CoQ10 stands for Coenzyme Q10 and it really is a natural antioxidant that is synthesized by our bodies. CoQ10 is present in many foods. There are also a number of CoQ10 supplements available in the market.
Coenzyme Q10 is a part of the ubiquinone family of compounds. It is soluble in fats (otherwise known as lipids) and it is located in almost all cell membranes. This antioxidant can exist in three different oxidation states – completely reduced ubiquinol (here is the active antioxidant type), radical semiquinone intermediate, and totally oxidized ubiquinone. Because these antioxidants can be synthesized by us, CoQ10 really can't be considered a vitamin. CoQ10 supplements that are multi-ingredient can include multiple types of CoQ10.
