Chondroitin sulfate is the major glycosaminoglycan (GAGS - see separate article found in this series) found in cartilage. It promotes water retention and elasticity in the cartilage, helping to ensure adequate shock absorption and adequate nourishment of the tissues that line the joint.
Coenzyme Q-10 (CoQ-10, CoQ10 or ubiquinone) exists in abundance in every human and animal body. It is an essential component of the mitochondria, which are the parts of the cell that produce energy from oxygen.
Dimethylglycine is a highly unusual supplement, in that it is extremely popular despite the fact that all of its touted effects have largely been refuted by clinical and laboratory testing. It is most widely used as a performance enhancer by athletes, and in dogs and horses that are bred for racing purposes.
Enzymes catalyze (enhance through increased rate of chemical reaction) virtually every function in the body, from digestion to tissue repair, and from hormone function to energy production. Without them, these same processes would occur much too slowly to be compatible with life.
Most omega fatty acid supplements are made primarily from fish oil or flax seed oil (see the separate handouts on these products in this series), although some products may include other oils such as evening primrose oil, hemp oil, or borage oil.
