Side Effects of COQ10

Are there side effects of COQ10? After all, many nutrients and supplements that have a great deal of health benefits can also have adverse effects.

Overall, COQ10 appears to be a very safe nutrient...and, in fact, our bodies produce it naturally, even though certain people can become deficient in it.

In addition, we tend to produce less and less of it as we age, which is why a great many people are looking into supplementation with COQ10 and wisely educating themselves on and potential side effects of COQ10.

Although there is no RDA (Recommended Daily Allowance) set for COQ10, most people who use it take a dosage between 30mg to 100mg per day.

People with certain health conditions, such as angina, congestive heart failure, parkinson's, or kidney failure often take more -- 150 mg to 200 mg per day or even higher.

Even doses of up to 400 mg per day are used without much reports of any significant COQ10 side effects. However, this doesn't mean you should take a high dosage. More is not always better.

Moreover, you should always consult your physician before taking supplements of any kind.

Side effects of COQ10, though rare, range from: dizziness, nausea, insomnia, and headaches.

People who suffer from diabetes should watch their blood sugar carefully when using COQ10 because their glucose levels can drop while using this supplement.

Moreover, people on warfarin (a prescription blood thinner) need to consult with their physician to have their blood test results monitored frequently if they intend to use COQ10 because COQ10 side effects can interact/interfere with the functioning of this drug.
