In heart failure, the heart muscle weakens and doesn’t pump enough blood to serve the body. Coenzyme Q10 is a powerful antioxidant that occurs naturally in nearly every cell in the body, and helps convert food into cellular energy. Doctors said CoQ10 may help improve blood flow in heart failure but several earlier studies were inconclusive.
Here, researchers reviewed 13 placebo-controlled trials involving 395 participants with heart failure. Dosages in the studies ranged from 60 mg to 300 mg of CoQ10 per day, and lasted from two to 24 weeks.
Combining results from all the studies, doctors found that CoQ10 increased by
3.7 percent the volume of blood flowing through the large heart chamber to the body. Doctors concluded that, in heart failure, CoQ10 moderately improves the ability of the heart to pump blood.
