Could a Dual-Action supplement tame irritable bowel syndrome?
NCT ID NCT07716852
First seen Jul 21, 2026 · Last updated Jul 24, 2026 · Updated 3 times
Summary
This study tests whether a daily supplement called Enzymax DuoBiotics can ease symptoms of irritable bowel syndrome (IBS) in adults. The supplement combines digestive enzymes that break down food in the stomach with a probiotic and prebiotic that support gut bacteria in the intestines. Over 12 weeks, researchers will measure changes in symptom severity and quality of life in 120 participants, comparing the supplement to a placebo.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a dietary supplement containing digestive enzymes (lipase, protease, amylase, glucoamylase) and a probiotic (Lactobacillus plantarum) with prebiotic fiber (fructooligosaccharides)
- What this could lead to
- If it works, this supplement could offer a new option for managing IBS symptoms like bloating, pain, and irregular bowel habits.
- What could go wrong
- This is a small, early-stage trial with 120 people, and supplements often show limited benefit over placebo. Results may not apply to all IBS types.
