    Intro to CoQ10


    Introduction to CoQ10
    -info from Michael Murray, N.D.
    CoQ10 is an essential component of the mitochondria - the energy producing unit of the cells of our body. CoQ10 is involved in the manufacture of ATP, the energy currency of all body processes. A good analogy for CoQ10's role is similar to the role of a spark plug in a car engine. Just as the car cannot function without that initial spark, the human body cannot function without CoQ10.

    Although CoQ10 can be synthesized within the body, there are a number of circumstances where the body simply does not make sufficient amounts. As the heart is one of the most metabolically active tissues in the body, a CoQ10 deficiency affects the heart the most and can lead to serious problems there. Deficiency could be a result of impaired CoQ10 synthesis due to nutritional deficiencies, a genetic or acquired defect in CoQ10 synthesis, or increased tissue needs. Examples of diseases that require increased tissue levels of CoQ10 are primarily heart and vascular diseases including high cholesterol levels and high blood pressure. In addition, people over the age of 50 may have increased CoQ10 requirements as CoQ10 levels are known to decline with advancing age.

    What are the principal uses of CoQ10?
    CoQ10 supplementation is used primarily in the treatment of cardiovascular diseases such as elevated cholesterol levels, high blood pressure, congestive heart failure, cardiomyopathy, mitral valve prolapse, coronary artery bypass surgery, and angina. Considerable scientific studies have validated these uses.2-4 CoQ10 has also been shown to be helpful in diabetes; periodontal disease; immune deficiency; cancer; as a weight-loss aid; and muscular dystrophy. Since the response of CoQ10 can take time, a noticeable improvement might not occur until 8 or more weeks after therapy is begun.

    How does CoQ10 improve heart function?
    By improving energy production in the heart muscle and by acting as an antioxidant.5,6 The therapeutic use of CoQ10 in cardiovascular disease has been clearly documented in both animal studies and human trials. CoQ10 deficiency is common in patients with heart disease. Biopsy results from heart tissue in patients with various cardiovascular diseases showed a CoQ10 deficiency in 50-75% of cases.6 Correction of a CoQ10 deficiency can often produce dramatic clinical results in patients with any kind of heart disease.7-11

    Can CoQ10 lower blood pressure?
    Yes. CoQ10 deficiency has been shown to be present in 39% of patients with high blood pressure. This finding alone suggests a need for CoQ10 supplementation. However, CoQ10 appears to provide benefits beyond correction of a deficiency. In several studies CoQ10 has actually been shown to lower blood pressure in patients with hypertension.12-14 The effect of CoQ10 on blood pressure is usually not seen until after 4-12 weeks of therapy. Typical reductions in both systolic and diastolic blood pressure with CoQ10 therapy in patients with high blood pressure are in the 10% range.

    How does CoQ10 boost the immune system?
    Tissues and cells involved with immune function are highly energy-dependent and therefore require an adequate supply of CoQ10 for optimal function. Several studies have documented an immune-enhancing effect of CoQ and a benefit in cancer patients.18-20 Also, CoQ10 should definitely be used by cancer patients taking any chemotherapy drug that is associated with heart toxicity (e.g., adriamycin, athralines, etc.).21

    What is the best form of CoQ10?
    Coenzyme Q10 is available primarily in tablet or capsules. Based on bioavailability studies, the best preparations appear to be soft-gelatin capsules that contain CoQ10 in an oil base or in a soluble form.23-25 In order to further enhance absorption, CoQ10 should be taken with food.

    How much CoQ10 should I take?
    While the usual dosage recommendation for CoQ10 is 50 to 150 mg/day, there are a lot of variables to consider when trying determining whether this amount is really ideal. First of all, as mentioned above it appears that the ultimate judge of whether CoQ10 is going to be effective is whether or not CoQ10 blood levels rise above 2.5 mcg/ml and are maintained at this level for a prolonged period. Since the normal blood level for CoQ10 is roughly 1 mcg/ml, it is often difficult to achieve this therapeutic blood level especially if using poorly absorbed forms of CoQ10. .


    Is CoQ10 safe?
    Coenzyme Q10 is very safe and there have been no serious adverse effects ever reported even with long-term use. Because safety during pregnancy and lactation has not been proven, CoQ10 should not be used during these times unless the potential clinical benefit (as determined by a physician) outweighs the risks.

    Does CoQ10 interact with any drugs?
    There are no known adverse interactions between CoQ10 and any drug or nutrient. While there are no adverse drug interactions many drugs adversely affect CoQ10 levels or CoQ10 is able to reduce the side effects of the drug. In addition to adriamycin (discussed above), CoQ10 supplementation has been shown to counteract some of the adverse effects of certain cholesterol-lowering, beta-blocker, and psychotrophic drugs.

    The drugs lovastatin (Mevacor), pravastin (Pravachol), atorvastatin (Lipitor) and simvastatine (Zocor) are widely used to lower blood cholesterol levels. They work by inhibiting the enzyme (HMG CoA reductase) that is required in the manufacture of cholesterol in the liver. Unfortunately, in doing so these drugs also block the manufacture of other substances necessary for body functions including CoQ10. Supplementing CoQ10 (50 mg per day) is necessary to prevent the depletion of CoQ10 in body tissues while on these drugs.29

    Hey guys... look into Idebenone as well. Idebenone doesn't shift oxidant-modality like Co-Q10 can. 1fast carries it in bulk[25g for $32.50]

    Now has a 400mg Co-Q10 gelcap. I take one in the am, and one before bed. You can get the Now gels from a variety of sources for under $50[400mg x 60 gelcaps/24g]

    Good thread, Size.

    My energy levels are vastly improved since adding 50 mgs of CoQ10 ed. Love it. Wish it would come down in price so I can up the dose.

    Costco has some pretty good deals on CoQ as well as a lot of other supps.

    Why 400mg or 800mg? The article says 50-150mg.

    100 mg does the job for me. It's even more important for those who take Red Rice yeast

    So you guys use this primarily for an all day energy boost?

    Ive been looking for a natural source, since overcoming depression. ALCAR worked well but it tastes foul lol.

    May give this a try.

    Vitamin World has it for great prices in their clearance bins. I usually take 100 mg/day to keep BP down, but I've found 400 mg. doses there for even better prices than I'd normally pay for even 50 mg.

    I bought up a ton for future use and will just bump up to the 400 dose when I'm on my next ph/ps cycle, for addes BP support.

    ...Too much of anything can be bad for you. More is not always better.

    Valid rule of thumb, but I'm guessing it wouldn't be commonly sold in a 400 mg. dose if it were considered unsafe at that dose. I've never read that 400 mg. was considered too high a dose for anyone, but if anyone finds contradictory evidence, please post.
