Glucosamine not only stimulates production of cartilage, but improves joint function and aids in reducing joint pain, including those suffering from arthritis and athletic injuries to the joints.
Chondroitin Sulfate, otherwise known as chondroitinsulfuric acid (CSA) is a type of glycosaminoglycan or member of the polysaccharide chain in proteoglycans.
Proteoglycans consist of units of polysaccharies (95%) and protein (5%). Chondroitin Sulfate acts like a "liquid magnet" to help attract fluid into the proteoglycan molecules. This is important for two reasons: the fluid sweeps nutrients into the cartilage and the fluid acts as a spongy shock absorber.
