Undenatured Type II Collagen

UC‑II is short for undenatured type II collagen which is a vital protein forming part of the structure of cartilage. It can be regarded as the 'frame' providing stability to joints while enabling them to work properly.


Studies have proved that the low levels of type II collagen can lead to a lot of joint issues. When cartilage starts to break down, it creates the risk of having pain, swelling, and stiffness.


UC‑II can help the body produce more cartilage cells, stimulate cartilage and joint fluid development, and contribute to fighting joint problems through the immune system. Moreover, the efficiency of UC‑II in pain relief and joint repair is higher than that of glucosamine and chondroitin because it works twice as good.




What the research says.
Undenatured Type II Collagen (UC-II®) Reduces Exercise-Induced Inflammation and Cartilage Degradation in Healthy Labrador Retrievers
Studies have shown that undenatured type II collagen (UC-II®) can greatly decrease post-exercise inflammation and joint deterioration in healthy Labrador Retrievers. The level of inflammatory indicators and markers of cartilage impairment, including IL-6 and cartilage oligomeric matrix protein (COMP), decreased while joint cartilage integrity remained intact. Additional research has shown that UC-II® protects joint cartilage and prevents injury caused by movement while enhancing overall performance.

Six-Month Supplementation with UC-II® Improves Pain, Lameness, and Joint Function in Dogs with Mild-to-Moderate Degenerative Joint Disease
Taking UC-II® regularly for six months can lead to improvements in pain, lameness, mobility, and joint function among dogs with mild to moderate degenerative joint disease. A study involving several clinical sites has revealed that UC-II® proves to be useful not only in terms of its safety profile but also in terms of its effectiveness when used as a long-term dietary supplement for dogs.

UC-II® Alleviates Osteoarthritis in Rats by Suppressing NF-κB-Mediated Inflammation and Cartilage Degradation
Undenatured type II collagen (UC-II®) reduces the inflammation of joints and prevents the breakdown of cartilage in the joints of rats with osteoarthritis by reducing production of inflammation and metabolism products (IL-1β, IL-6, TNF-α, COX-2, MMP-3). The possible mechanisms causing this effect include blocking of the NF-κB pathway, reducing oxidative stress, and changing the processes that govern bone tissue metabolism (RANKL/OPG) providing important evidence for the efficacy of UC-II® in osteoarthritis treatment and joint health preservation.

UC-II® Demonstrates Superior Joint Protection in Companion Animals with Osteoarthritis Compared to Conventional Supplements
The use of undenatured type II collagen (UC-II®) to treat pain, joint mobility, and function, with positive results in dogs and horses with osteoarthritis. UC-II® is able to act in a beneficial way at low doses. The results of several studies show that UC-II® is more effective than other medications such as glucosamine and chondroitin sulfate. The review indicates that UC-II® is a promising remedy that has been getting increasing recognition from scientific studies and can be used for nutritional treatment of osteoarthritis in pets.
