What is coenzyme Q10?
Coenzyme Q10 (CoQ10) is a vitamin-like compound that is produced by the body itself. It is essential for energy production in the cells, especially in the mitochondria, the power plants of the cells. CoQ10 occurs in two forms: oxidized (ubiquinone) and reduced (ubiquinol), and the body can switch between these two forms depending on the needs of the cells. In addition to its energetic function, CoQ10 is a powerful antioxidant that may help neutralize harmful free radicals. Although the body produces CoQ10 itself, it can also be obtained from supplements and certain foods. The balance between the two forms can be an indication of how well the body is coping with oxidative stress, while an imbalance may indicate reduced antioxidant activity.
How does CoQ10 work
CoQ10 acts primarily as an antioxidant and energy supplier in the body. It increases the production of important antioxidants such as superoxide dismutase (SOD) and reduces harmful lipid peroxides. In the mitochondria, CoQ10 plays a crucial role in the electron transport chain, which is essential for the production of ATP, the cells' most important energy currency. It also helps regenerate vitamin E in its active form, contributing to overall antioxidant protection. In certain conditions such as type 2 diabetes, CoQ10 can improve blood glucose control and lipid profile by reducing oxidative stress and promoting fatty acid oxidation. However, some mechanisms, such as its role in activating certain cellular protective responses, need further research to be fully understood.
