Your dog needs antioxidants to help promote a healthy immune system. This is why every IAMS™ dog formula contains optimal levels of these nutrients.
Antioxidants are important naturally occurring nutrients that help maintain your dog’s health by slowing the destructive oxidative process of cellular molecules. IAMS research is advancing antioxidant nutrients for senior dogs — and the benefit is improved immune function.
Discover how the antioxidants in IAMS products can benefit your dog’s health in a number of ways.
Antioxidants are found naturally in the body and in plants such as fruits and vegetables. Common antioxidants include vitamin A, vitamin C, vitamin E and certain compounds called carotenoids (like lutein and beta-carotene). When antioxidants are part of a dog’s complete diet, they can provide the following benefits:
As cells function normally in the body, they produce damaged molecules called free radicals. These free radicals are highly unstable and steal components from other cellular molecules, such as fat, protein or DNA, thereby spreading the damage.
This damage continues in a chain reaction, and entire cells soon become damaged and die. This process is called peroxidation. Peroxidation is useful because it helps the body destroy cells that have outlived their usefulness, and it kills germs and parasites. However, when left unchecked, peroxidation also destroys or damages healthy cells.
Antioxidants help prevent widespread cellular destruction by willingly donating components to stabilize free radicals. More importantly, antioxidants return to the surface of the cell to stabilize rather than damage other cellular components.
When there are not enough antioxidants to hold peroxidation in check, free radicals begin damaging healthy cells, which can lead to problems. For example, free radical damage to immune cells can lead to an increased risk of infections.
Recent research has examined the benefits of certain antioxidants on the immune response of dogs, and the results of these studies indicated that antioxidants are important in helping dogs maintain a healthy immune system.
IAMS adult and puppy formulas contain optimal levels of antioxidants such as:
| Antioxidant | Source | Function |
|---|---|---|
| Vitamin E | Plant oil extract and tocopherols | Optimizes immune system’s T-cell activation |
| Beta-carotene | Vitamin premix, corn meal, chicken by-product meal and chicken fat | Optimizes types of cell present in the blood, increases antibody levels in the blood |
Nutrients are divided into subcategories: protein, carbohydrates, fats, vitamins and minerals, and water.
Common dog-food protein sources include meat, poultry, fish, and some plant ingredients such as corn gluten and soybean meal.
Protein is best known for supplying amino acids, or protein subunits, to build hair, skin, nails, muscles, tendons, ligaments, and cartilage. It also plays a main role in hormone production.
Dogs, best fed as carnivores, require essential amino acids, that are not all found in the correct balance in single plant-protein sources such as soybean meal.
Common carbohydrate sources are plants and grains. Carbohydrates, also categorized as starches (sugars) and fibers, provide energy and bulk, respectively.
Starches are made up of various types of sugar, such as glucose or fructose. Through digestion, dogs can easily convert sugar into usable energy.
Fiber may or may not be fermented or broken down into short-chain fatty acids by bacteria in a dog's intestines. Highly fermentable fiber sources, such as vegetable gums, provide high amounts of short-chain fatty acids. Moderately fermentable fibers, such as beet pulp, provide short-chain fatty acids and bulk for moving waste. Slightly fermentable fibers, such as cellulose, provide mainly bulk for moving waste through the digestive tract and only a few short-chain fatty acids.
Fats are found in meats, poultry, fish, and plant oils, such as flax and vegetable oils. Fat, for all of its bad press, fulfills many vital body functions. Animal-cell membranes are made of fat. Fat also helps maintain body temperature, control inflammation, and more. Fat is the primary form of stored energy in the body, providing twice as much energy as carbohydrates or proteins.
Fats also provide the important fat subunits, omega-6 and omega-3 fatty acids. Omega-6 fatty acids are essential for skin and coat maintenance and proper membrane structure. Omega-3 fatty acids have been shown to be important in blood clotting and decreasing inflammation.
Vitamins are responsible for promoting bone growth, blood clotting, energy production, and oxidant protection.
Vitamins A, D, E, and K require fat for absorption into the body, while vitamins such as the B-complex vitamins and vitamin C need water to be absorbed into the body.
Minerals provide skeletal support and aid in nerve transmission and muscle contractions.
