Cosequin® ASU, the joint health supplement veterinarians and champions choose when performance matters, now comes in a tasty, tiny pellet preferred by horses and horse owners. Our scientifically researched combination of trademarked FCHG49® Glucosamine and TRH122® Chondroitin Sulfate plus NMX1000® Avocado/Soybean Unsaponifiables (ASU) has been shown in cell culture studies to be more effective in inhibiting certain degradative enzymes than glucosamine and chondroitin sulfate alone.
