Voted World's Cleanest Whey! - Raw Grass Fed Whey is 100% cold pressed from happy healthy pasture fed cows. Our jersey cows graze freely on lush, green pastures year round. These small-farm cows are not only healthier but we believe happier too! Their diet consists of a variety of wild grasses and clover - producing milk rich in omega-3s and CLAs. The result is a deliciously creamy whey protein that has the highest protein concentration among natural grass-fed whey powders.
