vitamin b12 supplement
B12 is the animal-origin vitamin with a metal heart — cobalt-built, plant-absent, and clinically real in gut disease, where vets inject what intestines stop absorbing.
Also appears on labels as: vitamin b12 · cyanocobalamin · vitamin b-12 supplement
What it is
Cobalamin, the only vitamin built around a metal atom (cobalt) and the one no plant makes — microbes and animal tissues are the supply, another quiet argument written into carnivore biology. The 'cyano-' in supplemental cyanocobalamin alarms label-readers occasionally: the cyanide group is a trace stabilizer, metabolized without consequence.
Why it's in pet food
Completeness — meat-rich recipes carry B12 naturally; supplementation guarantees it. The clinical story is the interesting half: chronic intestinal disease in dogs and especially cats depletes B12 to where food can't fix it, and cobalamin injections are standard, genuinely effective veterinary practice.
How Bowlmark scores it
Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.
Neutral. The takeaway points at the clinic, not the label: a pet with chronic GI disease may need its B12 measured and injected regardless of how complete the food is — absorption, not supply, is the broken link. The GI guide carries the fuller story.
For cats
Low cobalamin is common enough in feline chronic enteropathy that measuring it is routine — a bloodwork conversation, not a food-shopping one.
