Tag: A2 cheese

Over thousands of years, a natural genetic mutation caused most dairy cow breeds to produce milk containing a mix of A1 and A2 beta-casein proteins, a mix now found in the vast majority of milk and cheese. However, a growing number of producers are now sourcing milk from cows that only produce the more ancient A2 protein, creating a distinct option for cheese lovers.

Originally, all cows produced milk containing only the A2 beta-casein protein, a genetic trait that changed over centuries. Today, A2 in cheese signifies it is made from milk containing this specific protein variant, often resulting in a product that may be easier on the stomach for some individuals.

Some studies suggest that up to 25% of people have digestive issues with dairy that are not caused by lactose intolerance, but rather a sensitivity to the A1 protein. This has led many to seek alternatives. So, **what cheese has A2 protein**? This article explores cheeses made from milk containing only the A2 beta-casein protein, which may offer a gentler option for sensitive stomachs.
