Coenzyme Q10 , or CoQ10, is a key molecule for your cellular well-being. Naturally present in the body, it helps produce energy and protect cells from aging.

But what exactly is coenzyme Q10 used for? Who can benefit from its use? This guide tells you everything you need to know.

What is coenzyme Q10 and why is it so important for your body?

CoQ10 is a vitamin-like substance that is present in all cells of the body, especially the heart, kidneys, liver , and muscles.

Its main function is to intervene in the production of cellular energy (ATP) in the mitochondria. It also acts as an antioxidant , helping to protect cells from oxidative damage, one of the main accelerators of aging and many chronic diseases.

With age, stress, and certain medications (such as statins), CoQ10 levels decrease, and with them, our vitality.
