Where are glucosamine and chondroitin found? (3 of 7)

In this third instalment, we discuss where Glucosamine and Chondroitin can be found, both naturally where it is produced within dogs and cats internally and where it is derived from in nature...

Glucosamine and chondroitin are normal substances found in the body of living animals. They are at their highest concentration in cartilage. Unfortunately, through degradation during digestion and processing, almost all of the glucosamine in an animal's diet is unavailable for use. The body, therefore, synthesizes most of its own glucosamine through a biochemical reaction utilizing glucose. In normal healthy animals the body is able to synthesize enough glucosamine to keep the existing cartilage healthy, but when the animal ages or there is damage to joint cartilage it cannot produce enough to keep up with the body's needs. This is where a supplemental form of glucosamine is needed.

Supplemental glucosamine: Glucosamine is a 2-amino derivative of glucose which is obtained through the hydrolysis of chitin, a polysaccharide found in the shell of crustaceans. Crustaceans have a very high concentration of chitin and because the shells are often discarded, provide a reliable and cost effective source of glucosamine.

Chondroitin: Chondroitin is a naturally occurring product found in animal cartilage. Supplemental chondroitin is derived primarily from bovine (cow) cartilage, particularly the cartilage rings of the trachea. It is also derived from shark and whale cartilage. The source does not appear to have any impact on its effect. Though for ecological reasons, many consumers prefer bovine sources.
