Common Name | Coenzyme Q9 |

Description | Coenzyme Q9 (CoQ9) is a normal constituent of human plasma. CoQ9 in human plasma may originate as a product of incomplete CoQ10 biosynthesis or from the diet. The estimated dietary CoQ9 intake is 0 to 1.3 umol/day, primarily from cereals and fats, but this is unreliable because many food items contain levels below the detection limit. Plasma CoQ9 increases after supplementation with CoQ10, and CoQ9 and CoQ10 are significantly correlated. (PMID: 17405953 ). |
