Kirkland Signature Organic A2 Protein Whole Milk is ultra-pasteurized, Grade A whole milk containing only the A2 beta-casein protein variant. This USDA Organic certified milk comes from cows that naturally produce only A2 protein, which is the original beta-casein protein found in cow's milk before genetic mutation introduced the A1 variant. A2 milk may be easier to digest for people who experience discomfort with regular milk, as it does not produce the beta-casomorphin-7 (BCM-7) peptide during digestion that is associated with digestive issues. The product is fortified with Vitamin D and is an excellent source of calcium and a good source of protein.

This package contains four half-gallon (1.89L) cartons, providing convenient portioning for families. The milk is produced without rBST (recombinant bovine somatotropin) and is certified Kosher. It is certified organic by Oregon Tilth and produced in the USA by Costco Wholesale Corporation. The product must be kept refrigerated and is processed and packaged at the plant stamped above on the carton.
