CoQ10 for Blood Pressure; Heart Health

Coenzyme Q10 (CoQ10)

Coenzyme Q10 (CoQ10) is a naturally occurring substance found in the mitochondria—the energy producing part of a human cell.  It is also an antioxidant, helping to rid the body of harmful substances (toxins, etc).

CoQ10 levels tend to drop as one ages.  Studies have also shown that low CoQ10 levels are correlated with certain health problems, such as high cholesterol and congestive heart failure (though it isn’t clear if this is cause or effect).

CoQ10 shows the most promise as a treatment for mild to moderate hypertension (high blood pressure).  Research indicates CoQ10 supplementation can cause small decreases in blood pressure (systolic and possibly diastolic).   CoQ10 may also allow those with high blood pressure to take a lower dosage of conventional hypertension medications. 

There’s some evidence that CoQ10 can benefit those with heart problems.  One study found those who supplemented with CoQ10 after a heart attack were less likely to experience another heart attack and less likely to die from a heart attack.  Researchers believe CoQ10 helps with heart issues by improving energy production in cells, preventing clots, and acting as an antioxidant.  Further studies need to be done in order to establish CoQ10’s value for heart health.

CoQ10 is free of side effects since it is a naturally occurring compound in the body.  But you would need to ask your doctor about possible interactions with other medications (especially warfarin and other blood thinners).

The recommended dose for CoQ10 supplementation is 30 – 200 mg daily.  It is a fat soluble, so it CoQ10 should be taken with a meal containing fat.

My final thoughts:

I take a CoQ10 supplement every day.  I don’t have hypertension or heart problems, but both run in my family.  CoQ10 seems to be an all-around worthwhile supplement.  I’m especially interested in it’s ability to control blood pressure without side effects.  You can click the image below if you want to buy it online.
