Important notice to customers — product packaging changesLearn More


From August 2018, customers will notice our rebranded food packaging start to appear on shelf in all major stockists.

  • CURRENT Packaging
  • new Packaging

We are excited to announce our new packaging will start to appear on shelf from August 2018. This transition to new packaging will occur over a number of months. During this time there will be a mix of current and new packaging on shelf.

There are no major changes to these products, in some instances there is a small name change or slight recipe improvement, see below for the full details.

Products purchased via the website will be delivered to customers in our old packaging until the end of October. From November, products ordered from the website will be delivered in the new packaging.

Please note, our Infant Formula packaging will not be rebranded until later in 2019.

What Are A2 Milk Proteins?

What are A2 Milk Proteins

Milk consists of two major proteins, casein and whey. Approximately one-third of the protein consists of beta-caseins, where there are two main types, known as A1 and A2 beta-casein.

The concentrations of A1 and A2 proteins in milk vary between different species of cattle and depend on the genetic makeup of the cow. Some cattle can produce either completely A1 beta-casein, a combination of both, or completely A2 beta-casein.

Consequently, milk containing a higher concentration of A1 protein is known as A1 milk or regular milk, while milk containing predominantly A2 protein is known as A2 beta-casein milk. The milk sourced for Beta Genica–8™ Toddler Milk is made exclusively from organic A2 beta-casein milk.




A1 and A2 proteins have different structures on the amino acid strand and because of the difference, these proteins are broken down and digested differently. Specifically, when the A1 protein is broken down, it releases a bioactive opioid peptide called beta casomorphin-7 (BCM-7), while the A2 beta-casein protein does not.

It is thought this difference means some people poorly tolerate milk. Studies in humans show that people who experience digestive discomfort symptoms drinking regular cow’s milk, may be able to consume milk containing only the A2 beta-casein protein without adverse effects. A recent study of children with self-reported mild to moderate discomfort following milk consumption showed replacing regular milk with A2 beta-casein milk reduced gastrointestinal symptoms.

Welcome to Bellamy’s Organic.

Please read this important message.

If you are able, breastfeeding is best, as it provides the ideal nutrition for babies and has other important health benefits too. Health Professionals are well placed to provide appropriate feeding advice and support. A healthy diet during pregnancy and whilst breastfeeding is important.

Introducing infant formula either partially or exclusively, may reduce the supply of breast milk. Once reduced, it is difficult to re-establish. Social and financial implications, such as preparation requirements and cost of formula until 12 months, should be considered. When using infant formula, always follow the instructions for use carefully, unnecessary or improper use may make your baby unwell.
