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.
Also called linseed oil, flax seed oil is derived from the seeds of the flax plant and has been proposed as a more aesthetically pleasing alternative to fish oil supplements (which may impart a fishy smell to the breath or skin). Flax Seed oil contains higher levels of alpha-linolenic acid (ALA) than fish oil, and also contains omega-6 fatty acids.
