Coenzyme Q10 (CoQ10) is a nutrient found naturally in the human body, but as we age, its production decreases. The lack of CoQ10 is often associated with the harmful effects of oxidative stress. Coq10 coenzyme exists in every cell in the human body. However, its higher concentrations are found in the organs with the highest energy requirements, such as the heart, kidneys, lungs and liver. One of its most important functions is that it contributes to the production of energy at the cellular level. Coenzyme CoQ10 is actively involved in the creation of ADENOSINE ATP triphosphate, which is responsible for transferring energy to cells. But it is not only necessary for the production of cellular energy, but also for the protection of cells from the damage caused by free radicals. CoQ10 acts as an antioxidant, which protects cells from damage and plays an important role in metabolism. As a powerful antioxidant, it can increase the absorption of other essential nutrients. It has been shown to help recycle vitamin C and vitamin E, further maximizing the effect of vitamins and antioxidants already found in the body.
