Dietary supplement based on a highly concentrated glucosamine and chondroitin formula. It provides potent amounts of other nutrients considered useful for joint care. Glucosamine is an element that the body needs to synthesize glycosaminoglycans (GAGs), structural polysaccharides that form a large part of the intercellular matrix of connective, epithelial and bone tissues, as well as in the intercellular medium. Chondroitin sulfate is an important component of most vertebrate and invertebrate tissues, and is present mainly in all those with a large extracellular matrix, such as those forming the body's connective tissues, cartilage, skin, blood vessels, as well as ligaments and tendons.
