What is the difference between A1 and A2 beta-casein?
The sole difference is that one of the 209 amino acids that make up the beta-casein proteins, a proline, occurs at position 67 in the chain of amino acids that make up the A2 beta-casein, while in A1 beta-casein, a histidine occurs at that position.

The clinical evidence regarding both dairy foods and dairy proteins (i.e., casein and whey protein) have shown promise for improving insulin secretion in individuals with T2DM.
What is difference between A1 and A2 milk?
Is there a difference between A1 and A2 beta-casein-containing milk?
Conclusions: These preliminary results suggest differences in gastrointestinal responses in some adult humans consuming milk containing beta-casein of either the A1 or the A2 beta-casein type, but require confirmation in a larger study of participants with perceived intolerance to ordinary A1 beta-casein-containing milk. Abdominal Pain / etiology*
Does A1 beta-casein cause digestive problems?
Growing evidence suggests that A1 beta-casein triggers adverse digestive symptoms in some people. Debate about the potential health effects of A1 and A2 milk is ongoing. Research suggests that A1 beta-casein causes adverse digestive symptoms in certain individuals.
Does A1 beta-casein protect against type 1 diabetes?
While some animal studies have found no difference between A1 and A2 beta-casein, others show A1 beta-casein to have either protective or adverse effects on type 1 diabetes (, , , ). So far, no clinical trials in humans have investigated the effect of A1 beta-casein on type 1 diabetes.
What are the different forms of beta-casein?
Beta-casein is the second most prevalent and exists in at least 13 different forms ( 1 ). The two most common forms are: A1 beta-casein. Milk from breeds of cows that originated in northern Europe is generally high in A1 beta-casein. These breeds include Holstein, Friesian, Ayrshire, and British Shorthorn.
