Could probiotics ease lactose intolerance? small study investigates
NCT ID NCT07652827
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a daily probiotic capsule containing two bacterial strains could reduce gastrointestinal symptoms like bloating, gas, and cramps in adults with lactose intolerance and methanogenic intestinal overgrowth. Twenty-two adults took either the probiotic or a placebo for 12 weeks. The goal was to see if the probiotic could improve symptoms and breath test results.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Probiotic formulation (Lacticaseibacillus rhamnosus and Limosilactobacillus fermentum)
What this could lead to
If it works, this could point toward a probiotic supplement to reduce bloating, gas, and other digestive discomfort in people with lactose intolerance.
What could go wrong
This was a very small pilot study with only 22 participants, so results may not apply to everyone. The probiotic may not work better than a placebo, and more research is needed.
