A2 Milk
Milk from indigenous Indian cow breeds (Gir, Sahiwal) containing only the A2 beta-casein protein.
A2 milk is produced by indigenous Bos indicus cattle breeds, such as Gir, Sahiwal, Red Sindhi and Tharparkar, whose milk carries only the A2 variant of beta-casein protein. Holstein, Jersey and the crossbreds most Indian dairies keep commonly carry the A1 variant. The two differ by one amino acid, which changes how the protein breaks down in digestion: A1 can release a peptide called BCM-7, and A2 does not. Research on whether that matters for human health is ongoing and mixed, and Anvayapure makes no health claims for A2 milk or ghee. Ghee is almost entirely fat, so very little of either protein survives into the jar. What an A2 label reliably tells you is the breed the milk came from.
