What is the difference between A1 and A2 milk?
Regular milk contains both A1 and A2 beta-casein, but A2 milk contains only A2 beta-casein. Some studies suggest that A1 beta-casein may be harmful and that A2 beta-casein is a safer choice. Thus, there is some public and scientific debate over these two types of milk.
What does A1 and A2 mean in milk?
A1 milk has A1 type of protein (casein) and A2 milk has A2 type of protein (casein). This is important because the way the milk is broken down and metabolised in the system is different. Due to the difference in availability, A1 milk is relatively cheaper and easier to find than A2 milk.
Which breeds have A2 milk?
