Bone broth has become popular in human foods and more recently in the pet food aisle. There are some near-medicinal claims related to companion animals which include benefits to joint health and care for osteoarthritis. These are purported to be due to a list of compounds ranging from hydrolyzed cartilage, collagen and gelatin to chondroitin, glucosamine and hyaluronic acid. Bone broth has also been claimed to help “detoxify the liver” due to its high concentration of glycine and that it prevents “leaky gut” and even provides relief from food and environmental allergies.
