<<Disclaimer: Verify this information before applying it to your situation.>> For those who have lactose and soy problems looking for a GF cheese, this apparently will fill the bill. However, those that cannot tolerate casein, you are still out of luck. There were several replies of satisfaction with the product. They also make a cheddar, american and a parmesan, in addition to the mozzarella. Since I didn't know if I had problems with lactose or casein I tried a half slice. I don't think I will be finishing the package, so I now know casein is the problem. I join the GF group that is looking for a true dairy free/soy free cheese replacement. cbh
