Holle A2 organic milk formula contains a selected mix of whey protein and casein. Our organic A2 milk is sourced from specially selected cows that naturally produce only the A2 protein type and no A1.

Better Digestion With A2 Milk
Cow’s milk consists of two main types of protein: Casein and whey. Casein makes up about 80% of the protein structure. There are several different types of casein, A1 and A2 beta-casein being the two most common.

The body digests these two different, and A1 has been claimed to be more difficult to digest, leading to potentially more digestive discomfort. Most milk contains both types of casein.

Holle A2 milk is great because, like human breast milk or goat milk, it lacks A1 beta-casein protein and instead has mostly the A2 protein, which comes from specially selected cows that exclusively produce the A2 beta-casein protein.
