A1 vs A2 protein: What’s the Difference? | a2 Milk® USA

A1 vs. A2 protein: what’s the difference?

The main difference between ordinary and a2 Milk® lies within the milk’s protein. To better understand the protein, it’s helpful to first review the milk’s content.

All milk is made up of water and solids. The solid components within milk are:

  • Lactose (milk sugar)
  • Fat
  • Minerals
  • Protein

There are different types of protein in milk: whey and casein; the casein protein is what differs in ordinary milk vs. a2 Milk®.

There are two types of beta-casein: A1 and A2. Most cows’ milk available on grocery store shelves contains a combination of these A1 and A2 beta-casein proteins. a2 Milk® only contains the A2 beta-casein protein.
