All regular cow’s milk contains both the A1 and A2 Protein types, which make up around 30% of the total proteins in cow’s milk. However, some dairy milk, like A2 Protein Milk, is naturally free of the A1 Protein type and instead, contains only the A2 Protein.
You may ask “Why does this matter?” The Dietitians Association of Australia has this to say about A1 Protein free milk:
“Emerging research, which includes human studies, suggests that selected consumer groups who limit dairy intake owing to digestive discomfort may be able to consume A1 beta-casein free milk without adverse effect.”
