Glucosamine is used to treat a painful condition caused by inflammation, breakdown, and eventual loss of cartilage.

The body uses glucosamine to make other chemicals that build tendons, ligaments, cartilage, and the fluid surrounding joints. The fluid and cartilage cushion joints. Taking glucosamine might increase the cartilage and fluid around joints and help prevent their breakdown.

It acts as a mild anti-inflammatory and is used by the joints to make cartilage components and by the urinary tract for protection. It is one of several natural substances, or nutraceuticals, known as chondroprotective agents (substances that protect articular cartilage during the course of destructive joint disorders).

It’s used in treating arthritis in dogs, horses, and other animals. It’s also often used in dogs to alleviate pain and joint wear caused by hip dysplasia or other structural changes.
