Glucosamine is a naturally occurring substance in joints and cartilage that decreases with age and is therefore used to prevent joint degeneration and maintain joint health. Glucosamine increases cartilage health, protects articular cartilage from degeneration and inhibits the activity of enzymes that destroy cartilage. Glucosamine maintains optimal joint function and well-being. The use of glucosamine increases the glucosamine content of synovial fluid. About 90% of glucosamine taken orally is absorbed.
