Which milk is best? new study compares A2, regular, and oat drinks
NCT ID NCT07436260
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how drinking different types of milk—A2 milk, regular milk, and oat drink—affects bone health, heart health, and immune function in healthy adults aged 30 to 60. Participants will drink 500 ml of one of these beverages daily for 12 weeks. The goal is to see if A2 milk, which lacks a certain protein fragment, offers unique health benefits compared to regular milk or plant-based alternatives.
