UC-II Collagen for pets: Scientifically proven joint support

Healthy joints are essential for the quality of life of pets. This presents an opportunity for manufacturers, veterinarians, and distributors to offer products that truly make a difference. UC-II collagen for pets is one such ingredient: scientifically proven, effective, and perfectly usable in modern formulations.

What is UC-II collageen?

UC-II® is an undenatured type II collagen that activates the animal’s natural immune response to support joints. Unlike hydrolyzed or denatured collagen, UC-II® retains its 3D structure. This allows the immune system to recognize and utilize it through a process called oral tolerance.

Unique mechanism of action via oral tolerance

UC-II® works differently than traditional building block supplements like glucosamine and chondroitin. The intact collagen activates the immune system in the intestines through oral tolerance, stimulating anti-inflammatory T cells. These help reduce inflammation and support cartilage repair. In this way, the body actively contributes to protecting its joints.

Superior results compared to glucosamine & chondroitin

UC-II® has been shown in several animal studies to be more effective than the classic combination of glucosamine and chondroitin. In dogs and horses with osteoarthritis, up to 88% less pain was observed, with a significant increase in mobility. Even in healthy, active dogs, UC-II® led to improved performance and lower inflammation levels. This makes it a premium ingredient for both preventive and therapeutic applications.

Proven effective in dogs, cats and horses

UC-II® has been extensively studied in dogs, cats and horses:

  • Dogs: less pain, more mobility.

  • Cats: high palatability and excellent absorption.

  • Horses: Significant improvement in joint comfort compared to traditional means.

With over two decades of research, UC-II® is one of the best-documented joint health ingredients in the pet industry.

Low daily dose of 40 mg of UC-II collagen for pets

Just 40 mg per day is enough to support the joints of dogs and cats. This means smaller tablets or treats, lower costs, and higher compliance – ideal for brands that want to combine ease of use and effectiveness.

Formulatable in treats and food

UC-II® is exceptionally flexible in its use in various formulations. Thanks to its heat- and digestion-resistant structure, it maintains its effectiveness in, among other things:

  • Soft chews: Very suitable because of good stability and high compliance in animals.

  • Powders: Easy to add to wet food or dose directly.

  • Liquids: Possible with modified formulation; requires attention to pH and preservatives.

  • Gummies: Popular in the human sector, emerging in the pet segment.

  • Tablets & chunks: Proven stable and effective for long-term use in feed.

The graph below illustrates the applicability of UC-II® per formulation based on three criteria: stability, compliance, and ease of formulation.

UC-II® is stable and processable in various applications, such as chews, tablets, and complete pet food. Its heat-resistant structure makes it suitable for processing without loss of effectiveness.
