  • Coenzyme Q10 also known as ubiquinone, is a fat-soluble anthraquinone that is widely distributed in nature and is found mainly in the cells of the heart, liver and kidney of yeast, plant leaves, seeds and animals. It binds to mitochondria in cells such as animals, plants, and microorganisms, and acts as a hydrogen donor in the electron transport chain, which is an essential component of the respiratory chain.
  • Coenzyme Q10 has a wide range of applications. A large number of studies have been carried out in Japan, the United States, Switzerland, Italy and other countries. The results showed that coenzyme Q10 has obvious curative effects in cardiovascular diseases, comprehensive treatment of cancer, and prevention of dental diseases. At the same time, effective use in the field of health care products and cosmetics has shown strong demand.
