UC-II® Collagen Triple action Capsules
Advanced joint collagen, clinically proven
The perfect partner to our entire canine range, UC-II® collagen provides a powerful additional layer of joint support. This clinically studied ingredient helps maintain healthy cartilage, supports strong and flexible joints, and aids everyday recovery at just 40mg per day.
Unlike standard bovine and marine collagen supplements, UC-II® is a unique form of undenatured Type II collagen that works through a completely different and far more targeted biological pathway. We combine it with manganese and Vitamin C to enhance and maximise joint support.
How does UC-II® work?
UC-II® collagen works via a process called oral tolerance, a natural immune system response that supports joint health from within.
As we age, the immune system can become over reactive and begin to mistakenly target the body’s own cartilage. This low grade immune activity contributes to stiffness, discomfort and cartilage breakdown over time.
When undenatured Type II collagen is taken orally, it interacts with immune cells in the gut. This helps “re-educate” the immune system so it becomes less reactive towards joint cartilage. Clinical studies show that UC-II® collagen can significantly:
- Reduce joint discomfort
- Improve joint function
- Provide long-term cartilage protection
This effect is seen at just 40mg per day, making it one of the most efficient collagen supplements for joint care. Our Hydrolysed Type 2 collagen powder provides the raw building blocks for cartilage whilst UC-II® helps protect what you already have, making them the perfect partners.
Why Type II Collagen Matters?
There are three main types of collagen in the body:
- Type I – supports skin, hair and connective tissue
- Type II – supports joints and cartilage
- Type III – supports skin and muscle structure
Articular cartilage is made up of approximately 85–90% Type II collagen.
This makes Type II collagen the most important and most effective form for targeted joint support.
Unlike marine or bovine collagen (Types I and III), which are used in much larger doses for skin and beauty, Undenatured UC-II® collagen is required in very small amounts to influence joint health because it works through immune regulation rather than gut absorption.
What makes UC-II different?
UC-II® is a patented, clinically studied form of undenatured Type II collagen, naturally sourced from chicken cartilage and processed at very low temperatures to preserve its structure.
“Undenatured” means the collagen maintains its three-dimensional structure, which is essential for triggering oral tolerance. This makes UC-II® a valuable part of joint support alongside our Hydrolysed Type 2 collagen powder.
Why joints change with age?
As dogs get older, the body produces less collagen and the collagen it does produce is lower in quality. Cartilage becomes weaker, and recovery slows, which can lead to:
- Stiff, achy joints
- Reduced mobility
- Slower recovery after activity
UC-II® works to help protect cartilage, support joint comfort, and maintain mobility as part of a comprehensive joint care regime.

- UC-II Collagen
UC-II collagen is a unique form of undenatured Type 2 Collagen that works with the immune system to help maintain joint comfort, mobility, and flexibility.
- Manganese
Manganese supports joint health by contributing to the formation of healthy cartilage, collagen, and connective tissue while protecting against oxidative stress. It is important for growth, joint health and many other functions in a dog's body. Dogs can't produce manganese so it must be obtained through their diet or an external source.
- Vitamin C
An extracellular antioxidant, important for connective tissue integrity and neutralising harmful free radicals. An essential vitamin for collagen synthesis.
