Not only is the joint supplement ingredient type II collagen effective for arthritic horses, it also might be more effective than glucosamine and chondroitin sulfate, reported Ramesh C. Gupta, DMV, MVSC, PhD, DABT, FTAS, professor and head of the Toxicology Department from Murray State University in Kentucky.

Type II collagen is the predominant form of collagen in the cartilage that lines the ends of the bones inside of moveable joints. The type II collagen Gupta used in the study was isolated from chicken sternum (breastbone) according to good manufacturing practices (GMPs)—a set of guidelines that ensure products like nutritional supplements are produced safely.

Horses were selected based on signs of lameness, joint effusion, reduced joint flexibility, crepitation (a crinkly feeling) of the joint on manipulation, and increased lameness upon flexion. Horses with these signs were then randomized into one of five groups receiving: a placebo; 320, 480, or 640 mg undenatured type II collagen; or 5.4 g of glucosamine with 1.8 g chondroitin. Five to six horses were included in each group, and supplements were administered for 150 days.

Horses supplemented with all three doses of type II collagen had significant improvements in their condition. Horse supplemented with glucosamine and chondroitin sulfate also showed a significant decrease in pain. However, the improvement in condition was not as profound as horses in the type II collagen groups
