I love this bone collagen. I feel I am getting in this convenient and economical powder what would take me more expense and time to prepare beef bones for broth. I trust the quality of Great Lakes products from my own experience and from recommendations of Dr. Paul Saladino, CarnivoreMD. He used to use Great Lakes collagen, but now I believe he makes his own bone broth. But if Great Lakes was good enough for Dr. Saladino, it's good enough for me!
