Answer:Bone broth protein supplements are produced by dehydrating bone broth (typically from chicken or beef bones) and can be a good source of protein and, in particular, collagen — the main protein found in bone. There is some evidence, that, like other types of protein, collagen may help to build muscle, and additionally, may help reduce joint pain and improve skin elasticity and wrinkles. However, most of the evidence for these uses are based on studies using collagen supplements, not bone broth. (See the Bone Broth Review for more information and our tests of products).
