CoQ10 (Ubiquinone vs. Ubiquinol): What Really Matters When Choosing a CoQ10 Supplement?
Ubiquinol is not automatically better than ubiquinone. And CoQ10 is about much more than the form printed on the front of the bottle.
If you've ever searched for a CoQ10 supplement, you've probably encountered the same debate:
Ubiquinone vs. ubiquinol.
One is often described as the "traditional" form.
The other is marketed as the "better," "active," or "more absorbable" form.
But CoQ10 biology is more sophisticated than a simple winner-versus-loser comparison.
CoQ10 naturally exists in two principal forms—ubiquinone and ubiquinol—and the body continuously interconverts between them as part of the CoQ10 redox cycle. At the same time, research shows that the formulation, delivery system, dose, solubility, and other characteristics of a finished product can significantly influence how much CoQ10 becomes available in the body.
So instead of asking only:
"Is this CoQ10 ubiquinone or ubiquinol?"
there is a better question:
"How well has this CoQ10 been formulated for delivery and absorption?"
Let's look at the science.
What Is CoQ10?
Coenzyme Q10 (CoQ10) is a naturally occurring, fat-soluble compound found throughout the body.
It is particularly concentrated in mitochondria—the structures inside our cells that play a central role in producing usable cellular energy.
CoQ10 participates in the mitochondrial electron transport chain, where it transfers electrons between respiratory complexes as part of oxidative phosphorylation and ATP production.
In simpler terms:
CoQ10 helps your cells produce energy.
CoQ10 also participates in antioxidant defense. Its reduced form, ubiquinol, is capable of donating electrons and plays an important role in maintaining the antioxidant capacity of cellular membranes and other lipid environments.
This is why CoQ10 is particularly interesting in tissues with high energy requirements, including the heart, skeletal muscle, brain, liver, and kidneys.
What Is CoQ10 Used For?
CoQ10 is commonly used as a nutritional supplement to support:
Cellular Energy Production
CoQ10 is an essential component of mitochondrial electron transport and therefore plays a role in ATP production.
Antioxidant Protection
CoQ10 participates in the body's antioxidant network, particularly through the reduced ubiquinol form.
Maintaining CoQ10 Availability
The body's endogenous production of CoQ10 can change with age and certain physiological or clinical circumstances, which is one reason CoQ10 supplementation has been extensively studied.
It is important, however, to distinguish biological function and nutritional support from claims that a supplement can diagnose, treat, cure, or prevent a disease.
Ubiquinone vs. Ubiquinol: What's the Difference?
CoQ10 exists primarily in two redox states.
Ubiquinone
Ubiquinone is the oxidized form of CoQ10.
It is capable of accepting electrons.
Ubiquinol
Ubiquinol is the reduced form of CoQ10.
It is capable of donating electrons and contributes importantly to CoQ10's antioxidant activity.
But here's the part that often gets left out of supplement marketing:
These are not two unrelated versions of CoQ10.
They are two interconvertible redox states within the same biochemical system.
Think of it as a cycle:
UBIQUINONE ⇄ UBIQUINOL
The direction of that cycle changes as CoQ10 participates in electron transfer and redox reactions.
The 2024 scientific review of the ubiquinone–ubiquinol redox cycle describes continual interconversion between the two forms as a fundamental part of normal CoQ10 function.
Can Your Body Convert Ubiquinone Into Ubiquinol?
Yes.
Your body has enzymatic systems that participate in the reduction of ubiquinone to ubiquinol.
Ubiquinol can also be oxidized back to ubiquinone.
This isn't an unusual process.
It is part of normal CoQ10 biology.
Inside mitochondria, ubiquinone accepts electrons and becomes reduced to ubiquinol. Later in the electron transport chain, ubiquinol transfers electrons and becomes oxidized again.
This continuous cycling is one of the reasons it is misleading to describe ubiquinone as simply an "inactive" form.
What Happens to Ubiquinone After You Take It?
Suppose your supplement contains ubiquinone.
After ingestion, the CoQ10 has to pass through the digestive system and be absorbed.
Once it enters circulation, the CoQ10 measured in blood is predominantly in the reduced ubiquinol state.
Human pharmacokinetic research has observed that circulating CoQ10 is largely present as ubiquinol, even when supplementation begins with ubiquinone.
That doesn't mean the supplement somehow "becomes a completely different nutrient."
It means the body is doing what it normally does:
interconverting CoQ10 between its oxidized and reduced states.
Does Aging Make It Harder to Convert Ubiquinone to Ubiquinol?
You may have heard another common claim:
"As you get older, your body can no longer efficiently convert ubiquinone into ubiquinol."
This claim is one reason ubiquinol is often recommended for older adults.
There is a real scientific question behind it—but the popular version of the claim is much stronger than the evidence supports.
What We Know About Aging and CoQ10
CoQ10 levels and endogenous CoQ10 synthesis tend to decline with age.
That is well documented.
However, a decline in total CoQ10 levels is not the same thing as losing the ability to convert ubiquinone into ubiquinol.
The available human evidence does not establish that people simply reach a particular age—such as 40, 50, or 60—and then lose the ability to reduce ubiquinone to ubiquinol.
In fact, older adults have been shown to absorb and increase circulating CoQ10 after supplementation with ubiquinone.
A randomized crossover study in 21 healthy adults aged 65–74 compared 100 mg of three formulations: a water-soluble CoQ10 formulation, ubiquinol, and ubiquinone.
The researchers found that the CoQ10 circulating in blood appeared predominantly as ubiquinol regardless of whether participants consumed ubiquinone or ubiquinol.
That's an important finding.
It means we should be careful about saying that older adults cannot convert ubiquinone into ubiquinol.
But Does Ubiquinol Ever Perform Better in Older People?
Yes—and this is where the story becomes more nuanced.
A 2018 randomized crossover trial studied 10 older men who took 200 mg/day of either ubiquinol or ubiquinone for two weeks.
Ubiquinol produced a significantly greater increase in plasma total CoQ10 in that particular study.
However, the response was not uniform: six participants responded better to ubiquinol, while two responded better to ubiquinone.
The study was also very small and did not demonstrate a meaningful change in several cellular or oxidative-stress measures during the short intervention.
So the study provides evidence that a particular ubiquinol formulation may produce greater circulating CoQ10 exposure than a particular ubiquinone formulation in some older adults.
It does not prove that aging causes the body to lose its ability to convert ubiquinone into ubiquinol.
Those are two very different claims.
The More Accurate Way to Say It
Instead of:
"Older people cannot convert ubiquinone efficiently, so they need ubiquinol."
A scientifically safer statement is:
"CoQ10 production declines with age, and some studies in older adults have found higher circulating CoQ10 exposure with particular ubiquinol formulations compared with particular ubiquinone formulations. However, older adults can still convert and absorb ubiquinone, and the evidence does not establish a universal age-related conversion failure."
That distinction matters.
Do You Need Twice as Much Ubiquinone to Equal 100 mg of Ubiquinol?
Another claim you may encounter is:
"You need 200 mg of ubiquinone to equal 100 mg of ubiquinol."
There is no established scientific 2:1 conversion rule like this.
The problem is that dose and bioavailability are not the same thing.
If you take 100 mg of ubiquinone and 100 mg of ubiquinol, you cannot automatically predict that one will produce exactly half or twice the blood exposure of the other.
Why?
Because CoQ10 absorption varies considerably between formulations.
A human study comparing seven different 100-mg CoQ10 formulations found significant differences in bioavailability.
Interestingly, the best-performing products included both a ubiquinone formulation and a ubiquinol formulation.
Another study in adults aged 65–74 compared three 100-mg formulations and found that the water-soluble formulation had 2.4-fold greater bioavailability than the standard ubiquinone comparator, while the ubiquinol formulation showed a 1.7-fold increase that did not reach statistical significance.
Importantly, the absorbed CoQ10 appeared predominantly as ubiquinol regardless of the form consumed.
This illustrates why a blanket rule such as:
100 mg ubiquinol = 200 mg ubiquinone
doesn't work.
Which Ubiquinone Are We Talking About?
A conventional crystalline ubiquinone?
An oil-based ubiquinone?
A solubilized ubiquinone?
A liposomal ubiquinone?
A cyclodextrin-complexed ubiquinone?
These are not necessarily equivalent formulations.
The delivery system can change the amount of CoQ10 that reaches circulation.
So rather than trying to calculate a universal "ubiquinol equivalent," evaluate the specific product and its formulation.
What This Means When Comparing CoQ10 Products
This is why a simple comparison such as:
"100 mg ubiquinol is better than 100 mg ubiquinone."
doesn't tell the whole story.
A better comparison asks:
- What form is being used?
- How much CoQ10 is provided?
- What delivery technology is used?
- Has that specific formulation been studied in humans?
- What comparator was used?
- What does the bioavailability data actually show?
This is particularly important when comparing products that use specialized delivery technologies such as liposomal CoQ10 or MicroActive® CoQ10.
The molecular form is one variable.
The formulation is another.
And the two should not be treated as if they are the same thing.
So, Is Ubiquinol Better Than Ubiquinone?
Here's where we need nuance.
The answer is:
Not universally.
But we also shouldn't say:
"The form doesn't matter at all."
That would go too far in the opposite direction.
There are studies showing that some ubiquinol formulations achieve greater blood CoQ10 exposure than particular ubiquinone formulations.
For example, a 2026 randomized crossover pilot study involving a specific cocrystal ubiquinol formulation found substantially higher systemic exposure than the particular ubiquinone reference formulation used in that trial.
However, it was a small study involving only 12 healthy adults, and the result should not be interpreted as proof that every ubiquinol product is superior to every ubiquinone product.
Other studies tell a more complicated story.
A study comparing seven different 100-mg CoQ10 formulations found significant differences in bioavailability and showed that formulation characteristics, including the matrix used to deliver CoQ10 could substantially influence absorption.
Interestingly, the two best-performing formulations in that study were a ubiquinone softgel and a ubiquinol softgel.
Another study in healthy older adults found that a water-soluble CoQ10 formulation had significantly higher bioavailability than standard ubiquinone, while the ubiquinol formulation did not show a statistically significant increase versus the standard comparator.
The researchers also found that absorbed CoQ10 appeared predominantly as ubiquinol regardless of whether the supplement had been consumed as ubiquinone or ubiquinol.
So the evidence doesn't support a simple:
Ubiquinol = automatically superior.
Instead, it supports a much more useful conclusion:
The molecular form matters, but the formulation and delivery system matter too.
Why Does CoQ10 Need a Good Delivery System?
This is one of the most important things to understand about CoQ10.
CoQ10 is highly lipophilic and has very low water solubility.
That makes oral absorption challenging.
Imagine putting CoQ10 into a capsule.
The amount printed on the Supplement Facts panel tells you how much CoQ10 is present.
But it doesn't tell you how efficiently that CoQ10 will move through the digestive system and become available for absorption.
For oral CoQ10 to be useful, several steps have to occur:
Ingestion → dispersion → digestion → intestinal absorption → transport into circulation → tissue availability
The formulation can influence several of those steps.
A major review of CoQ10 bioavailability emphasizes the importance of crystal dispersion and formulation characteristics, while newer research continues to investigate technologies such as liposomes, micelles, nanoemulsions, solid dispersions, nanoparticles, and other delivery systems.
Why Two CoQ10 Products With the Same Dose May Not Behave the Same
Imagine two bottles.
Both say:
CoQ10 — 100 mg
It would be tempting to assume they are equivalent.
But they may use completely different:
- Carrier oils
- Solubilization systems
- Excipients
- Particle characteristics
- Delivery technologies
- Manufacturing processes
And those differences can affect absorption.
In the seven-formulation human study mentioned earlier, all products contained 100 mg of CoQ10, yet bioavailability differed significantly between formulations.
Hence, you may find two CoQ10 products using Kaneka™ ubiquinol with noticeably different prices. You may even find ubiquinone sourced from the same raw-material supplier but sold at different price points.
Why? Because the raw ingredient is only part of the equation.
That's a critical lesson:
The number on the label is important—but it isn't the whole story.
What Is Liposomal CoQ10?
One approach to improving CoQ10 delivery is liposomal technology.
Liposomes are microscopic structures formed from phospholipids.
Because CoQ10 is fat-soluble, it can be incorporated into lipid-based delivery structures designed to improve its dispersion and interaction with the gastrointestinal environment.
The goal is to improve the amount of CoQ10 that becomes available for absorption.
Research into CoQ10 delivery systems has identified liposomes as one of several technologies being investigated to overcome CoQ10's poor water solubility and bioavailability limitations.
But there is an important distinction:
Liposomal does not automatically mean better.
The specific liposomal formulation matters.
A 2018 human study comparing three commercial CoQ10 preparations found substantial variability between formulations and did not find the tested liposomal product to be superior.
On the other hand, a 2025 randomized, double-blind, placebo-controlled crossover trial involving 18 healthy adults found that the specific liposomal CoQ10 formulation studied produced higher Cmax and AUC than unformulated CoQ10.
So the evidence teaches us something important:
Don't judge a delivery system by its name alone.
Judge the actual formulation and evidence behind it.
What Is MicroActive® CoQ10?
Now we come to another interesting approach:
MicroActive® CoQ10.
MicroActive® is a ubiquinone-based CoQ10 delivery technology that uses a patented beta-cyclodextrin complex.
This is different from liposomal delivery.
Instead of using phospholipid vesicles, the MicroActive® process complexes CoQ10 with beta-cyclodextrin.
According to the ingredient manufacturer, each CoQ10 molecule is complexed with two beta-cyclodextrin molecules. The complex is designed to improve water dispersibility and facilitate transport through the digestive system.
The result is a water-dispersible CoQ10 complex designed to provide sustained release.
In simple terms:
Liposomal CoQ10
CoQ10 + phospholipid-based delivery
MicroActive® CoQ10
CoQ10 + beta-cyclodextrin complex
They are different technologies designed to address a similar problem:
How do we improve the delivery of a highly lipophilic molecule?
What Does the Human Research on MicroActive® Show?
This is where MicroActive® becomes particularly interesting.
A published human study by Madhavi and Kagan evaluated a sustained-release CoQ10-beta-cyclodextrin complex against crystalline CoQ10 and an oil-solubilized CoQ10 softgel.
The first phase included five subjects in a 24-hour crossover design using a 180-mg dose.
A second phase compared the MicroActive® complex with the solubilized product using 60 mg daily, including a 21-day accumulation period.
The researchers reported:
- Sustained release from the MicroActive® complex
- 3.7-fold greater bioavailability than the crystalline comparator in the first study
- More uniform absorption compared with the solubilized comparator
- At 21 days, all subjects in the MicroActive® accumulation group had at least doubled their plasma CoQ10 levels
However, there is an important caveat.
This was a small human study, and the MicroActive® technology is supported in large part by research associated with its developer/manufacturer.
Therefore, we should describe these results accurately as findings from studies of the specific MicroActive® formulation, rather than extrapolating them to every ubiquinone product.
That's an important distinction when evaluating branded ingredients.
MicroActive® vs. Liposomal CoQ10
Now we can see why the conversation becomes more interesting.
These aren't simply different names for the same thing.
| Technology | CoQ10 form | Delivery approach |
|---|---|---|
| Conventional crystalline CoQ10 | Ubiquinone | Basic crystalline form |
| Ubiquinol formulations | Ubiquinol | Various carrier/solubilization systems |
| Liposomal CoQ10 | Ubiquinone or other form depending on product | Phospholipid-based liposomes |
| MicroActive® CoQ10 | Ubiquinone | Beta-cyclodextrin complex + sustained release |
The important point is that the chemical form and the delivery technology are two separate considerations.
You can have:
Ubiquinone + sophisticated delivery
or
Ubiquinol + sophisticated delivery
or
Ubiquinone + basic formulation
And those products should not automatically be assumed to have identical absorption.
So What Should You Actually Look For in a CoQ10 Supplement?
Instead of getting caught up in one word on the label, evaluate the entire formulation.
1. The Dose
How much CoQ10 are you actually getting per serving?
A 30-mg product and a 250-mg product are obviously very different products.
Dose matters.
2. The CoQ10 Form
Is it:
Ubiquinone?
Ubiquinol?
Both are legitimate forms within CoQ10 biology.
The form deserves consideration—but shouldn't be the only criterion.
3. The Delivery System
Ask:
How has the manufacturer addressed CoQ10's poor water solubility and absorption challenges?
Is it:
- Oil-based?
- Solubilized?
- Liposomal?
- Cyclodextrin-complexed?
- Micronized?
- Another specialized delivery system?
The answer can matter.
4. The Evidence
Don't stop at:
"Advanced absorption technology."
Ask:
Has the actual formulation been studied in humans?
And:
What was it compared against?
This is especially important because bioavailability claims can vary considerably between products.
5. Stability
CoQ10 is sensitive to environmental conditions, and formulation and storage conditions can influence product stability.
A sophisticated delivery system doesn't help if the finished product isn't properly manufactured, packaged, and stored.
6. Quality and Transparency
Look beyond the marketing on the front label.
Look at:
- The Supplement Facts panel
- Ingredient sourcing
- Manufacturing standards
- Testing
- Excipients
- Delivery technology
- Stability
- Clinical evidence
Evaluate the whole formula.
Codeage Liposomal CoQ10 Max: Putting This Into Practice
Now let's apply the framework to Codeage Liposomal CoQ10 Max.
This product uses ubiquinone, rather than ubiquinol.
But that doesn't tell us everything about the product.
Each daily serving provides:
250 mg of CoQ10
The CoQ10 is delivered using a phospholipid-based liposomal delivery system designed to support dispersion and absorption.
The formula also includes vitamin E in the form of:
- d-alpha tocopherol
- Gamma tocopherol
- Delta tocopherol
- Beta tocopherol
It is designed as a one-capsule daily serving and provides a 60-day supply per bottle.
The formula is also positioned as:
- Vegan
- Non-GMO
- Dairy-free
- Soy-free
- Gluten-free
And it is:
manufactured in a cGMP-certified facility in the USA using globally sourced ingredients.
And importantly, Codeage Liposomal CoQ10 Max is listed by NSF International under NSF/ANSI Standard 173 for Dietary Supplements, providing an additional layer of independent third-party product verification.
So if someone asks:
"Why did you choose a ubiquinone CoQ10 instead of ubiquinol?"
The answer isn't:
"Because ubiquinone is better."
And it shouldn't be:
"Because ubiquinol doesn't matter."
The more scientifically appropriate answer is:
"Because the form is only one part of the formulation. This product combines 250 mg of ubiquinone with a phospholipid-based liposomal delivery system designed to support absorption."
That's a much more meaningful way to evaluate the product.
The Bigger Picture: CoQ10 Is More Than Ubiquinone vs. Ubiquinol
The supplement industry naturally gravitates toward simple comparisons.
Ubiquinol = superior.
Ubiquinone = inferior.
But the science is more nuanced.
Your body naturally uses both forms.
It continuously interconverts them as part of the CoQ10 redox cycle.
At the same time, the amount of CoQ10 that becomes available to your body can be influenced by the formulation and delivery system.
Human research has repeatedly demonstrated differences in CoQ10 bioavailability between formulations containing similar nominal doses.
This is why delivery technologies such as liposomal CoQ10 and MicroActive® CoQ10 deserve attention.
They represent different strategies for addressing CoQ10's fundamental delivery challenge.
The real question isn't:
"Which word sounds better?"
It's:
"How well is this particular CoQ10 product formulated?"
A Simple CoQ10 Buying Checklist
Before buying your next CoQ10 supplement, ask these six questions:
1. What form is it?
Ubiquinone or ubiquinol?
2. How much does it provide?
Check the actual CoQ10 dose.
3. How is it delivered?
Liposomal, solubilized, oil-based, cyclodextrin-complexed, or another system?
4. Has the formulation been studied?
Look for human bioavailability data.
5. How stable is the product?
Formulation and packaging matter.
6. Who made it and how is it tested?
Quality control matters just as much as the ingredient name.
Frequently Asked Questions
Is ubiquinol better than ubiquinone?
Not universally.
Ubiquinol is the reduced form of CoQ10, while ubiquinone is the oxidized form. The body naturally interconverts between them. Some specific ubiquinol formulations have demonstrated higher bioavailability than particular ubiquinone formulations, but research also shows that formulation characteristics can strongly influence absorption.
Can the body convert ubiquinone to ubiquinol?
Yes.
The body continuously interconverts ubiquinone and ubiquinol as part of the CoQ10 redox cycle.
Does ubiquinone become ubiquinol in the body?
A substantial proportion of circulating CoQ10 is present as ubiquinol, even when supplementation begins with ubiquinone.
Does age make it harder to convert ubiquinone to ubiquinol?
There is not enough evidence to say that aging causes a universal loss of the ability to convert ubiquinone to ubiquinol.
CoQ10 production does decline with age, and some studies in older adults have found greater circulating CoQ10 exposure from particular ubiquinol formulations. However, older adults can still absorb ubiquinone and convert it to circulating ubiquinol.
Do I need twice as much ubiquinone as ubiquinol?
No established 2:1 rule exists.
You cannot scientifically say that 200 mg of ubiquinone is equivalent to 100 mg of ubiquinol across all products.
Bioavailability depends on the specific formulation, dose, delivery system, and other product characteristics.
What is CoQ10 used for?
CoQ10 participates in mitochondrial electron transport and cellular energy production and contributes to antioxidant defense. It is also used as a dietary supplement in research involving several areas of health, although evidence for specific clinical applications varies.
Why is CoQ10 difficult to absorb?
CoQ10 is highly lipophilic and poorly water-soluble. These properties can limit its oral bioavailability, which is why different delivery and formulation technologies have been developed.
Does liposomal CoQ10 absorb better?
It can, depending on the specific formulation.
A 2025 randomized crossover study found higher absorption from the specific liposomal CoQ10 formulation tested compared with unformulated CoQ10. However, another human study found that a different liposomal preparation did not perform better than the other preparations tested.
This demonstrates why the specific formulation matters more than the word "liposomal" alone.
What is MicroActive® CoQ10?
MicroActive® CoQ10 is a branded ubiquinone ingredient that uses a beta-cyclodextrin complex designed to improve water dispersibility and provide sustained release. Human research on the specific formulation has reported greater bioavailability than crystalline CoQ10.
Is MicroActive® CoQ10 liposomal?
No.
MicroActive® uses beta-cyclodextrin complexation, whereas liposomal CoQ10 uses phospholipid-based vesicles.
They are different delivery technologies.
Is MicroActive® better than liposomal CoQ10?
There is not enough evidence to make a universal statement that one technology is superior to the other.
The correct comparison should be between specific finished formulations, doses, delivery systems, and human bioavailability data.
Should CoQ10 be taken with food?
Because conventional CoQ10 is fat-soluble, taking it with food, particularly a meal containing some fat, can support absorption. However, follow the directions for the specific formulation because specialized delivery systems may have different instructions.
The Bottom Line
Don't choose CoQ10 based on one word on the label.
Ubiquinone matters.
Ubiquinol matters.
But so do:
Dose.
Delivery.
Formulation.
Stability.
Quality.
Bioavailability.
Your body naturally interconverts ubiquinone and ubiquinol.
So rather than treating them as two competing substances where one must automatically win, look at the entire formulation.
Because the most useful question isn't:
"Is this ubiquinone or ubiquinol?"
It's:
"What is the quality of this CoQ10, how much am I getting, and how intelligently has it been formulated for delivery?"
That is the bigger CoQ10 conversation.
