Coenzyme Q10 (CoQ10) is a fat-soluble, vitamin-like antioxidant. It is used by cells called mitochondria to generate energy and to protect cells from oxidative damage.
Q10 is present in all cells of the body. Interestingly, the highest concentrations of Q10 are found in high-energy organs like the heart.
For normal heart function a steady supply of coenzyme Q10 is required.
Previous research has reported that 75% of heart disease patients had low levels of coenzyme Q10 in their blood and decreasing levels in their heart tissue as the heart disease progressed.
Coenzyme Q10 is a crucial nutrient with multiple important functions fpor heart health:
-
Energy production: helping heart-muscle cells produce ATP. Because the heart contracts continuously, it has a particularly high energy requirement.
-
Antioxidant protection: CoQ10 can act as an antioxidant, helping protect heart cells from oxidative damage.
-
Supporting mitochondrial function: helps maintain efficient energy production within heart cells
Levels of coenzyme Q10 decrease with age:
This graph clearly shows that levels of Q0 decrease in human hearts from the age of 20 onwards.
Considering that heart issues are known to start early in life, anyone aged over 20 should consider a supplement with high dose Q10 for life long heart health.
Culd Q10 actual help with heart diseases?
CoQ10 has been studied as a supplement for several cardiovascular conditions. Some clinical trials have reported improvements in symptoms or certain measures of heart function, while other studies have found less convincing effects. Evidence is therefore not strong enough to consider CoQ10 a replacement for established heart treatments.
CoQ10 levels can also be reduced by statins, although whether taking CoQ10 supplements meaningfully improves statin-associated muscle symptoms remains uncertain.
