Holle A2 Organic Growing-up Milk 3 is suitable from 12 months of age until the end of the third year as part of a mixed diet of bottle feeds and weaning. Holle A2 Organic Growing-up Milk 3 is sourced from specially selected cows which produce only A2 beta-casein protein. Today\'s standard cows\' milk contains two main types of beta-casein proteins. The structure of the beta-caseins in A1 and A2 milk only varies in one place and is caused by the presence of different amino acids. This difference is crucial because, unlike A1 milk, no BCM7 (beta-casomorphin-7) is produced when A2 milk is digested. BCM7 is an end product of protein breakdown and is believed to have a variety of non-beneficial effects. Holle A2 milk is sourced from European organic farmers and all ingredients are strictly monitored, guaranteeing the highest possible level of safety.Gluten free, Dairy free.
