- Horizon Organic Grassfed Whole Vitamin D Milk
We Believe Happy Cows Make the Best Grassfed Milk. At Horizon, our grassfed cows spend time in lush pastures, where they graze freely. With access to shade, shelter, fresh air and clean drinking water—we believe our cows live happier lives. It’s no surprise our refreshingly creamy, organic grassfed whole vitamin Dmilk tastes so good.
