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 |

Providing your dog with a balanced diet of nutritious dog food will ensure they get adequate amounts of protein, fat and fiber. All three are essential to your dog’s health and happiness — and all three can be found in every IAMS™ product we produce. Learn more about how these three vital elements can support your dog’s whole-body health.

Protein Protein helps keep your dog’s muscles strong.
Protein helps keep your dog’s muscles strong. It also provides the amino acids necessary to build and repair proteins in their body. Many of these amino acids must be acquired through a dog’s diet.
Recipes contain animal-based proteins that provide the essential amino acids dogs need. Plus, we conduct special refining and quality assurance tests to ensure we only use high-quality, highly digestible protein sources for increased digestibility.

Fat gives your dog energy and helps nourish their skin and coat.
Fat provides energy. Your dog needs two types of fatty acids: omega-6 andomega-3 fatty acids. Omega-6 fatty acids are found in chicken fat and corn.Omega-3 fatty acids are found in ingredients such as canola, fish meal or oil, andflax. Both types help nourish and support your dog’s skin and coat.
Fiber and prebiotics help support your dog’s digestion.
IAMS™ dog food recipes feature a tailored blend of natural fiber from ingredients like beet pulp, as well as prebiotics to help support your dog’s digestion. Research has shown that moderately fermentable fiber, such as beet pulp, enhances intestinal health.
Feeding your dog a balanced diet that contains the right amounts of protein, fats and fiber is one of the most important ways you can care for and nourish them. To see the di!erence a healthy diet can make in your dog, feed them an IAMS recipe that’s tailored to their unique dietary needs, such as their size, age and breed. Are you ready to See the Wow?
