Milk mystery: which type causes fewer gut woes?
NCT ID NCT05305391
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looked at how different types of milk—A2 milk and protein-hydrolysed lactose-free A1 milk—affect gut symptoms and inflammation in 37 adults who usually feel discomfort from regular milk. Participants drank each milk type for three days while taking either a lactase capsule or a placebo. The goal was to see if protein breakdown or lactose content makes milk easier to tolerate.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
milk (A2, protein-hydrolysed lactose-free A1) with lactase or placebo capsule
What this could lead to
If successful, this could help identify which milk components cause symptoms and inflammation, potentially guiding dietary choices for people with milk intolerance.
What could go wrong
This is a small, early-stage study with only 37 participants. Results may not apply to everyone with milk intolerance, and the findings are exploratory.
