Bone broth is a natural and versatile combination of multiple different nutrients. A long and gentle brew softens the bone material, releases collagen, and digests the nutritious bone marrow into the broth. Other active ingredients in bone broth include numerous different amino acids such as proline, glycine and glutamine, as well as chondroitin sulfate and glucosamine. Närokällan bone broth is made from the bones of Finnish reindeer that grazed in Lapland.
