Co-enzyme Q10 (CoQ10 or ubiquinol) is an essential nutrient present in almost every cell of the human body.

The following foods also contain CoQ10:

• oily fish

• organ meats

• eggs

• nuts

• whole grains

CoQ10 is stored in an area of human cells called mitochondria. It acts as an antioxidant, neutralizing harmful free radicals and has associations with energy, protecting cells, and providing heart benefits. It also plays a vital role in energy production and DNA replication and repair.

Naturally occurring levels of CoQ10 decrease with age. Your mitochondria, the powerplants of your cells naturally start to slow down and produce less CoQ10, and therefore energy, by as much as 10% less every decade.

Scientists have identified associations between CoQ10 deficiency and heart disease and cancer. There are links between oxidative stress and a range of disorders, including Alzheimer’s disease and Parkinson’s disease. 

Improving heart health
CoQ10 might help treat specific heart conditions, such as congestive heart failure and high blood pressure, particularly among older individuals. CoQ10 might help people recover from some types of heart surgery.

Reducing migraines
CoQ10 may be effective in preventing migraines, although the research to support this is still limited. It is possible that CoQ10 has this effect because it keeps the mitochondria in the cells healthy.

Easing statin side effects.

Some research suggests that CoQ10 might help ease muscle weakness that is due to taking cholesterol-lowering medications, known as statins.
