The science behind beta-casein protein.
Approximately 30% of the protein found in cows’ milk is beta-casein protein. Ordinary cows’ milk contains a mix of both A1 and A2 beta-casein. The a2 Milk® is different because it is pure cows’ milk which is produced by cows that naturally produce milk containing only the A2 beta-casein protein type and no A1.
A1 beta-casein digests differently to A2 due to a slight difference in the amino acid sequence of the protein chain. During digestion A1 beta-casein releases beta-casomorphin-7 (BCM-7) whereas A2 beta-casein does not.

1) to highlight the extensive body of literature in the A1 beta-casein and beta-casomorphin related areas;
2) to stimulate interest amongst HCPs to obtain and review some of the relevant literature directly.
