Is Our Milk A2A2?
First off, what does this mean?
When we say "A2A2," we're referring to the type of beta-casein protein found in milk. Beta-casein is one of the main proteins in dairy, and it comes in different genetic variants. The "A2A2" designation means the milk contains only the A2 variant of this protein. Some dairy breeds naturally produce milk with only A2 beta-casein, while others produce a mixture of A1 and A2 variants. This genetic difference is determined by the animal's DNA and is passed down through breeding.
For some people with dairy sensitivities (not allergies), A2A2 milk may be easier to digest.
For some people with dairy sensitivities (not allergies), A2A2 milk may be easier to digest. The difference between A1 and A2 beta-casein relates to how the protein breaks down during digestion. Some research suggests that the A1 variant may trigger digestive discomfort in certain individuals, while the A2 variant is gentler on the system. This is why A2A2 milk has gained attention among people looking for dairy options that work better for them. It's important to note that this applies to sensitivities rather than true dairy allergies, which involve a different immune response altogether.
After years of working toward this goal, our milking herd is getting close—84% A2A2 as of March 2026! Which means in a few short years, we should be at 100%.
As of March 2026, our milking herd is 84% A2A2.
We will keep our website updated as as this changes.
