This unique formula is sourced from grass-fed, pasture-raised cows in Argentina and Brazil. The cattle we select come from local farmers far from Buenos Aires who nurture only pasture-raised cattle. Rigorous testing by outside laboratories is performed to ensure purity. This formula is easy to use and is nearly flavorless and odorless. Our cold liquid soluble formulation does not clump or congeal so you can enjoy the benefits of our formula in your favorite cold or warm beverage. Because it can be mixed into hot or cold, you can mix this formula in your favorite drinks, smoothies, cereals, oatmeal, or any other foods that you regularly enjoy.
