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.

Active dogs thrive on diets high in fat. To preserve a high-fat dry kibble diet, however, is a challenge. The IAMS research team met that challenge with an effective preservative system used in all our dry dog food products, such as IAMS™ ProActive Health™ Adult MiniChunks.
The preservative system features a special blend of mixed tocopherols. Tocopherols are antioxidants extracted from vegetable oils. There are four major types of tocopherols. Vitamin E, also known as alpha-tocopherol, is commonly used in dog foods, though a specific mixture of the different tocopherols protects against rancidity.
Our preservative system slows the rate of oxidation and allows for an extended shelf life.
Wet foods, such as IAMS™ ProActive Health™ with Chicken and Whole Grain Rice Pate, do not require preservatives because they are preserved by packaging. When the ingredients are mixed and ready for cooking, the mixture is packed into cans, trays or pouches and cooked in a retort. Similar in principle to a pressure cooker, the retort sterilizes and preserves the product.
The cans, trays or pouches are then cooled under conditions that assure product sterility and container integrity.
Thorough shelf-life testing is conducted on all our products. In general, shelf lives for various types of products are:
24 months for wet foods
16 months for dry foods
12 months for biscuits
By using a preservative system in our dry dog food and preservation through packaging in our wet dog food, IAMS makes sure the food your dog eats is well-balanced and nutritionally beneficial.
