A1 milk contains the A1 beta-casein protein, commonly found in Holstein, Friesian and Ayrshire breeds of cow. It can often be harder to digest for some.

A2 milk contains only the A2 beta-casein protein. It is often considered more easily digestible. It is from breeds of cow such as Jersey, Guernsey and some Indian native breeds.

While A1 milk can produce a peptide when digested called (beta-casomorphin) BCM-7, that may form, when digested in sensitive persons, any bloating or discomfort; then A2 milk produces no BCM-7.

A2 milk is a little creamier and richer in taste than A1 milk, which makes it a great choice for coffee and desserts.

When looking for A2 milk, make sure it says 100% A2. In India, a number of brands are now marketing and selling milk from native cow breeds as A2.

If you are experiencing some discomfort after drinking regular milk, try drinking A2 milk for 2-4 weeks & see if your symptoms improve.

Whether to drink A1 or A2 milk will depend on your digestion, taste, & health needs. Just listen to your body & your gut will always know!
