Did you know?

  • Scientific findings show that the dog’s own immune system can play a significant role in aggravating normal joint function. Loose bits of collagen released from cartilage in the joint fluid can be recognized as foreign bodies which activate the immune system. Despite the immune system’s best intentions, this reaction may cause more harm than good. As the immune system responds by attempting to destroy the collagen, it can create swelling, stiffness and soreness.
  • Continued wear and tear on cartilage can take a toll on normal joint health.
  • UC-II® is undenatured collagen type II, which comes from chicken sternum. 
  • Type II collagen is the most abundant protein in cartilage. 


Nonhydrolytic UC-II (yielding 10 mg of active undenatured collagen type II), 40 mg; omega-3 fatty acids (flaxseed oil), 80 mg; omega-3 fatty acids (fish oil), 20 mg; and vitamin E, 42 mg (21 IU).
