Salmon is a marine and freshwater fish high in protein and long chain omega-3 fatty acids.

Mackerel is a food fish of the North Atlantic. We use the clean tissue of undecomposed whole mackerel and/or mackerel cuttings. There is currently no official AAFCO definition for mackerel.

Natura uses whole, high-quality mackerel, which are ground and added to the ingredient mix. Mackerel is an excellent single-source protein. It is also an excellent source of Omega 3 fatty acids, which play a vital role in the structures of cell membranes. Fatty acids support growth, help maintain healthy skin and hair, and affect the development of the nervous system, including the brain.

We're sorry no definition is currently available for this ingredient.

Carrageenan is a red seaweed extract used as a food stabilizer and thickener.

The particular type of seaweed that Carrageenan comes from is common in the Atlantic Ocean near Britain, Europe and North America. The seaweed is boiled to extract the carrageenan. It is a natural ingredient which Natura uses in the thickening and stabilizing of our canned foods.

Guar gum is derived from the ground endosperm of the guar plant. It is a gelatinous substance from the legume family that contains protein and polysaccharides. Guar gum is considered GRAS (generally recognized as safe).

Guar gum is used as an emulsifier, thickener, and stabilizer in foods.

L-ascorbyl-2-polyphosphate is a more stable form of vitamin C.

Vitamins are organic compounds that function as parts of enzyme systems essential for the transmission of energy and the regulation of metabolisms of the body. Minerals are inorganic substances essential for a host of vital processes within the body. AAFCO regulates minimum standard quantities of vitamins and minerals in levels that pets need to survive. All pet food manufacturers supplement their products with vitamins and minerals. Beyond meeting these minimum requirements, all Natura products contain a complete vitamin and mineral supplement program that helps pets to thrive, not just survive. The minerals Natura uses are chelated, providing three to ten times greater assimilation than common minerals. Our products also contain microorganism supplements, which are not required by the AAFCO minimums. Included in our foods are some of the following: Ascorbic Acid, Beta Carotene, Biotin, Calcium Carbonate, Calcium Iodate, Choline Chloride, Cobalt Carbonate, Cobalt Proteinate, Copper Proteinate, d-Calcium Pantothenate, Dicalcium Pantothenate, dl-Methionine, Iron Proteinate, Manganese Proteinate, Niacin, Potassium Chloride, Pyridoxine Hydrochloride, Riboflavin, Thiamine Mononitrate, Vitamin A Supplement, Vitamin B12 Supplement, Vitamin C Supplement (Sodium Ascorbate), Vitamin D3 Supplement, Vitamin E Supplement (Alpha Tocopherol), Zinc Proteinate Natura adds these important vitamins and minerals, in proper balance to its foods to ensure that your pet gets all the necessary nutrients for life and good health every day.

Phosphorus is a naturally occurring substance that is important in every cell in the body. The majority of phosphorus in the body is found in the bones. The potassium and sodium salt forms of phosphorus are called phosphates.

A highly fermentable fiber, Inulin has not only become widely recognized as a superior soluble fiber source, it has also been clinically proven to increase calcium absorption. Derived from chicory roots, Inulin becomes a specific foodstuff for the bacteria found in the intestinal tract.

A tasteless white polysaccharide found especially dissolved in the sap of the roots and rhizomes of composite plants.

A chemical compound, KCl, a colorless or white, cubic, crystalline compound that closely resembles common salt (sodium chloride). It is soluble in water, alcohol, and alkalies.

Potassium plays various roles in metabolism and body functions. It assists in the regulation of the acid-base balance and water balance in the blood and the body tissue. It assists in protein synthesis from amino acids and in carbohydrate metabolism.

Salt is a natural mineral, necessary for life and good health.

Salt provides several essential nutrients, such as sodium and chloride, as well as important trace minerals. The average sodium level in our food and treats is currently 0.9 g/Mcal, which is considered low by industry standards, but still supplies the nutrients your pet's body requires.

Choline chloride is a vitamin "like" essential nutrient.

It is necessary to nerve function and fat metabolism and can be manufactured in the body but not at a sufficient rate to meet health requirements.

Beta Carotene is a carotenoid derived from plants that can serve as a precursor to vitamin A in the dog but not the cat. Beta Carotene also has antioxidant properties that can be beneficial to both dogs and cats.

Although several different carotenoids are capable of providing vitamin A, Beta Carotene is the most plentiful in foods and has the highest biological activity. Meat and poultry do not contain carotenoids but can provide active vitamin A when included in the diet. Milk, liver, egg yolk, and carrots contain high amounts of Beta Carotene. Both dogs and cats readily absorb Beta Carotene, and studies have shown this carotenoid may have a function in cell-mediated and body immune responses in these species.
