CoEnzyme coQ-10 does sound like it has been grown in a petri-dish by scientists, but it’s actually 100% natural - our bodies make it. You can find it in the mitochondria of each and every cell in the body and it does a very important job. This vitamin-like substance ensures chemical reactions in your body run smoothly. The kidneys, lungs, liver, heart and skeletal muscles require a lot of energy to run and consequently contain the highest concentration of CoEnzyme coQ-10. One of CoEnzyme coQ-10s most prominent roles is helping with the production of adenosine triphosphate (ATP). ATP is a molecule that helps to deliver energy to every cell in the body, from the cells in your heart to the cells in your digestive system – so it’s pretty important!
