Diet plays a central role in your dog’s overall health and well-being, and it stands to reason that you want to provide your dog the best possible source of nutrition in the dog food you choose. But some nutrients, like L-Carnitine, may be unfamiliar or completely foreign. Learn more about this vitamin-like compound and how it can help your dog maintain a healthy weight.
Carnitine, or L-carnitine, is a vitamin-like compound made in the body from amino acids. It's found naturally only in animal-based protein sources. It has been used to help with fat metabolism in other species, and recent scientific studies show that it can help reduce weight in overweight dogs.
This water-soluble substance attaches to fatty acids, transporting them into cellular mitochondria, the part of the cell that converts fat into a usable form of energy. There, they are broken down through oxidation and converted to energy for all tissues, including the heart, liver, and skeletal muscles. Through this process, carnitine helps reduce the storage of body fat and the amount of fat in the bloodstream.
In a study conducted by The IAMS™ Company, overweight dogs were fed similar diets. One group was given a diet supplemented with L-carnitine while another group received a diet without supplemental L-carnitine.
After seven weeks, the group that received the diet without supplemental L-carnitine lost 1.8% body weight compared to 6.4% body weight loss from the group that was fed the L-carnitine supplemented diet. Likewise, body fat was reduced in each group by 2.4% and 4.6%, respectively.1 The study found that L-carnitine promotes loss of body weight and body fat in overweight dogs.
IAMS™ ProActive Health™ Adult Healthy Weight is formulated with L-carnitine that helps turn fat into energy, providing a path to help keep him fit for life.

Obesity is a common problem in dogs, but you can help your pet lose weight. Identifying the causes and following a total weight-management program can result in controlled weight loss and maintenance. A total weight-management program includes evaluating the animal, educating the pet owner, modifying behaviors, and tailoring the program to individual situations.
Obesity is defined as an increase in body weight, beyond the limitation of skeletal and physical requirements, resulting from an accumulation of excess body fat.
Obesity is caused when caloric intake exceeds caloric expenditure. This simply means that a dog eats more energy (calories) than it uses and stores the excess energy as fat.
There are many factors that can contribute to obesity:
Fat
Fiber and Fatty Acids
Carbohydrates and Special Ingredients
In addition, a diet that contains L-carnitine can help dogs metabolize fat. L-carnitine is a vitamin-like compound that helps burn fat.
A total weight-management program can lead to successful weight reduction in the obese dog. Complete evaluation by the veterinarian is always recommended, and owner compliance is essential to success.
IAMS™ and professional veterinary products provide optimum nutrition for animals that can benefit from a weight-management program.
