Rutazyme Lemon Fermented Product Capsules for Metabolic Function in Adults With Obesity
Taiwan40 participantsStarted 2026-03-16
Plain-language summary
This study evaluates whether a fruit- and vegetable-based fermented product (Rutazyme® lemon fermented product) taken as a capsule can improve metabolic health in adults with obesity. Forty adults aged 18-65 years with obesity (BMI ≥ 27 kg/m² and waist circumference \> 90 cm for men or \> 80 cm for women) will be randomly assigned to receive either a Rutazyme® lemon fermented product capsule (500 mg) or a placebo capsule once daily at bedtime for 12 weeks. Before supplementation, participants will complete a 2-week stabilization period during which they maintain their usual diet and physical activity.
Body composition and waist/hip measurements will be assessed during the study, and blood pressure will be monitored. Blood samples will be collected to evaluate metabolic and safety laboratory measures (e.g., lipids, glucose, insulin, inflammation markers, liver and kidney function), and stool samples will be collected to assess gut microbiota. Gut-brain axis biomarkers (GLP-1 and PYY) will be measured at multiple time points after capsule intake at baseline and at Week 12. The results will help determine the metabolic effects and safety of Rutazyme® lemon fermented product supplementation in adults with obesity.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
