A1 vs A2 Dairy Explained

By Trillium Nutritional · · 4 min read

You have probably seen “A2 milk” in the grocery store. The difference comes down to one protein.

What beta-casein is

Beta-casein is one of the main proteins in milk. It comes in different forms, and the two most common are called A1 and A2.

Where A1 and A2 come from

Many common dairy cow breeds produce a mix of A1 and A2. Water buffalo, goats, sheep, and some heritage cow breeds produce A2.

Some people say A2 dairy sits better with them. Research is ongoing, and everyone is different.

Buffalo colostrum is naturally A2

Because water buffalo produce A2 beta-casein, Trillium colostrum is naturally A2. Nothing is filtered or processed out to get there.
