Coenzyme Q-10 is a fat-soluble type of substance called a quinone. It's similar to vitamins E and K. Research has been ongoing since it was first found 40 years ago. It may have benefits for the heart.
Coenzyme Q-10 is made by cells throughout the body. It acts as a catalyst in the respiratory chain. This chain makes energy from carbohydrates. It's abundant in cell membranes, especially in the mitochondria.
Coenzyme Q-10 is a powerful antioxidant by itself. It's also powerful when used with vitamin E.
Levels of coenzyme Q-10 decrease with age. They're also low in people with heart disease. The amount of coenzyme Q-10 in the body peaks around age 20. It then decreases. Intense exercise also makes coenzyme Q-10 turn over faster. This lowers its levels.
Organ meats are good sources of coenzyme Q-10. These include the heart, lung, kidney, spleen, liver, pancreas, and adrenals.
