A nutritional supplement to support joint and connective tissue health. The three forms of glucosamine, N-Acetyl Glucosamine, Glucosamine Hydrochloride, and Glucosamine Sulfate are naturally occurring substrates used by the body for the biosynthesis of special macromolecules called glycoproteins, glycosaminoglycans (GAGs), and proteoglycans. Glucosamines are part of the structural elements in cell walls, intercellular spaces, and connective tissues. Glucosamines give shape, elasticity and rigidity to such tissues as cartilage, tendons, ligaments, intervertebral discs, and mucous membranes. Glucosamine Sulfate and Glucosamine Hydrochloride help glycosaminoglycans to hold more water thereby increasing joint flexibility, cushioning ability and resiliency. N-Acetyl glucosamine is produced from Glucosamine in the body and supports proper functioning of the digestive tract lining. All three forms of Glucosamine are considered important nutritional factors..
