Should heart failure patients be prescribed Q10?
Patients with heart failure benefit from supplementation with Q10, concludes the largest and most carefully conducted meta-study to date. Q10 improves heart function and survival.
All trials were in patients with heart failure. During a contraction, the patients' heart muscle was no longer able to pump enough blood into the vascular system during contraction. In the trials, researchers had studied the effect of Q10. We have written about some trials before.
In most trials the subjects received only Q10, but there were also a few trials in which the researchers gave combinations of Q10 with L-carnitine or selenium.
The duration of administration varied from 4 weeks to 2 years, the dose from 24 to 400 milligrams per day. We are, of course, just ignorant journalists, but we believe that average supplement users should take no more than 200 milligrams of Q10.
Supplementation reduced the chance that the subjects had to be hospitalized because of their heart failure by 40 percent, the figure above shows.
Q10 increased the amount of blood the heart could pump into the body when it contracted. The effect was not overwhelming, but it was statistically significant.
However, the studies they used for their meta-analysis contained too many methodological flaws to base a decision of this magnitude on. The reserachers believe that there should first be a good and thoroughly designed trial.
