Feeling more tired than usual? It might not just be your schedule. As we get older, the body’s natural ability to produce energy slows down – partly due to a drop in a nutrient called CoQ10. Short for Coenzyme Q10, this substance is found in nearly every cell in your body. It plays a central role in how your body turns food into usable energy.

What Is CoQ10?

CoQ10 is a nutrient that helps generate energy in your cells. It’s found in the mitochondria – the part of the cell that acts like a power plant, producing energy. Think of it as a key ingredient your body needs to keep everything running smoothly, from your heart to your brain and beyond. The body makes its own CoQ10, but levels naturally decrease with age (1). They can also be depleted by common medications like statins, which are used to lower cholesterol.
