CoQ10 or ubiquinone is essentially a vitamin or vitamin-like substance. CoQ10 is a micronutrient essential to all human life. It is a naturally occurring nutrient that works as a co-factor in the body’s electron transport system where all of the body’s energy is derived. CoQ10 regulates the flow of oxygen moving in and out of the mitochondria, which are the cell’s power plants. The body’s cellular power plants can’t function without CoQ10 (CoEnzyme Q10). Taking Coenzyme q10 as a dietary supplement may aid in maintaining youthful levels of this vital substance.
