A2 Milk

Milk contains two proteins, casein and whey. There are different types of casein and one of which is Beta-casein. A1 and A2 are the variants of it. Cows produced milk containing only A2 form of beta-casein. But these days, most of the milk available from the grocery store contains mostly A1 proteins. The only difference between the milk protein in A1 and A2 milk is only one amino acid – which influences on how our bodies digest the milk.
