"Cooked marrow from the interior of animal bones."
Raw bone marrow is dense in fat and calories with some minerals and collagen, but it is not a meaningful protein source the way muscle meat is — cooking it doesn't change that, it just makes it shelf-stable and safe to include. The marketing ("real bone marrow!") tends to overstate its nutritional weight in a treat; it's a flavor and richness ingredient more than a nutrition one. Score: 5/10.
A real but unresolved concern: often an ongoing FDA/AAFCO research question (like the grain-free/DCM investigation), a common allergen, or a vague-but-not-alarming label claim. -2.5 pts deducted.
