, and dinner) until Day 6 of Period 1. After a minimum 10-day wash out, participants will return to the study site and will be provided with one capsule of study product to be taken with water at the first bite of the standardized meal. Participants will be instructed to resume daily consumption of the alternate study product (one capsule three times a day with food (at the beginning of breakfast, lunch, and dinner)) from Day 2 until Day 6 of Period 2.

  • PlaceboDietary supplement

A four-point Likert scale (absent - 0, mild - 1, moderate - 2, or severe - 3) will be used to measure gas and bloating. A higher score means more severe bloating.

    Measured: Day 1

Secondary outcomes (18)

Questions about this trial

What is this clinical trial studying?

A study testing Digest Gold in people with Postprandial Abdominal Distension and Bloating, run by Enzymedica.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 16 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 23 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Erin Lewis (+248 1-226-242-4551, elewis@kgkscience.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The difference between Digest Gold and placebo in time-to-relief of subjective bloating (time = 0 - 120 minutes postprandial) (time frame: Day 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Sep 2026; AzTrials last refreshed its copy on 29 Oct 2026.
