Clinical trials: Lactose Intolerance
Lactose Intolerance, Adult Type
Comparing the Gastric Transit of Commercial Milk and A2 Milk
Cow's milk contains two types of β-casein: A1 and A2. The μ-opioid peptide BCM-7 is released from A1 but not from A2. BCM-7 is associated with slower gastrointestinal transit and hence increased gastrointestinal transit times.

Lactose Intolerance
