Chondroitin is a high molecular weight polysaccharide, i.e. a long chain made up of sugar molecules. Chondroitin sulfate is one of the essential components that make up the cartilage of the joints, giving it a high resistance to compression. Its physiological function is to maintain the elasticity of the cartilage itself, prevent its degradation and attenuate inflammation by reducing the production and activation of inflammatory mediators in the cells that produce the components of the cartilage. For these reasons, the use of Chondroitin sulphate could: contribute to the structural and functional maintenance of the joint, confer a certain chondroprotective activity, reduce pain in the course of degenerative diseases, such as osteoarthritis, reduce joint inflammation and improve mobility. joint during diseases such as osteoarthritis.
