Coenzyme Q10 CAS 303-98-0

Coenzyme Q10 is an activator of cell respiration and cell metabolism, as well as an important antioxidant and non-specific immune enhancer.


The total amount of coenzyme Q10 in the human body is only 500-1500mg, and its content gradually decreases after the age of 20. Lack of coenzyme Q10 may cause heart failure, gum disease, arrhythmias, stroke, high blood pressure, heart disease, atherosclerosis, cancer, Parkinson’s disease, muscular dystrophy, or AIDS. The adequate intake of Coenzyme Q10 can prevent and treat the diseases caused by the low content of coenzyme Q10.

1. Anti-oxidant and anti-aging;
2. Increase immunity;
3. Helps prevent and treatment of heart disease, liver disease, cancer, and other diseases.
