Casein comprises approximately 80% of the total protein in milk, the balance is known as whey.
There are two main types of beta-casein in milk, scientists have named them A1 and A2. These protein types, based on the cow's genetics, differ by only one amino acid. This difference may be responsible for the different manner in which these proteins are processed in our digestion.
A2 is recognised as being the original or ancestor beta-casein gene in dairy cattle. However, due to the years devoted to breeding cows to produce more milk and creamier milk, the A2 original, ancestral genetics was severely diminished and the A1 genetics became more dominant amongst the milk producing cows.
As best we can determine, A1 developed following a genetic mutation in European dairy herds several thousands of years ago.
Beta-casein is critical for the transport of essential minerals and nutrients required for healthy growth and development.
The milk powder in a2PLATINUM® contains only the naturally occurring A2 type of the beta-casein protein, which makes it gentle on tiny tummies and sets it apart from other infant formula and Toddler Milk Drinks that also have the A1 protein.

Don’t Drink A1 Milk !! is an expose’ of the potential health hazards of drinking Type A1 cow’s milk. We now know that Type A1 cow’s milk genetically differs from the original A2 milk, and can generate the casomorphin peptide, BCM-7. The BCM-7 molecule can attach itself to the insulin-producing beta cells in the pancreas, prompting an autoimmune destruction of the beta cells, leading to diabetes. It is a strong oxidant, and can oxidize LDL cholesterol, contributing to plague build-up in the arteries. It is also a powerful morphine-like opiate, and can pass through the blood-brain barrier, promoting neurological disorders such as schizophrenia and autism.
Governments and regulatory agencies claim that the BCM-7 hypothesis is not ‘proven’ and that no risk assessment or protective action is warranted. The dairy farmers in New Zealand, where the research originated, are converting their herds to A2-only producers.
We may have at our fingertips a key to eliminating a significant cause of chronic disease and the opportunity to uplift our human health to an even higher level.
