It plays a significant role in the body to produce energy in the mitochondria, helping to metabolize fats and carbohydrates, as well as maintaining the cell membrane elasticity. It also participates in the production of other key enzymes used for the production of Adenosine 5'-triphosphate (ATP), which is burned by the body for energy production but also for transporting energy between mitochondria and cells.

Yearly research has shown that beyond its contribution to energy production, CoQ10 supports the healthy functioning of the cardiovascular and immune system. In addition, CoQ10 is an effective lipid-soluble antioxidant that provides protection to the structure of vessels and other tissues from attack by free radicals but can also positively affect the aging process. Studies have demonstrated the importance of CoQ10 in maintaining a healthy intracellular activity while comparing its effectiveness with that of vitamin E, one of the most effective antioxidants.
