What it is -Our grass-fed goats live on over 100 family-run farms in the Netherlands and supply the milk for our formula. Goat milk is made up of proteins called whey and casein, lactose, and some other very complex carbohydrates called oligosaccharides, and important fatty acids. What it does:- Goat milk more closely resembles breast milk and naturally contains a higher level of A2 -casein proteins that are different from the A1 -casein proteins in cow milk. A higher proportion of A2 proteins may provide comfort and prevent tummy troubles. The naturally occurring oligosaccharides in goat milk help support a healthy gut and immune system.
