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.
