what Is Welactin?

Welactin is a specially prepared salmon oil manufactured to maintain a high content of Omega 3 fatty acids. Welactin is manufactured in two separate formulations, Welactin for Cats, and Welactin for Dogs. Each has been carefully formulated for maximum palatability.

What Are Omega 3 Fatty Acids?

Specific fatty acids known as “Omega 3 fatty acids” are the “good health” fatty acids that you may have read about for human heart health. Humans have been encouraged to eat larger amounts of certain fish, which are high in Omega 3 fatty acids. The two predominant Omega 3 fatty acids are docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).

How Can Welactin Help My Pet?

These two fatty acids have been shown in veterinary research to perform many functions. In dogs and pocket pets, Omega 3 fatty acids support a normal heart rhythm.1-6 Omega 3 fatty acids support many other organ systems in the body, too, providing important benefits as pets age. Omega 3 fatty acids have been shown to protect kidney function,7-15 which is especially important to older animals who are more prone to problems in kidney function. They also support the body's immune system,16-18 again beneficial because as animals age, immune function may decrease. Omega 3 fatty acids can support skin and coat health as well.19,20 Because the outer layer of skin cells “turns over” (sloughs off and is replaced by other cells), the skin can benefit from long-term administration of Omega 3 fatty acids.21

Welactin contains a higher proportion of the Omega 3 fatty acid DHA than do other fish oil products. This is ideal as DHA has a function in many organ systems. DHA is a major component of cell membranes. It affects fluidity and stability of cell membranes,22,23 which means it has a key effect on every-day function of all of the cells in the body. More specifically, it is essential to early development of the brain and retina22-24 and has been shown to be very important later in life as well in protecting brain cells;25,26 a continual supply is needed as DHA is gradually broken down and eliminated.27 This importance to the nervous system has been demonstrated in studies which showed that DHA supplementation has beneficial effects on brain function and learning28-31 and on vision.31 Another study showed that dogs with compromised retinal function had lower levels of DHA in the bloodstream; therefore, supplementing with DHA may be helpful.24

Administering DHA specifically rather than oils that contain precursor fatty acids to DHA may be important as some studies have shown that cats and dogs may not be able to readily use other fatty acids to make DHA in the body.24,32,33

As this demonstrates, Welactin has far-reaching effects throughout the body and can help “turn back the clock” in your dog and “activate your cat ”!

How Do I Know That Welactin Is Absorbed By My Pet?

Welactin has been clinically evaluated in a carefully designed research study and was shown to increase levels of DHA in the blood three times over baseline levels in cats and more than five times over baseline levels in dogs.

What Changes Should I Expect To See In My Pet With Welactin?

While many of Welactin's important functions are at work inside your pet's body, changes that you may notice are an improvement in your pet's activity level, attitude, alertness, and general appearance.

How Do I Give Welactin?

Welactin is a tasty liquid and is easily administered with the accompanying pump over your pet's food. Please follow the administration instructions, which are based on your pet's weight, found on the label. In most cases, Welactin is administered longterm for continuing benefits.

Are Any Side Effects Seen In Animals Given Welactin?

No side effects were observed and no harmful effects on bloodwork were noted when Welactin was administered to cats and dogs in a trial. Rarely, side effects, including vomiting and diarrhea, itching, and lethargy, have been reported with other fish oil supplementation.34 While there are no known interactions or side effects with administration of Welactin, if your pet has a medical condition, you should always consult with your veterinarian before administering any nutritional supplement or drug.

Doesn't My Pet Get Enough Omega 3 Fatty Acids From Food?

Another type of fatty acids are Omega 6 fatty acids. While the “natural diet” of animals in the past contained more balanced levels of Omega 6 and Omega 3 fatty acids,35 pet foods today may have higher amounts of the Omega 6 fatty acids relative to the amounts of Omega 3 fatty acids.36 Supplementing with the Omega 3 fatty acids in Welactin can, therefore, help re-establish the balance between these two kinds of fatty acids.

While some pet foods contain added levels of flaxseed oil, which contains alpha-linolenic acid, a precursor to DHA and EPA, the body may not be able to use it to make the DHA that the cells need.32 A few pet foods are fortified with the specific fatty acids DHA and EPA; however, levels are often well below the amounts found in Welactin. In addition, even if the amounts added are initially adequate, DHA and EPA are prone to break down so that they may not be maintained in the food. Welactin is specifically formulated to provide optimal amounts of DHA and EPA: levels that are both beneficial and safe for your pet.

Why Did My Veterinarian Recommend Welactin Instead Of Fish Oil Capsules Or Other Liquids?

The salmon oil found in Welactin differs from the fish oil found in capsules or other liquids in several ways - from palatability (how much your pet will like the taste) to levels of DHA and EPA.

In regards to palatability, Welactin has been evaluated in “taste tests” with dogs and cats.37 When Welactin was added over the food, all of the dogs ate it. In addition, when dogs were then offered their food with and without Welactin, more of the dogs preferred their food with Welactin. In the cat taste test, Welactin was also shown to be palatable.

The levels of DHA and EPA are an issue in two ways. First, most other fish oils have a higher proportion of EPA, but Welactin has a higher proportion of DHA, with all of its important benefits, compared to these other supplements. Second, there is less oversight for supplements (compared to drugs), and a recent report showed that over 25% of fish oil products tested contained less DHA than what was listed on the label.38 Another problem with fish oil products is that they can potentially turn rancid (they will then have a foul odor). In addition to containing vitamin E, which helps protect against this, Welactin contains other ingredients to help maintain freshness and stability. Finally, as heavy metal contamination is a potential problem with any fish-derived products, Welactin is monitored for the presence of heavy metals.

Where Can I Purchase Welactin?

Welactin is available only through your veterinarian. Your veterinarian can help you decide if Welactin is right for your pet and help you monitor your pet's response to it.
