Casein is the most important group of proteins present in milk, making up round 80% of the full protein content material. There are numerous forms of casein in milk, and beta-casein is the second most typical one, which exists in at the very least 13 totally different variations.
Let’s take a fast dive into A1 and A2 milk.

Well being Advantages of A2 Milk
Widespread digestive signs like fuel, bloating, and diarrhea following dairy consumption are sometimes linked to lactose intolerance. Nonetheless, some researchers suggest that BCM-7, not lactose, might be answerable for related signs in sure people.
A examine on Chinese language adults with milk intolerance revealed that common milk (containing A1 and A2 proteins) induced extra abdomen ache and altered bowel actions, whereas A2-only milk didn’t set off such signs.
