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.
What about heavy metals?
The mineral study also measured lead and cadmium and judged the risk low at the amounts found in its samples. That finding is reassuring for those samples, but it is not a batch certificate for an unrelated concentrated powder. 1
Why does the animal source matter?
The Verbraucherzentrale warns that collagen products can cause allergic reactions and intolerance, particularly when fish-derived collagen meets a fish allergy. Added ingredients can introduce their own risks. The full ingredient list matters when comparing a broth powder with a collagen blend. 2
