The a2 Platinum® difference

The a2 Platinum® infant and toddler nutrition range is the first products where the beta-casein protein comes from cows specially selected to naturally produce the A2 beta-casein protein type and free from the A1 protein.

What is beta-casein?

There are two main groups of protein in cows’ milk: whey (around 20% of total protein) and casein (around 80% of total protein). Beta-casein is one of the 3 major casein proteins in milk and makes up about one-third of the total protein in milk. It transports essential minerals and nutrients such as calcium and phosphorous and provides important materials for building strong muscles, bones and other body tissues.

A1 and A2 beta-casein

There are two main types of beta-casein, called A1 and A2. These are produced by cows’ based on their genetic ability to produce one or the other. A2 is recognised as being the original or ancestor betacasein gene in dairy cattle. A1 beta-casein protein is a different protein that is now commonly found in cows’ milk. A1 developed following a genetic mutation in some European dairy herds several thousands of years ago.

A2 beta-casein and digestion

The A1 and A2 type proteins differ by only one amino acid. This difference in protein composition between the A1 and A2 type of beta-casein may affect how these proteins are broken down during digestion.
