I am happy with "doctor's Best, High Absorption CO Q10" because I found the the quality is as good as the more expensive ones. I will definitely buy again from iHerb and will recommend to others too. Maybe, since living in Malta, need to order a little earlier due to delivery time.

CoQ10, with Bioperine

13 people found the following review helpful

Posted by Reviewer2324732 on Jul 29, 2011

Many years ago I was diagnosed with a heart beat irregularity, called "premature atrial contractions" (PACs). Subsequent tests showed some "premature ventricular contractions" (PVCs) also. These were usually evident to some degree and I noticed periods where the frequency increased from about one a minute to one about every 8 seconds. I had been taking 60 mg of CoQ10 per day, but when we happened to buy a bottle of 100 mg capsules, after a few weeks, I noticed the frequency of PACs and PVCs noticeably decreased. Since then I have begun taking one of these capsules twice a day, and the issue of PACs and PVCs has reduced to the point where I don't even think about them anymore. I believe this improvement is directly related to the higher dosage of CoQ10.

Very important if you are taking statins!

CoQ10 is a compound that occurs naturally within the cells of the human body. Its main role is to support energy production in our cells and act as an anti-oxidant. As I said, this conditionally essential nutrient is really important if you are taking statins, since these inhibit CoQ10 production in the body, and/or if you have inherited mitochondrial disease, but you might also give it a shot if you are suffering from one of the following: Periodontal disease; Heart problems; Fibromyalgia; Chronic Fatigue Syndrome; Migraines; Depression; Hypertension; Huntington’s disease; Parkinson’s disease..and possibly much more, since as an anti-oxidant, it has potential to be helpful in every disease where oxidative stress is increased. There is much more research that has to be done on some of the mentioned health ailments though. As we get older, we are becoming less effective in converting CoQ10 from this form, ubiquinone, to reduced and active form, ubiquinol, so if you are 50+, consider taking active form of CoQ10. Me and my family have only good experiences with this brand, so I definitely recommend this product to you. Price is great too!
