Antioxidants are naturally-occurring essential nutrients that help maintain your dog’s health by slowing the destructive oxidative process of cellular molecules. IAMS™ research has been focusing on 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 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 a 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 continues in a chain reaction, and causes cells to 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 stabilise free radicals. More importantly, antioxidants return to the surface of the cell to stabilise 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.
Antioxidants offer countless benefits to our furry friends. And it is imperative that their food is loaded with it. Want to know why? Read on.
Antioxidants are a must for dogs as they are exposed to significantly more toxins than humans. These antioxidants work like protective agents within the dog’s body, battling free radicals that cause symptoms and diseases like skin problems.
Furthermore, giving liver antioxidants for dogs will boost liver health and eliminate toxins from their body more efficiently. The liver will convert fat-soluble toxins into water-soluble toxins to easily flush them from your pet’s body through the GI tract and kidneys.
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:

Now that you know how dog food with antioxidants can benefit your dog, here’s a list of the best antioxidants for dogs:
You can find natural antioxidants for dogs in the following:
The antioxidant content of plant-based foods is high. Foods that are highest in antioxidants are fruits and vegetables as they are loaded with vitamins and beneficial in countless ways. Some examples of excellent sources of antioxidants are blueberries, strawberries, pears, red cabbages, and kale. Make sure to check which fruits and vegetables are safe for your dog to consume.
Give your dog the best vitamins you can, so your pooch stays healthy. It is crucial that dogs receive a supplement that is specifically designed for their life stage.
Look for dog food with antioxidants and nutrients that are bioactive and bioavailable so that these get absorbed properly into your dog’s body. Make sure that the supplement you choose has the ideal ratio of natural elements for your pet’s needs. That can be accomplished by looking for a combination of prebiotics, antioxidants, vitamins, and minerals.
For a healthy body from the inside, you can also feed your pooch IAMSTM Proactive HealthTM dog food. Find the products that are best for your dog by shopping based on your pet’s age.
Fruits, nuts, berries, and vegetables are common foods that act as good sources of antioxidants. Giving your dog an antioxidant-rich diet will aid in the battle against oxidative stress and reduce the risk of any illnesses.
Foods such as organ meats, mushrooms, eggs, bone broth, and raw goat milk speed up the healing of cuts, wounds, and other injuries in dogs.
The benefits of antioxidants for dogs are innumerable; however, it is always advisable to consult your veterinarian on the right dosage of antioxidants for your pet.
Three of the most important antioxidant vitamins are Vitamin E+C, selenium, and beta-carotene.
Antioxidant-rich foods for dogs help prevent damages due to free radicals. An adequate intake of antioxidants can help boost your dog’s immunity.

As dogs age, changes occur in the way their bodies function, so it makes sense that what they eat also might need to change. The following list of health issues might be more common in aging pets.
Decreased Immune System Function
Throughout a dog’s life, a process called peroxidation occurs. Peroxidation is a normal process that the body uses to destroy cells that outlive their usefulness and to kill germs, parasites, etc. This process, however, also can destroy or damage healthy cells. As your dog ages, the damage caused by peroxidation accumulates, which, in turn, increases the risk of certain problems, such as infections.
Antioxidants are naturally occurring nutrients that help maintain overall health by neutralizing the peroxidation process of cellular molecules. Some antioxidants, such as vitamin E, beta-carotene, and lutein, are naturally occurring nutrients.
Recent research sponsored by The IAMS™ Company found that dogs fed a diet rich in antioxidants such as vitamin E, lutein, or beta-carotene had improved immune responses and vaccine recognition. This might be especially important in senior dog care; IAMS research has found that as dogs age, immune responses can decrease.
More Frequent Intestinal Problems
Older dogs might have higher numbers of unfavorable bacteria and lower numbers of beneficial bacteria in their intestines, which can result in clinical signs of gastrointestinal problems (e.g., diarrhea).
Feeding a diet containing fructooligosaccharides (FOS), a unique fiber source that helps nutritionally maintain healthy intestinal bacterial populations, promotes growth of beneficial bacteria. Beet pulp, a moderably fermentable fiber source, also helps maintain intestinal health by providing energy for the cells lining the intestine and promoting small, firm stools.
Different dogs show signs of aging at different times, and much of this variation is associated with size. Larger dogs generally appear 'old' sooner than smaller dogs. The table below lists the age at which various groups of dogs should be transitioned to senior foods, such as IAMS™ ProActive Health™ Senior Plus.
| Weight Range | Age to Begin Transition |
|---|---|
| More than 90 lbs | 5 years |
| 51 to 90 lbs | 6 years |
| 21 to 50 lbs | 7 years |
| Up to 20 lbs | 7 years |
