According to Ali Miller, R.D., L.D., CDE, “At this point, it is just syntax,” she told mindbodygreen. That being said, there are some things to know about the, admittedly nuanced, difference between the two terms. The benefits of bone broth are largely due to its collagen content. Two of the individual amino acids that make up collagen, glycine and glutamine, are what give it that extra kick to improve gut health, as they play a role in supporting the lining of the digestive tract. Bone broth also may lend benefits to hair, skin, and nail health, as collagen has independently been linked to those benefits. Many (non-bone) broth recipes will also lean more heavily on aromatics and a mirepoix for flavor, whereas a bone broth, and a good stock, will have more animal products. According to Miller, this usually includes “the full carcass plus feet for chicken stock (aka chicken bone broth) or knuckles and marrow bones for beef stock (aka beef bone broth).
