Coenzyme Q10

What are the benefits of Coenzyme Q10, FAQ and dosage

Discovered in 1957 by Fredrick L. Crane and his colleagues, Coenzyme Q10 chemical structure was first reported by Karl Folkers and his coworkers at Merck. A decade or so later, it was observed that CoQ10 defficiency was associated with the heart disease. After clinical trials in the 1980s, it was established that CoQ10 plays important roles in cellular energy production and antioxidant protection.

Since then, there has been an abundance of information on the topic of Coenzyme Q10 and its many benefits, ranging from anti-aging to the heart health protection. So, do you think CoQ10 is right for you? Read on!

While there are many health benefits from Coenzyme Q10, its main claim is to be effective in cellular energy production, providing antioxidant protection, anti-aging, and benefiting the heart health function. CoQ10 plays a key role in ATP - the universal energy molecule.

Benefits of Coenzyme Q10

There are many health claims associated with CoQ10. We examine here the most relevant ones and offer our assessment. This should give you a start to reserach it more and make up your own mind.

A Rich Source of Anti-oxidants

Coenzyme Q10 (CoQ10), also known as Ubiquinone, has been documented as a rich source of anti-oxidants. In much of the research and articles I've read, Coenzyme Q10 is consistently thought to act in much the same way that vitamin E does. In fact, CoQ10 has been found in many studies to be much more effective than vitamin E in lowering cholesterol and creating an optimum environment for the cells to create energy.

Other strong antioxidant protection qualities include:

  • the reduction in risk of heart disease and 
  • regulation of blood pressure. 

[Coenzyme Q10 is also known as Ubiquinone and Ubiquinol. Both of these CoQ10 forms are available as separate supplements. Ubiquinone CoQ10 is more common and yellowish, available since 1990, while Ubiquinol CoQ10 is more raw, whiteish and more expensive, available since 2007.]

Stimulates the Immune System

CoQ10 has also been shown to be an important component in the function of the immune system. It both inhibits bacteria as well as increases immune function. It also increases white blood cell production. In many cases when the body is deficient in CoQ10 (which becomes more common as we age) the immune system becomes compromised. This is where supplementation can often counteract this.

Anti-aging Qualities

Studies also suggest there is possible anti-aging effects in CoQ10. It has been shown to slow the aging process through its antioxidant protection. Anti-oxidants, as we know, prevent "free radicals" damage - the instability of cells which causes them to mutate unnecessarily, creating everything from sun damage to cancer. CoQ10 has also been noted to increase endurance during exercise, living up to its name as an energy supplement. It is currently also being used as a therapy and reversal for Alzheimer's disease.

Benefits the Heart Health

Coenzyme Q10 depletion has also been linked to hypertension - high blood pressure. Therefore supplementation of CoQ10 is currently being used as a natural remedy to decrease blood pressure. It is also recommended in reducing the risk of atherosclerosis (hardening of the arteries) and for prevention of the oxidation of LDL cholesterol which causes plaque.

Helps with Oral Health

Like green tea, Coenzyme Q10 has been thought to promote oral health. According to many studies, CoQ10 is supposed to slow or arrest periodontal disease. It also protects the gums and heals damage from gingivitis as well as protects teeth from cavities.

Supports Weight Loss

Obesity can lead to a decrease in the production of CoQ10. Therefore, in many of the studies I found, supplementation of CoQ10 was given to both to patients suffering from obesity and patients looking to manage weight.

The Bad News

What's the bad news? Not much. There doesn't seem to be any documented toxicity from supplementing with CoQ10. However, if you are pregnant or a nursing mom it would be best not to take this supplement as the long terms effects have not been recorded. Some reports suggest CoQ10 will decrease the effectiveness of Warfarin - a blood thinner, but there is no evidence to suggest it is decidedly so. Finally, the dosage should not exceed 200 mg per day as this - in some cases - has been shown to cause diarrhea and nausea.

Other FAQ's About CoQ10

How much CoQ10 is enough to reap the benefits? For best results, according to the literature this author consulted, 30-60mg capsule up to 3 times per day is a safe dosage when taken with meals. When choosing a supplement, it is important to be sure the capsule is in CoQ10's natural form, which is dark bright yellow in color.

In Summary

Once again, in this author's opinion, I would suggest Coenzyme Q10 as being well worth your consideration. Do your homework, however. As with any change in your healthcare program, always consult your healthcare practitioner. If you are on any other medications be sure to talk to your doctor or pharmacist about the possibility of interaction. Conduct your own research project. Below are some great resources that will help get you started on getting more information about Ubiquinone, an all-important energy supplement.
