Coenzyme Q10 belongs is a relatively unknown compound which may play a role in disease prevention. It belongs to a group of compounds called ubiquinones.

Numerous clinical trials have demonstrated the effectiveness of CoQ10 supplement in supporting these vital functions. Peter Mitchell, a UK research chemist, was awarded the Nobel prize in 1978 for discovering how this energy pathway works and the vital role of CoQ10.

Because coenzyme Q10 is involved with energy release in body cells, some research is also being done to determine if it can enhance athletic performance.

Which foods have coenzyme Q10?

Coenzyme Q10 and other ubiquinones are manufactured in the body. These antioxidants can, however, also be found in the following foods: fish oils (e.g. cod liver oil and salmon oil), nuts, fish, meat and vegetables.

Note, however, that cod liver oil is very rich in vitamins A and D, which when taken in excess, can have harmful effects.

Adult levels of coenzyme Q10 supplementation are usually 30-90mg per day. It is recommended that coenzyme Q10 be taken with a meal that contains oil to improve absorption.
