But there are two different kinds of casein: A1 and A2. A1 and A2 beta-casein are milk proteins found in cow's milk. Depending on the cow breed and genetic origin, a cow can produce A1 milk, A2 milk or both. The composition of A1 casein makes it susceptible to break down during digestion, causing our adverse effects to dairy products. A1 milk products can contribute to inflammation, leaky gut, hormone imbalance, compromised blood sugar levels, and even heart issues. A2 casein has a slightly different composition meaning it does not break down when digested. This means the health risks that are seen in A1 casein are generally not found in A2 casein.
Cow Breeds That Produce A1 Milk
Cow Breeds That Produce A2 Milk
Pure-bred Jersey cows, like the ones raised on High Lawn Farm, produce A2 milk. This means that their products (including ghee, butter, milk and cheeses) are safe to consume for people with a dairy sensitivity. We have been a fan of High Lawn Farm's products for a while now because of their creamy texture and superior taste. We are excited to now carry both High Lawn Farm's ghee and lightly salted butter. Whether you add it to your Bulletproof coffee or spread it on gluten-free toast, we encourage you to try Jersey cow milk for yourself!
