Avocado/Soybean Unsaponifiables (ASU), Glucosamine, and Chondroitin Sulfate Shown Effective in Equine Cells at Protecting Cartilage


Edgewood, MD: Nutramax Laboratories, Inc. is pleased to announce results of cell culture research presented in October at the 2007 American College of Veterinary Surgeons Veterinary Symposium in Chicago. The results showed that the combination of avocado/soybean unsaponifiables (ASU), glucosamine hydrochloride, and chondroitin sulfate is effective in equine cartilage cells (chondrocytes) and bone cells (osteoblasts) at inhibiting expression and decreasing production of mediators involved in joint cartilage breakdown. This study expands on research demonstrating the compounds' effects in supporting and protecting joint health in other species (canine, feline, and human cells). The protective effects of the compounds may minimize cartilage breakdown by suppressing the release of the mediators responsible.

The study showed that the combination of NMX1000® avocado/soybean unsaponifiables, FCHG49® glucosamine hydrochloride, and TRH122® low molecular weight chondroitin sulfate decreased expression of the enzyme cyclooxygenase-2 that regulates the production of the mediator prostaglandin E2 (PGE2) in both equine chondrocytes and equine osteoblasts. Production of PGE2 was also reduced by up to 80% in chondrocytes and by 67% in osteoblasts versus control. Effects on osteoblasts are relevant to cartilage health as changes brought about by mediators on the bone underlying cartilage, known as subchondral bone, can lead to breakdown of cartilage.

"These results are very exciting," said Tara Cullen, equine product manager. "They provide further evidence to both veterinarians and horse owners that the use of ASU, glucosamine, and chondroitin sulfate is an excellent option in the management of joint health in horses."NMX1000® avocado/soybean unsaponifiables, FCHG49® glucosamine hydrochloride, and TRH122® low molecular weight chondroitin sulfate are found combined with methylsulfonylmethane (MSM) in the advanced joint health supplement for horses, Cosequin® ASU.
