I spent a short stint in Australia around 2017 and accidentally started buying A2 milk! I thought it was just an Australian Brand. My flatmate then asked me about my milk digestion issues and I was so confused?! But A2 milk wouldn't make it to the US for years! I actually made a YouTube video all about A2 milk when I first started my channel https://www.youtube.com/watch?v=T7bJH6jobjk
