Facts About CoQ10

Coenzyme Q10 (CoQ10) is a fat soluble compound also known as ubiquinone, which derives its name from the word “ubiquitous” because it is found in all living cells.14  Many varieties of Coenzyme Q are found in nature and numbers are used to distinguish between them. Coenzyme Q10 is a ubiquinone that is found in humans and other mammals.15  Food sources of CoQ10 are primarily animal products, with an average daily intake of 3-5 milligrams in the Western diet.16

The human body can synthesize CoQ10, but only with the help of several essential vitamins.  Therefore poor nutrition, and inadequate vitamin intake, can lead to impaired CoQ10 synthesis and low CoQ10 levels.*4  Other causes of low CoQ10 levels may be poor heart health or poor gum health,17,18 drug interactions,19 heavy exercise,20 and extreme tissue needs.*4 Additionally, CoQ10 levels in the body naturally decline with age,21 and are often low in people experiencing poor health.*22,23

Coenzyme Q10 is available in both a dry, powdered form and in an oil-based suspension.  Most,44,45 though not all,5 studies indicate that oil-based CoQ10 provides enhanced intestinal absorption and bioavailability.*


CoQ10 plays an essential role in the production of adenosine triphosphate (ATP), which provides the body with energy.*7  Because all cellular activity requires an ample supply of ATP, CoQ10 is especially important to those cells that are the most metabolically active, such as those in the heart, muscle,  gastrointestinal tract, reproductive tissues, and the immune system.*3,9,14

 CoQ10 supports the cardiovascular system and promotes heart health.* Its beneficial antioxidant effects inhibit lipid peroxidation of low-density lipoprotein (LDL) cholesterol.*4,5  Oxidation of LDL cholesterol is a contributing factor for poor heart health. CoQ10 also provides oxidative protection to the proteins and DNA of the energy-producing mitochondria that are active in the heart and other tissues.*8

Human studies indicate that supplementing with 90 mg/day or more of CoQ10 produces a stronger heart muscle (a positive inotropic action),*24,6 and 100-120 mg/day protects the heart from the effects of decreased blood supply.*25,26  Studies also suggest that 30 mg of CoQ10 per day helps maintain the heart’s natural rhythm,*27  as well as to help maintain healthy blood pressure.*2

CoQ10 contributes to healthy carbohydrate metabolism probably due to its role in the electron transport chain.*7 This has also been shown to be an important factor in maintaining healthy blood sugar levels.*28 

Strenuous physical activity lowers plasma levels of CoQ10,*20 therefore CoQ10 supplementation can help recover normal energy production in overworked muscles.*29,30  Some measurements of exercise physiology in both athletes and non-athletes can be improved by taking 60-100 mg/day of CoQ10 supplements, according to some,31,32,33,34 though not all, 35 studies.* However, highly-trained endurance athletes do not appear to consistently benefit from CoQ10 supplementation.*36,37,38

Human sperm fluid (semen) is rich in CoQ10, which appears to provide crucial antioxidant protection,12 and plays a role in optimum sperm function.*13 Preliminary research suggests that CoQ10 supplementation can increase sperm count and motility39 and supports optimum male fertility.*40

People with poor gum health have been found to have low levels of coenzyme Q.*18,41 Controlled research has determined that supplementation with 60-100 mg/day of CoQ10 helps maintain healthy gums and provides protection against damage to gums.*4,42,43

Nature’s Life® pure CoQ10 is from OptiPure® brand, a high quality import containing NO milk products, wheat, corn, soy or eggs.  CoQ10 supplements are available in water-based capsules and tablets or oil-based softgel caps.  Because CoQ10 is a fat-soluble nutrient, absorption is best when taken with food that contains fat, especially when ingesting the water-based forms.

Coenzyme Q10 is usually well-tolerated and no serious adverse effects have been reported in up to six years of continuous supplementation with 100 mg/day.*46  Individuals using CoQ10 in large doses (100 mg/day or more) for heart health should consult their health care practitioner before stopping or lowering the dose.47  Safety during pregnancy and lactation has not been investigated.7  Some prescription drugs, specifically including some used to lower cholesterol and blood pressure and to treat depression, may inhibit the body’s synthesis of CoQ10.*  In most cases, adequate CoQ10 levels can be maintained by taking supplemental CoQ10.*3
