Glucosamine and chondroitin are natural substances found in and around the cells of cartilage (the tough, elastic, fibrous connective tissue found in various parts of the body, such as the joints).
Glucosamine is a form of amino sugar that is believed to inhibit inflammation and stimulate cartilage cell growth. At its interior surface, the mucosal layer of the bladder is covered by a film of mucin, which is secreted by the urothelial cells at the surface of this tissue layer and consists largely of the substances known as glycosaminoglycan (GAG).
Glucosamine is a major building block of proteoglycans. It stimulates cartilage cells to synthesize glycosaminoglycans GAG's (mucopolysaccharides). Glucosamine is also known for its anti-inflammatory properties. Chondroitin sulfate is part of a large protein molecule (proteoglycan) that provides cartilage with strength and resilience. Glucosamine, chondroitin sulfate and MSM are sold as nutritional supplements.
Glucosamine supplements are derived from crab, lobster or shrimp shells; and chondroitin supplements are generally made from cow cartilage.
Glucosamine and chondroitin supplements for horses are available in a powders, pellets, liquids and capsules.
