What's A2 protein milk?

A natural protein in milk that's easy on digestion.

Ordinary cows’ milk naturally contains a mix of both A1 and A2 proteins. A2 protein Milk comes from cows that naturally produce only the A2 protein and no A1 protein. Body of research suggests that a2 protein milk helps people avoid discomfort and overcome lactose intolerance.

Only A2 Protein Milk

A1/A2 β-casein

A2 milk is cow’s milk that mostly lacks a form of β-casein protein called A1 and instead has mostly the A2 form.

The Difference

A1 and A2 β-casein are genetic varients of the beta-casein milk protein that differ by one amino acid. 

The Determinant

A genetic test of the cow determines whether a cow produces A2 or A1 type protein in its milk. 

Devil in the Milk

A1 β-casein may be a risk factor for heart disease in adults, and also in the progression of type-1 diabetes in children.


moolrasa pure A2 protein milk comes from pure native (Gir) breeds that are genetically tested to produce only A2 milk and no trace of A1. 


The A1 - A2 debate is real and not a marketing strategy. Rather it's the established dairy brands that are lobbying against A2 protein milk. 

Genetic mutation in cows many years ago created an aberrant A1 protein in some European cows, called A1 cows to set them aside from all other cows, which are called A2. As a result, the milk from these cows has been linked to a host of maladies, including Type 1 diabetes, autism and heart disease. 

Though all cows in India were naturally A2, rampant cross breeding of the indigenous breeds with the European breeds has put our health at risk.
