What is A2 Milk?

A2 milk refers to milk that contains only the A2 beta-casein protein variant, which is believed to be more easily digestible for many people. Most conventional milk contains a mix of A1 and A2 beta-casein proteins, but A2 milk is sourced from cows that naturally produce only the A2 variant. This difference is significant because some studies suggest that A1 beta-casein may contribute to digestive discomfort in certain individuals.

How is A2 Milk Different?

A2 milk contains only the A2 beta-casein protein.
It is believed to be gentler on the digestive system compared to conventional milk.
Some people with lactose intolerance or dairy sensitivities report fewer symptoms when consuming A2 milk.

Research has shown that A1 beta-casein may trigger the release of certain peptides during digestion, which could lead to gastrointestinal issues for some individuals. A2 milk eliminates this potential trigger, making it a preferred choice for those seeking a more digestible dairy option.
