Coq10 has long been and continues to be one of my favorite vitamins. Coq10 is found in the body in the powerhouse of all our cells called the mitochondria. The mitochondria makes our energy – energy for the brain, the heart, the kidneys and everything else. This makes coq10 a big deal. The heart and the brain need and use a lot of energy. The muscles can do. So I use it for many different conditions and situations.
