Bone Broth Protein
Bone broth protein is a powder made from broth of simmered animal bones. It contains amino acids also found in collagen, such as glycine and proline.
Can a powder borrow the evidence for collagen?
The composition study compared prepared broths with reference collagen supplements. It did not validate every product sold as bone-broth protein. A meaningful comparison needs the actual protein and amino-acid amounts in the serving, rather than the word “broth” alone. 1
