Where does milk usually come from? Cows of course! And what kind of cow does NuManna powdered milk come from? A Happy Cow. Why are NuManna cows so Happy Because NuManna cows are not pumped full of Hormones. Unlike many other storable food companies all our powdered milk is Hormone-Free. And all our milk receives our proprietary bio-enhancement treatment and packaged correctly for long term storage before it is labeled NuManna Best.
