What is the Beef Protein Isolate Derived From?Updated a year ago

The beef protein isolate used in Within You's Steak Shakes and Total Carnivore Steak Shakes is derived from the fleshy bones, tendons, and ligaments of the animal and not from the hides, hooves, or other byproducts. While this protein does contain a large percentage of naturally occurring collagen, it also contains amino acids derived directly from the flesh of the animal.
