The Role of Tocopherols in Your Dogs Diet - Pet Super Market

Your beloved canine companion's sparkling eyes, boundless energy, and wagging tail are signs of a happy, healthy dog. But did you know that beneath these visible signs of vitality, unseen factors like the food they eat play an essential role in their well-being?

One ingredient you've likely seen but perhaps not understood is "tocopherols" - a component in your dog's diet that holds more significance than you might realize. Tocopherols, a form of Vitamin E, serve dual roles as crucial antioxidants supporting your dog's health and as natural preservatives in their food.

It might surprise you that the World Health Organization recommends a daily intake of 4-5mg of Vitamin E per kg of body weight for dogs. Curious? Let's delve into why tocopherols matter in your dog's diet.

Why Tocopherols are Included in Dog Food

Tocopherols play a crucial role in dog food that extends beyond just nutrition. To appreciate their importance, it's essential to understand that tocopherols are a form of Vitamin E, a powerful antioxidant.


Antioxidants, as the name suggests, combat oxidation, a chemical reaction that can produce free radicals, leading to cell damage. By neutralizing these free radicals, antioxidants help protect the body's cells from damage. This is particularly crucial for dogs, whose bodies, like ours, are composed of billions of cells working together to keep them healthy.

Natural Preservative

In addition to their role as antioxidants, tocopherols are often added to dog food as a natural preservative. Commercial dog foods must have a long shelf-life to remain fresh from when they are packaged until they reach your dog's bowl. Tocopherols help in this process by preventing the oxidation of fats and oils in the food, which can lead to rancidity.

Alternative To Synthetic Preservatives

Using tocopherols as preservatives are generally regarded as a healthier alternative to synthetic preservatives like BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene), which have been the subject of health concerns and controversy.

Therefore, when you spot tocopherols on your dog food label, it's a sign that the manufacturer is committed to providing your dog with vital antioxidants and ensuring that the food stays fresh naturally. In the next section, we'll look more closely at the health benefits of tocopherols, or Vitamin E, for your dog.

Health Benefits of Tocopherols (Vitamin E) for Dogs

Tocopherols, or Vitamin E, are much more than just food preservatives; they have many health benefits that play a significant role in keeping your dog in the best shape possible. Below, we discuss a few of these benefits:

Immune System Support

Vitamin E plays an essential role in bolstering your dog's immune system. It stimulates the body's defense cell production, effectively helping your dog fight sickness and infection. This is especially important for young pups, older dogs, or canines with a weakened immune system.

Skin and Coat Health

Ever wondered why your dog's coat is shiny and healthy? Vitamin E contributes to this too! It helps maintain skin and coat health, keeping your dog's fur smooth and shiny while preventing common skin issues like flaky and itchy skin.

Eye Health

Research suggests that Vitamin E, in conjunction with other antioxidants, can help slow the progression of age-related eye diseases in dogs, such as macular degeneration or cataracts. This is particularly beneficial for senior dogs.

Muscle Function and Recovery

Vitamin E is crucial in enhancing your dog's muscle function and recovery. It helps promote muscle strength, particularly for working dogs or those with high physical activity.

Prevention of Vitamin A and Fats Oxidation

Vitamin E prevents the oxidation of Vitamin A and fats in your dog's body, which are crucial for their health. Vitamin A is essential for vision, growth, and immune function, while fats provide the diet's most concentrated energy source.

Natural vs Synthetic Tocopherols in Dog Food

When examining your dog's food labels, you might notice terms like "mixed tocopherols" or specific forms of Vitamin E like "d-alpha-tocopherol."

These are clues about the type and source of tocopherols used in the product. Let's delve into the differences between natural and synthetic tocopherols:

Natural Tocopherols

Natural tocopherols are derived from vegetable oils, primarily soybean and sunflower oil. They usually appear on labels as d-alpha-tocopherol, d-beta-tocopherol, d-gamma-tocopherol, or d-delta-tocopherol. The "d" prefix indicates that these tocopherols are derived from natural sources.

Natural tocopherols are typically more bioavailable than their synthetic counterparts. This means they are more easily absorbed and used by your dog's body, making them a more efficient source of Vitamin E.

Synthetic Tocopherols

Synthetic tocopherols are made in a lab and are typically listed as dl-alpha-tocopherol or dl-alpha-tocopherol acetate on dog food labels. The "dl" prefix is an indication of their synthetic origin.

While synthetic tocopherols are more cost-effective and commonly found in cheaper dog food brands, they are not as easily absorbed by the body as natural tocopherols.

Which is Better for Your Dog?

The former is generally considered the better option when choosing between natural and synthetic tocopherols due to their higher bioavailability. However, both forms will provide your dog with the necessary Vitamin E and can serve as effective preservatives in dog food.

It's worth noting that a dog food's quality isn't solely determined by whether it uses natural or synthetic tocopherols. Many other factors, such as the quality of the protein source, the balance of other nutrients, and the absence of harmful additives, are equally important considerations when choosing the best food for your dog.

How to Choose a Dog Food with the Right Tocopherols

Ensuring your dog receives the appropriate amount of tocopherols (Vitamin E) in its diet is critical to promoting overall health and well-being. Here's what to keep in mind when selecting a dog food with the right tocopherols:

Reading the Labels

Look for 'tocopherols' listed in the ingredients. If you find the 'dl-' prefix, know they are synthetic versions, whereas 'd-' indicates a natural source. Both types offer benefits, but natural tocopherols are typically more bioavailable.

The Right Balance

The overall balance of nutrients is crucial. Dog food should provide a complete and balanced diet. Even though tocopherols are essential, they are only one piece of the nutritional puzzle.

Check the Expiry Date

As tocopherols act as natural preservatives, checking the expiry date on dog food is critical. As the food nears its expiration date, the effectiveness of tocopherols decreases, and the food may become rancid.

Seek Professional Advice

Every dog is unique, and dietary needs vary based on age, breed, health status, and lifestyle. Consult with a vet or a pet nutritionist to understand the specific dietary needs of your dog. They can help guide you to the best diet for your pet, considering tocopherols and all other necessary nutrients.

Consider Dietary Supplements

If your vet determines your dog could benefit from additional Vitamin E beyond what's in their food, they may suggest a dietary supplement. Always consult a vet before adding any supplements to your dog's diet to ensure it's necessary and safe.


Tocopherols play a crucial role in your dog's diet. They serve as a natural preservative, ensuring your dog's food remains fresh, and they provide valuable health benefits as a form of Vitamin E.

From supporting the immune system and promoting skin health to aiding muscle recovery and preventing cell damage, tocopherols are nutritional heroes in your dog's food. Remember, every ingredient in your dog's diet has a purpose and contributes to their well-being.

So the next time you pick up a bag of dog food, take a moment to read the label and appreciate the vital role each ingredient, including tocopherols, plays in keeping your beloved canine companion healthy and happy.
