A cell’s mitochondria are its energy factory. So anything you can do or take to improve those powerhouses can give you more energy. Coenzyme Q10 is just such a nutrient. It increases the ability of the mitochondria to create adenosine triphosphate—ATP—which is like cell jet fuel. Interesting that creatine also plays a role in boosting ATP, so CoQ10 and creatine may be a good preworkout elixir for helping you power up more weight for greater growth stimulation. Start with about 50 miilligrams of CoQ10.
