NCT ID NCT07540949
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether a daily capsule made from fermented fruits and vegetables (Rutazyme®) can improve body fat, waist size, and blood markers in adults with obesity. Forty participants will take either the supplement or a placebo for 12 weeks. Researchers will measure changes in body composition, blood sugar, and gut health.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Rutazyme® lemon fermented product (a dietary supplement made from fermented fruits and vegetables)
- What this could lead to
- If it works, this could point toward a simple, natural supplement to help manage obesity and metabolic syndrome.
- What could go wrong
- This is a small, early-stage trial with only 40 people. The supplement may show no benefit over placebo, and results may not apply to everyone with obesity.
