As we age, the levels of antioxidants in our bodies fall. Due to the natural course of aging and the increasing reach of environmental toxins, it may be difficult to get the optimal amount of antioxidants through food alone; dietary supplements may be of benefit to optimize and maintain a healthy cellular redox balance. CoQ10/Ubiquinone is one of the best for your heart health and energy. CoQ10 is a coenzyme, meaning that it partners with other enzymes in the body to produce particular reactions. It plays two vital roles in cellular and body health: energy production and free radical production. After age 40 the liver conversion rate of CoQ10 to Ubiquinol slows down. It is better to get Ubiquinol already in its active form which is utilized better in the body. You will be able to feel the difference.
