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 |

A product code is a series of numbers and letters printed on the outer package of each product that a manufacturer produces to provide information about when the product was made.
As part of the product code, products manufactured by The IAMS™ Company include a 'Best Used By' date, or the date at which the product is no longer considered fresh and should no longer be sold. This date is expressed in “ddmmyy” and “ddmmmyy” formats (line 1 below).
The second line represents company internal information for use in traceability and inventory control (line 2).
Depending upon the production line, pouch products might have code date information in a single or double line.
By recognizing and understanding these codes, customers can make sure they are receiving a fresh product.
Shelf life is the duration, measured in months, during which a product that is stored properly maintains its freshness. This means that if a product has a 16-month shelf life, it is fresh for up to 16 months from the date of manufacture.
The shelf life for our dry dog and cat foods is 16 months. All canned and pouch formulas have a shelf life of 24 months. Biscuits have a 12-month shelf life, and sauce formulas have a 16-month shelf life.
Unopened dry products are best stored off of the floor in a cool, dry place. Open bags of food should be stored in a clean, dry container with a tight seal. Dry products also might be frozen without loss of nutrients.
Opened wet products are best kept refrigerated in tightly sealed containers for no more than three days after the can has been opened. Wet products should not be frozen in unopened cans or pouches. However, wet foods can be frozen if removed from the container, packed in freezer containers and frozen immediately.
