In my understanding A2 and A1 (normal) milk are exactly the same, except for a slightly different casein (protein) molecule. Apparently the A1 molecule in normal milk is the product of a natural mutation which is present in most modern commercial milk cows, and is blamed for various health problems, including an opiate like effect in susceptible people.

The sugar and fat etc should be the same as for any other milk, ie lactose and saturated animal fat.

Is there anyone who drinks A2 milk on the forum?  I am trying it to see if I can tolerate it as normal dairy gives me migraines.  I also cannot tolerate the lactose but have discovered lacteese tablets which elleviates that problem.  Crossing my fingers the A2 will work for me.  I do wonder though why the sugar content is what it is.  I know lactose makes up 4.7g per 100ml so that accounts for some of it.  Where is the other 0.3 from???? Here is the nutrition panel.  Ingredients lists only milk.
