Since 2009, Orgain has been making clean nutritional products. Orgain Grass Fed Protein Shakes are the first ready-to-drink shake with 100% New Zealand-sourced protein-free from steroids, rBST, antibiotics and genetically modified ingredients. Why New Zealand-sourced protein? Its considered among the purest sources of protein in the world as New Zealand relies on a pasture-fed system for its grass-fed cows. Orgain products contain absolutely no preservatives, artificial sweeteners, colors or artificial flavors. Best part? They are incredibly delicious!
