CoQ10 (coenzyme Q10) is one of the most important molecules in human physiology, yet it is also one of the most misunderstood supplements on the market. Most CoQ10 supplements sold in pharmacies and health food stores contain ubiquinone, the oxidized form of CoQ10 that must be converted to ubiquinol (the active, reduced form) before the body can use it. For younger adults with healthy mitochondrial function, this conversion is efficient. For older adults, individuals taking statin medications, and those with cardiovascular conditions, the conversion is significantly impaired, making ubiquinol supplementation the only reliable way to raise active CoQ10 levels in the body.
This guide explains the biochemistry of CoQ10, why the form matters, what the clinical evidence says about ubiquinol's three Health Canada-approved uses, and why the MCT oil softgel format is essential for optimal absorption of this fat-soluble compound.

What is CoQ10 and Why Does the Body Need It?
Coenzyme Q10 (CoQ10, also called ubiquinone or ubiquinol depending on its oxidation state) is a fat-soluble, vitamin-like compound found in virtually every cell of the human body. It is particularly concentrated in tissues with the highest energy demands: the heart, liver, kidneys, and skeletal muscle.
CoQ10 serves two essential and distinct physiological roles:
Role 1: Electron Carrier in the Mitochondrial Electron Transport Chain
CoQ10 is an essential component of the mitochondrial electron transport chain (ETC), the series of protein complexes that generate the vast majority of cellular ATP. Specifically, CoQ10 shuttles electrons between Complex I (NADH dehydrogenase) and Complex II (succinate dehydrogenase) to Complex III (cytochrome bc1 complex), enabling the proton gradient that drives ATP synthase.
Without adequate CoQ10, the electron transport chain cannot function efficiently, reducing ATP production capacity. This is why CoQ10 deficiency manifests most prominently in high-energy-demand tissues: the heart (which never stops working), skeletal muscle (which has high exercise demands), and the brain.
Role 2: Fat-Soluble Antioxidant
In its reduced form (ubiquinol), CoQ10 is one of the most potent fat-soluble antioxidants in the body. It protects cell membranes and mitochondrial membranes from lipid peroxidation, regenerates vitamin E after it has been oxidized, and protects LDL cholesterol from oxidative modification (oxidized LDL is the form that initiates atherosclerotic plaque formation).
This dual role as both an energy carrier and an antioxidant makes CoQ10 unique among nutritional supplements and explains why its deficiency has such broad consequences for cardiovascular, neurological, and metabolic health.
Ubiquinol vs Ubiquinone: The Critical Difference
CoQ10 exists in two interconvertible forms that differ by two electrons and two protons:
| Property | Ubiquinol (this formula) | Ubiquinone (standard CoQ10) |
|---|---|---|
| Oxidation state | Reduced (QH2) | Oxidized (Q) |
| Active antioxidant form | Yes (directly active) | No (must be reduced to ubiquinol first) |
| Electron transport role | Accepts electrons (becomes ubiquinone) | Donates electrons (becomes ubiquinol) |
| Conversion required | No (already in active form) | Yes (must be reduced by NQO1 and other enzymes) |
| Bioavailability vs ubiquinone | Up to 8x higher in some studies | Reference standard |
| Blood level increase | Significantly greater at equivalent doses | Lower (limited by conversion capacity) |
| Effectiveness in older adults | Superior (conversion declines with age) | Reduced (conversion impaired) |
| Effectiveness with statin use | Superior (statins impair CoQ10 synthesis) | Reduced |
| Color | Milky white to pale yellow | Bright orange-yellow |
| Stability | Less stable (requires antioxidant stabilizer) | More stable |
The Conversion Problem
When ubiquinone is ingested, it must be reduced (converted) to ubiquinol by enzymes including NQO1 (NAD(P)H quinone oxidoreductase 1) and mitochondrial complex I before it can function as an antioxidant. This conversion requires:
- Functional NQO1 enzyme (activity declines with age and varies with genetic polymorphisms)
- Adequate NADH and NADPH (reducing equivalents that decline with mitochondrial dysfunction)
- Healthy mitochondrial function (which is precisely what is impaired in the conditions where CoQ10 supplementation is most needed)
The cruel irony of ubiquinone supplementation is that the individuals who need CoQ10 most (older adults, statin users, those with heart failure) are precisely those with the most impaired capacity to convert ubiquinone to ubiquinol. Ubiquinol supplementation bypasses this conversion entirely, delivering the active form directly.
Bioavailability Evidence
A randomized crossover study published in Regulatory Toxicology and Pharmacology (2009) by Langsjoen and Langsjoen found that ubiquinol supplementation produced plasma CoQ10 levels 4.7 times higher than equivalent doses of ubiquinone in healthy adults, with even greater differences in older adults and those with cardiovascular conditions. A study in Biofactors (2008) found that ubiquinol raised plasma CoQ10 levels up to 8 times higher than ubiquinone at the same dose in patients with advanced heart failure.
Why CoQ10 Declines with Age and Statin Use
Age-Related Decline
CoQ10 biosynthesis in the body follows the same mevalonate pathway as cholesterol synthesis. This pathway is highly active in youth and declines progressively with age. Research has documented the following age-related CoQ10 declines in human tissue:
| Tissue | CoQ10 at Age 20 | CoQ10 at Age 80 | Approximate Decline |
|---|---|---|---|
| Heart | Reference (100%) | ~43% of peak | 57% decline |
| Skeletal muscle | Reference (100%) | ~52% of peak | 48% decline |
| Liver | Reference (100%) | ~55% of peak | 45% decline |
| Kidney | Reference (100%) | ~65% of peak | 35% decline |
The heart experiences the greatest age-related CoQ10 decline of any tissue, which is particularly concerning given that the heart is the highest-energy-demand organ in the body, beating approximately 100,000 times per day without rest. The combination of declining CoQ10 and declining mitochondrial function with age creates a compounding energy deficit in cardiac tissue that contributes to age-related cardiovascular decline.
Statin-Induced CoQ10 Depletion
Statins (HMG-CoA reductase inhibitors, including atorvastatin, rosuvastatin, simvastatin, and others) are among the most widely prescribed medications in the world, used to lower LDL cholesterol. They work by inhibiting HMG-CoA reductase, the rate-limiting enzyme in the mevalonate pathway.
The mevalonate pathway produces not only cholesterol but also CoQ10. By inhibiting HMG-CoA reductase, statins reduce CoQ10 biosynthesis alongside cholesterol synthesis. Research has documented plasma CoQ10 reductions of 16 to 54% in patients taking various statins, with the magnitude of depletion correlating with statin dose and potency.
Statin-associated muscle symptoms (myalgia, muscle weakness, and in rare cases rhabdomyolysis) are the most common reason for statin discontinuation, affecting 5 to 29% of statin users. The mitochondrial energy deficit caused by CoQ10 depletion in skeletal muscle is a leading proposed mechanism for statin myopathy, and multiple clinical trials have investigated CoQ10 supplementation as a strategy to reduce statin-associated muscle symptoms.
Why MCT Oil Softgels Are Essential for CoQ10 Absorption
CoQ10 is highly fat-soluble and essentially insoluble in water. Its absorption from the gastrointestinal tract is therefore entirely dependent on the presence of dietary fat to stimulate bile secretion, form mixed micelles, and facilitate lymphatic uptake. Taking CoQ10 without fat dramatically reduces its absorption.
The MCT Oil Advantage
This formula uses medium-chain triglycerides (MCT) from non-GMO coconut oil as the lipid carrier within each softgel. MCT oil provides specific absorption advantages over long-chain triglycerides (LCT) for fat-soluble compounds:
- Rapid absorption: MCTs are absorbed directly into the portal circulation without requiring chylomicron formation, providing faster lipid availability for CoQ10 solubilization
- Efficient bile stimulation: MCTs stimulate bile secretion efficiently, promoting the micellar solubilization of CoQ10 in the intestinal lumen
- Consistent absorption: The MCT oil within the softgel provides a consistent lipid environment for CoQ10 dissolution regardless of the fat content of the meal consumed alongside it
- Non-GMO sourcing: The coconut oil used is non-GMO certified, consistent with Nutridom's clean-label formulation standards
Research published in the International Journal of Pharmaceutics (2009) demonstrated that CoQ10 formulated in a lipid-based delivery system (such as an MCT oil softgel) achieved significantly higher plasma CoQ10 levels compared to powder-filled capsules at equivalent doses, with the lipid formulation producing 3 to 5 times greater bioavailability.
D-Alpha Tocopherol: The Stabilizer That Protects Ubiquinol
Ubiquinol is less chemically stable than ubiquinone because its reduced state makes it susceptible to oxidation back to ubiquinone during manufacturing, storage, and digestion. This formula includes d-alpha tocopherol (natural vitamin E) as a non-medicinal ingredient specifically to stabilize the ubiquinol and prevent its oxidation.
D-alpha tocopherol is the natural, biologically active form of vitamin E (as opposed to dl-alpha tocopherol, the synthetic racemic mixture). As a fat-soluble antioxidant, it protects the ubiquinol in the softgel from oxidation by scavenging free radicals in the lipid environment of the MCT oil carrier. This stabilization ensures that the ubiquinol remains in its active reduced form from manufacturing through to absorption.
The inclusion of d-alpha tocopherol also creates a synergistic antioxidant effect: ubiquinol and vitamin E are both fat-soluble antioxidants that protect cell membranes from lipid peroxidation, and ubiquinol regenerates oxidized vitamin E back to its active form, extending the antioxidant network.
Benefit #1: Cardiovascular Health
Supporting cardiovascular health is the primary Health Canada-approved use of this product (NPN 80050346). The heart is the organ most dependent on CoQ10, and the clinical evidence for CoQ10's cardiovascular benefits is among the most extensive in nutritional medicine.
Heart Failure: The Q-SYMBIO Trial
The Q-SYMBIO trial, a randomized, double-blind, placebo-controlled study published in JACC: Heart Failure (2014) by Mortensen et al. involving 420 patients with moderate to severe heart failure, found that CoQ10 supplementation (300mg daily) for 2 years significantly reduced:
- Major adverse cardiovascular events (MACE) by 43% compared to placebo
- Cardiovascular mortality by 43%
- All-cause mortality by 42%
- Hospital admissions for heart failure
This was the first large randomized controlled trial to demonstrate a significant reduction in cardiovascular mortality with CoQ10 supplementation, and it established CoQ10 as a meaningful adjunctive therapy for heart failure management.
Blood Pressure
A meta-analysis published in the Journal of Human Hypertension (2007) analyzing 12 randomized controlled trials found that CoQ10 supplementation significantly reduced systolic blood pressure by an average of 17 mmHg and diastolic blood pressure by 10 mmHg, with effects attributed to CoQ10's role in vascular smooth muscle energy metabolism and its antioxidant protection of nitric oxide (a vasodilator that is rapidly inactivated by free radicals).
Endothelial Function
Research published in the European Heart Journal (2002) demonstrated that CoQ10 supplementation significantly improved endothelial function (measured by flow-mediated dilation) in patients with coronary artery disease, with effects attributed to reduced oxidative stress in the vascular endothelium and improved nitric oxide bioavailability.
Cardiovascular Mechanisms
- Cardiac energy production: Restores CoQ10 in cardiac mitochondria, supporting ATP production in the continuously working heart muscle
- LDL protection: Ubiquinol prevents oxidative modification of LDL cholesterol, reducing the formation of oxidized LDL that initiates atherosclerotic plaque
- Nitric oxide preservation: Antioxidant protection of nitric oxide supports vascular dilation and healthy blood pressure
- Endothelial protection: Reduces oxidative damage to the vascular endothelium, supporting arterial health
- Statin CoQ10 restoration: Replenishes CoQ10 depleted by statin medications in cardiac and skeletal muscle tissue
Benefit #2: Migraine Prophylaxis
Reducing the frequency of migraine headaches and associated symptoms (nausea and vomiting) when taken as a prophylactic is the second Health Canada-approved use of this product. This is one of the most clinically validated and least widely known applications of CoQ10.
The Mitochondrial Theory of Migraine
Migraine is increasingly understood as a disorder of neuronal energy metabolism. Research has identified mitochondrial dysfunction, impaired oxidative phosphorylation, and reduced CoQ10 levels in the brains and blood of migraine patients. The neuronal hyperexcitability that characterizes migraine may result from an energy deficit in neurons that makes them unable to maintain the ion gradients required for normal electrical stability.
CoQ10 addresses this energy deficit by restoring mitochondrial electron transport chain function in neurons, improving ATP production capacity and neuronal energy stability.
Clinical Evidence
A randomized, double-blind, placebo-controlled trial published in Neurology (2005) by Sandor et al. involving 42 migraine patients found that CoQ10 supplementation (300mg daily) for 3 months significantly reduced:
- Migraine attack frequency by 47.6% (vs 14.4% for placebo)
- Number of days with migraine headache by 36.8%
- Number of days with nausea by 44.4%
A study published in Headache (2007) by Hershey et al. found that 32.9% of pediatric migraine patients had CoQ10 levels below the reference range, and that CoQ10 supplementation significantly reduced headache frequency in deficient patients, with improvements correlating with the degree of CoQ10 level normalization.
A meta-analysis published in Nutritional Neuroscience (2019) analyzing 6 randomized controlled trials found that CoQ10 supplementation significantly reduced migraine frequency, duration, and severity compared to placebo, with effects most pronounced after 3 months of consistent supplementation.
Why Prophylaxis Requires 3 Months
The Health Canada-approved use specifies CoQ10 as a migraine prophylactic (preventive), not an acute treatment. Migraine prophylaxis with CoQ10 requires a minimum of 3 months of consistent daily supplementation before the full benefit is realized. This timeline reflects the gradual restoration of mitochondrial CoQ10 levels and the progressive improvement in neuronal energy metabolism that underlies the prophylactic effect.
Benefit #3: Antioxidant Protection
Providing antioxidants is the third Health Canada-approved use of this product. Ubiquinol is one of the most important endogenous fat-soluble antioxidants in the body, with a unique position in the antioxidant network due to its ability to be continuously regenerated by the mitochondrial electron transport chain.
Ubiquinol's Antioxidant Uniqueness
Most dietary antioxidants are consumed (oxidized) when they neutralize free radicals and must be replenished from the diet. Ubiquinol is unique because it can be regenerated from ubiquinone by the mitochondrial electron transport chain, creating a self-renewing antioxidant cycle within the cell. This regeneration capacity makes ubiquinol a particularly efficient and sustained antioxidant.
Ubiquinol's antioxidant functions include:
- Lipid peroxidation prevention: Protects cell membranes and mitochondrial membranes from oxidative damage by scavenging peroxyl radicals in the lipid bilayer
- LDL protection: Prevents oxidative modification of LDL cholesterol, reducing the formation of the atherogenic oxidized LDL form
- Vitamin E regeneration: Reduces the tocopheroxyl radical (oxidized vitamin E) back to active alpha-tocopherol, extending the fat-soluble antioxidant network
- Mitochondrial protection: Protects mitochondrial DNA and membrane proteins from oxidative damage generated by the electron transport chain
- DNA protection: Reduces oxidative DNA damage (8-OHdG) in lymphocytes and other tissues
Benefit #4: Cellular Energy and Mitochondrial Function
While not a separately listed Health Canada-approved use, cellular energy support is the fundamental mechanism underlying all of CoQ10's clinical benefits. Every cell in the body depends on mitochondrial ATP production, and CoQ10 is an irreplaceable component of the electron transport chain that generates this ATP.
Clinical Evidence for Energy and Fatigue
A randomized controlled trial published in Nutrition (2008) found that CoQ10 supplementation (300mg daily) for 8 weeks significantly reduced fatigue scores and improved physical performance in patients with chronic fatigue syndrome, with effects attributed to improved mitochondrial energy production.
Research published in the Journal of the International Society of Sports Nutrition (2008) found that CoQ10 supplementation significantly improved exercise performance, reduced exercise-induced oxidative stress, and accelerated recovery in trained athletes, with effects most pronounced in older athletes with lower baseline CoQ10 levels.
Ubiquinol and Statin Medications: The Essential Connection
The relationship between statin medications and CoQ10 depletion is one of the most clinically important and most underappreciated interactions in modern medicine. Statins are prescribed to millions of Canadians for cardiovascular risk reduction, yet they deplete the very coenzyme that is most critical for cardiac and skeletal muscle energy production.
The Statin-CoQ10 Depletion Mechanism
Statins inhibit HMG-CoA reductase, the rate-limiting enzyme in the mevalonate pathway. This pathway produces:
- Cholesterol (the intended target of statin therapy)
- CoQ10 (an unintended casualty of statin therapy)
- Dolichols (involved in protein glycosylation)
- Isoprenoids (involved in cell signaling)
By blocking the mevalonate pathway, statins reduce CoQ10 biosynthesis by 16 to 54% depending on the statin and dose. This depletion is most pronounced in cardiac and skeletal muscle tissue, precisely the tissues where CoQ10 is most critical for energy production.
Statin Myopathy and CoQ10
A randomized controlled trial published in the American Journal of Cardiology (2007) found that CoQ10 supplementation (100mg daily) significantly reduced statin-associated muscle pain intensity by 40% and muscle pain interference with daily activities by 38% compared to vitamin E placebo in patients with statin myopathy. A meta-analysis published in Atherosclerosis (2015) analyzing 6 randomized controlled trials found that CoQ10 supplementation significantly reduced statin-associated muscle symptoms, supporting its use as an adjunct to statin therapy.
Why Ubiquinol Is Preferred for Statin Users
Statin users have impaired CoQ10 biosynthesis and often have reduced mitochondrial function, which impairs the conversion of supplemental ubiquinone to ubiquinol. Ubiquinol supplementation bypasses this conversion, delivering the active form directly to tissues depleted by statin therapy. For statin users, ubiquinol is the preferred form of CoQ10 supplementation.
Ubiquinol and Fertility: The Emerging Evidence
Ubiquinol has attracted significant research interest for its potential role in supporting fertility in both women and men, driven by the high energy demands of oocyte (egg) maturation and sperm motility.
Female Fertility and Egg Quality
Oocyte maturation is one of the most energy-intensive processes in human biology, requiring massive mitochondrial ATP production for spindle formation, chromosome segregation, and fertilization. CoQ10 levels in follicular fluid (the fluid surrounding developing eggs) decline with age, paralleling the age-related decline in egg quality and fertility.
Research published in Aging Cell (2015) demonstrated that CoQ10 supplementation in aged mice significantly improved oocyte quality, mitochondrial function, and fertilization rates, with effects attributed to restored mitochondrial energy production in aging oocytes. Human observational studies have found positive correlations between follicular fluid CoQ10 levels and oocyte quality and IVF success rates.
Male Fertility and Sperm Motility
Sperm motility is driven by mitochondrial ATP production in the sperm midpiece. CoQ10 is highly concentrated in sperm mitochondria and is essential for the flagellar movement that propels sperm. A meta-analysis published in the Journal of Urology (2013) analyzing 6 randomized controlled trials found that CoQ10 supplementation significantly improved sperm motility, sperm concentration, and sperm morphology in men with idiopathic infertility.

Frequently Asked Questions
What is the difference between ubiquinol and CoQ10?
Ubiquinol and CoQ10 are the same molecule in different oxidation states. CoQ10 (coenzyme Q10) is the general name for the compound, which exists as either ubiquinone (the oxidized form) or ubiquinol (the reduced, active form). Most CoQ10 supplements contain ubiquinone, which must be converted to ubiquinol by the body before it can function as an antioxidant. Ubiquinol supplements provide the active form directly, bypassing this conversion step and achieving significantly higher plasma CoQ10 levels at equivalent doses.
Who should take ubiquinol instead of regular CoQ10?
Ubiquinol is particularly recommended for adults over 40 (whose conversion of ubiquinone to ubiquinol declines with age), individuals taking statin medications (which deplete CoQ10 and impair mitochondrial function needed for conversion), those with heart failure or cardiovascular conditions (where mitochondrial dysfunction impairs conversion), and anyone who wants maximum bioavailability from their CoQ10 supplement. Younger adults with healthy mitochondrial function can convert ubiquinone to ubiquinol efficiently, but ubiquinol remains the superior choice for anyone prioritizing bioavailability.
Can CoQ10 help with migraines?
Yes. Reducing migraine frequency is a Health Canada-approved use of this product (NPN 80050346). A randomized controlled trial published in Neurology found that CoQ10 supplementation (300mg daily) for 3 months reduced migraine attack frequency by 47.6% compared to 14.4% for placebo. CoQ10 is used as a migraine prophylactic (preventive), not an acute treatment, and requires a minimum of 3 months of consistent daily supplementation before the full benefit is realized. Individuals with migraines should consult a healthcare provider before starting CoQ10 supplementation.
Should I take CoQ10 if I am on a statin?
Statins reduce CoQ10 biosynthesis by 16 to 54% by inhibiting the mevalonate pathway that produces both cholesterol and CoQ10. This depletion is associated with statin-associated muscle symptoms (myalgia, weakness) in 5 to 29% of statin users. Clinical trials have demonstrated that CoQ10 supplementation significantly reduces statin-associated muscle pain. Statin users should discuss CoQ10 supplementation with their healthcare provider, as it is one of the most evidence-backed nutritional interventions for managing statin side effects. Ubiquinol is the preferred form for statin users due to impaired conversion capacity.
Why does this softgel contain MCT oil?
CoQ10 is fat-soluble and requires dietary fat for absorption. The MCT oil from non-GMO coconut oil within each softgel provides a built-in lipid carrier that ensures consistent CoQ10 absorption regardless of the fat content of the meal consumed alongside it. Research has demonstrated that CoQ10 formulated in a lipid-based delivery system achieves 3 to 5 times greater bioavailability compared to powder-filled capsules at equivalent doses. The MCT oil format is essential for maximizing the clinical effectiveness of ubiquinol supplementation.
How long does ubiquinol take to work?
Plasma CoQ10 levels begin rising within days of starting ubiquinol supplementation. Tissue CoQ10 levels (which are more clinically relevant) build over 2 to 4 weeks of consistent daily use. For cardiovascular and energy benefits, measurable improvements are typically reported at 4 to 8 weeks. For migraine prophylaxis, the Health Canada-approved use specifies a minimum of 3 months before the full preventive benefit is realized. Consistent daily supplementation without interruption is essential for all applications.
Is this product suitable for vegans?
No. This softgel contains bovine gelatin as the capsule shell and is not suitable for vegetarians or vegans. Individuals seeking a vegan CoQ10 supplement should look for products using plant-based capsule shells (hypromellose). The ubiquinol itself is produced through yeast fermentation and is not animal-derived, but the gelatin softgel shell is bovine-derived.
What is the best time of day to take ubiquinol?
Morning or midday with a fat-containing meal is generally preferred. CoQ10's role in mitochondrial energy production means it may have mild energizing effects that can interfere with sleep onset if taken in the evening. For doses of 200mg or more, split the dose across 2 to 3 meals throughout the day rather than taking all at once, as CoQ10 absorption is saturable and split dosing improves total daily absorption efficiency.
Conclusion
CoQ10 is not a single supplement with a single benefit. It is an essential cellular component with irreplaceable roles in mitochondrial energy production and fat-soluble antioxidant protection, and its decline with age and statin use has measurable consequences for cardiovascular health, neurological function, and cellular energy across every tissue in the body.
Ubiquinol, the active reduced form, is the only form of CoQ10 that delivers these benefits without requiring conversion by enzymes that decline with age and are impaired by the very conditions where CoQ10 supplementation is most needed. The MCT oil softgel format ensures that this fat-soluble compound is absorbed efficiently, and the d-alpha tocopherol stabilizer ensures that the ubiquinol remains in its active form from manufacturing through to absorption.
For optimal results:
- Take 1 to 3 softgels daily with fat-containing meals, split across 2 to 3 meals for doses above 100mg
- Allow 2 to 4 weeks for tissue CoQ10 levels to build to their new steady state
- For migraine prophylaxis, commit to a minimum of 3 months of consistent daily use at 300mg (3 softgels) per day
- Statin users should discuss CoQ10 supplementation with their healthcare provider
- Avoid evening dosing if you experience any sleep disruption
- Consult a healthcare provider if taking warfarin or antihypertensive medications
Active form CoQ10 with enhanced absorption: Ubiquinol 100mg — 100mg ubiquinol (active reduced form CoQ10) per softgel, MCT oil from non-GMO coconut oil for enhanced absorption, d-alpha tocopherol stabilizer, Health Canada licensed (NPN 80050346) for cardiovascular health, migraine prophylaxis, and antioxidants, non-GMO, made in Canada.
