Bone Broth Powder

Bone broth is simmered bovine, chicken, or fish bones and connective tissue, often sold as a spray-dried powder. There are no RCTs on bone broth itself as a supplement — clinical claims for joint, skin, and gut health are extrapolated from collagen RCTs and amino acid mechanism studies, not from bone broth trials. Collagen content is variable (~10–30% by dry weight) and significantly lower than hydrolyzed collagen peptide supplements. A 13.5 g serving of bone broth powder typically delivers only 1.5–4 g of collagen, versus 10–20 g in a dedicated collagen peptide product — dose-for-dose, bone broth is a less efficient collagen source. Also contains glycine (~25% of collagen by weight), proline, glutamine, and trace minerals, but at doses well below therapeutic thresholds for most endpoints. Homemade broth varies enormously in composition; commercial powders are more consistent but rarely third-party tested for heavy metals.
