9 Foods known to be the best source of coenzyme Q10


Coenzyme Q10 was discovered in 1957 by Dr. Frederick Crane. The compound is made from our body and remains stored in the mitochondria, the powerhouse of cells. Production of coenzyme Q10 decreases with aging. Therefore, elderly people are likely to suffer from its deficiency which is manifested through Vitamin B6 deficiency. This substance occurs in the plants and animal tissue. In animals, including human beings, it is found in kidney, liver, heart and pancreas.

Food types which have coenzyme Q10


Foods rich in CoQ10 are beef, chicken, pork, fish, vegetables, oils, nuts, fruits and dairy products. Liver, kidney and heart are the areas where maximum amount of this substance is found.
