Full MoonPURE PROTEIN Air Dried Turkey Recipe

A calcium and phosphorus source that also keeps dry food from clumping. Both minerals are essential and their ratio matters for bone health. Routine and safe. For cats with kidney disease, phosphorus level is the number to watch, and the source is less important than the total.

Sodium and chloride, both essential, plus a palatability boost. Pets need less than people, and the minimum is set in the nutrient profiles the food is formulated to. Salt high on the list of a treat is a flavor choice; salt near the end of a complete food is nutrition. Ask your vet before choosing a low-sodium food for heart or kidney disease rather than reading labels alone.

A natural acid, the same one found in citrus, used alongside mixed tocopherols to slow fat from going rancid. It works by binding the trace metals that speed up oxidation. The amounts are tiny and it is one of the most benign preservatives available. A persistent claim links citric acid to bloat in dogs; it rests on one observational study with no mechanism behind it, and most veterinary nutritionists do not consider it supported.

A calcium source, the same compound as limestone or chalk. Meat is low in calcium and high in phosphorus, so foods add calcium to keep the two in balance, which matters for bone and for large-breed puppies in particular. Routine and safe. Not an allergen.

A copper source. Copper is essential in small amounts for blood, connective tissue and coat color. Some veterinary nutritionists have questioned whether modern dog foods carry more copper than dogs need, and a few breeds (Bedlington Terriers, Labradors among them) are prone to storing it in the liver. For most pets it is a routine additive. If your dog has a diagnosed liver condition, copper level is worth a vet conversation.

A manganese source. Manganese is needed in tiny amounts for bone, cartilage and enzyme function. Sulfate is the inorganic form; proteinate is the mineral bound to protein. The choice between them is a marketing distinction more than a health one for a healthy pet. Expected, safe, not an allergen.

Dogs and cats cannot make useful amounts of vitamin D from sunlight, so it has to be in the food. It governs calcium and bone health. It is also one of the few vitamins where too much is dangerous: excess vitamin D has caused pet food recalls. The amount is regulated and the presence of D3 on a label is expected. What matters is that the maker gets the dose right, which is a quality-control question, not an ingredient question.

Vitamin B1, essential for nerves and energy metabolism, and the vitamin most often behind cat food recalls. It is destroyed by heat and by some preservatives, so canned foods in particular must add it back. Cats are especially sensitive to running short. Its presence is expected; its absence from a cooked food would be a red flag.
