Milk from our grass–fed cows is naturally richer and can have advantages in the nutritional quality of the milk.

Milk production in the United Kingdom of Great Britain and Northern Ireland is primarily grass–based and this can have advantages for the nutritional quality of the milk.

The United Kingdom is one of only a few countries which utilises grass as the main component in our cows’ diet, and milk from pasture–based dairying can contain more of certain healthy nutrients. Milk from our grass–fed cows is naturally richer in the beneficial fatty acids CLA (conjugated linoleic acid) and omega–3s, and can have higher amounts of some vitamins, such as vitamin E.
