The main theory (and what the research is telling us!) is that A1 dairy is the problem when it comes to acne, NOT A2 dairy馃. Let鈥檚 talk about it: Cows originally produced only A2 casein, but a natural genetic mutation in European dairy herds thousands of years ago led to the A1 variant, primarily found in US/Canadian grown cows. Over time, selective breeding for higher milk yields spread this mutation, making A1 casein more common in modern dairy cows. Today, traditional breeds like Jersey cows
