Coenzyme Q10, or CoQ10, is a natural substance found in every cell of the body. CoQ10 plays an important part in energy production, serving as a crucial component in the generation of ATP, the body’s main source of fuel. Over time, the amount of Co Q10 produced by the body begins to naturally decline. It’s believed that insufficient levels of coenzyme 10 may lead to less efficient functioning of organs, especially for those with higher concentrations of the co q10 enzyme, including the heart and liver. Supplementing with co q 10 vitamins may help replenish the body’s stores of CoQ10, giving cells the raw materials they need to function properly.
