Ubiquinol vs. Ubiquinone – Which COQ10 Is Better?

Coenzyme Q10, or CoQ10, has been important in health and wellness circles for a while now, and for good reason.

Known for its role in energy production and its antioxidant properties, CoQ10 can be essential for our cells, particularly for the heart, liver, kidneys, and other organs that need high amounts of energy to function.

But, when it comes to actually choosing a CoQ10 supplement, you’ll find it in two forms: ubiquinone and ubiquinol. So, which one should you pick? Let’s walk through the key factors to help figure out what works best.

Ubiquinone vs. Ubiquinol

Here are some key differences. Ubiquinone is the oxidized form of CoQ10. Once we consume it, our bodies convert it to ubiquinol, which is the active form, as Tod Cooperman, M.D. stated in his research.

This conversion allows it to participate in cellular energy production and provide antioxidant benefits. Ubiquinol is already in the active, reduced form, meaning it’s ready to go as soon as we take it.

As the active form, ubiquinol is what’s found in most of the CoQ10 circulating in our blood, making it potentially more effective right out of the gate.

Studies indicate that ubiquinol is 2 to 4 times better absorbed than ubiquinone, especially in older adults and those with certain health conditions. – Ubiquinol.org

CoQ10 and How It Works

This compound is naturally present in every cell in our bodies, especially in energy-intensive organs like the heart and liver.

CoQ10 fuels energy production by helping create adenosine triphosphate (ATP), the energy molecule responsible for transferring power within our cells.

On top of that, CoQ10 has antioxidant effects, protecting cells from damage caused by oxidative stress.

What’s Easier for Your Body to Use?

One of the biggest factors in choosing between ubiquinone and ubiquinol is how efficiently each one is absorbed by the body.

Ubiquinone

Ubiquinone isn’t quite as absorbable as ubiquinol, meaning our bodies need to work a little harder to convert it into the active form.

For some, particularly older adults or individuals with specific health conditions, this conversion process might not be as smooth.

As we age, our bodies tend to get less efficient at converting ubiquinone to ubiquinol, which is why many people opt for ubiquinol as they get older.

According to Johannes-Paul Fladerer’s research, certain health conditions, such as cardiovascular diseases, may impair the body’s ability to convert ubiquinone to ubiquinol, suggesting that ubiquinol supplementation could be more beneficial in these cases.

Ubiquinol

Because ubiquinol doesn’t need any conversion, it’s usually more efficiently absorbed right into the bloodstream. Research shows that ubiquinol generally has superior bioavailability compared to ubiquinone.

study by Peter H. Langsjoen and Alena M. Langsjoen involving 12 healthy volunteers found that after four weeks of supplementation, plasma CoQ10 levels increased to 4.3 µg/mL with ubiquinol, compared to 2.5 µg/mL with ubiquinone, indicating better absorption of ubiquinol.

So, if you’re looking to quickly boost CoQ10 levels, ubiquinol might have a bit of an edge here. For those who want the immediate benefits of CoQ10, especially for heart health or managing fatigue, ubiquinol could be the more effective choice.

Heart Health, Migraine Relief, and More

Both ubiquinone and ubiquinol have solid health benefits, but there are some differences depending on individual needs.

Heart Health

CoQ10 is often associated with cardiovascular benefits. A study published on Cochrane has shown that it can help improve symptoms of congestive heart failure and may even help lower blood pressure.

It’s been linked to aiding recovery for people after bypass and heart valve surgeries too. Because ubiquinol is more easily absorbed, it may offer a bit of an advantage for those specifically looking to support heart health.

Migraine Prevention

CoQ10 has also shown promise in reducing the frequency of migraines, according to Suhairul Sazali.

While both forms can be effective, ubiquinol’s easier absorption might make it a more effective preventative option for those who frequently suffer from migraines.

Fertility Boost

For anyone thinking about boosting fertility, CoQ10 has benefits for both men and women. It’s been linked to improved sperm quality and may help reduce the decline in egg number and quality that happens with age.

Since the conversion process of ubiquinone to ubiquinol may slow down as we get older, women over 35 looking to support reproductive health might find ubiquinol to be a better choice.

According to CNY Fertility research, CoQ10 supplementation can lead to significant improvements in sperm parameters, including increased sperm count, motility, and morphology. This is attributed to CoQ10’s antioxidant properties, which protect sperm cells from oxidative damage.

Dosage Considerations

Determining the right dose of CoQ10 depends on your specific needs and which form you’re taking.

General Recommendations

For adults, a typical dose of CoQ10 falls between 100 to 200 milligrams per day, as per Jillian Kubala, MS, RD. Some conditions, like certain heart issues, may call for higher doses, up to 300 or 400 milligrams.

Form-Specific Dosage

Because of its higher bioavailability, lower doses of ubiquinol can provide the same effects as higher doses of ubiquinone. In other words, you might be able to take less ubiquinol to reach the same blood levels as you would with a higher dose of ubiquinone.

If you’re new to CoQ10 or looking to target a specific health goal, consider starting with a lower dose and consulting a healthcare provider who can guide you on the optimal amount.

Safety and Side Effects

Generally, CoQ10 is considered safe with only a few mild side effects. Here’s a quick look at what to be mindful of:

  • Common Side Effects: Some people experience digestive issues such as nausea, vomiting, or diarrhea. Other side effects can include headaches, dizziness, fatigue, or skin irritation, as per drugs.com.
  • Drug Interactions: CoQ10 may interact with certain medications, especially anticoagulants like warfarin. Because of this, it’s a good idea to check with a healthcare provider before starting CoQ10, especially if you’re on other medications.

Is the Extra Price for Ubiquinol Worth It?

One difference you might notice when shopping for CoQ10 is the price. Ubiquinol is usually more expensive than ubiquinone.

Why? It comes down to the manufacturing process. Since ubiquinol has higher bioavailability, the extra cost may be worth it for those who need the absorption boost, especially older adults or those with health conditions affecting CoQ10 conversion.

If cost is a major factor, ubiquinone can still provide substantial benefits, particularly for younger individuals or those without specific absorption issues.

So, Which Form Should You Choose?

The decision between ubiquinone and ubiquinol often comes down to personal health needs, age, and lifestyle. Here are a few final thoughts to help you make the best choice:

Consider Ubiquinol if:

  • You’re over 40 and want the most absorbable form of CoQ10.
  • You’re targeting heart health or dealing with issues where immediate bioavailability might help.
  • You’re managing conditions like migraines or are focused on fertility.

Stick with Ubiquinone if:

  • You’re younger, healthy, and looking for general antioxidant and energy support.
  • Cost is a concern, and you’re looking for a more affordable option.
  • You don’t mind that your body needs to convert it into ubiquinol for it to work.

Wrapping It Up

Choosing between ubiquinone and ubiquinol doesn’t have to be overwhelming. Both forms bring valuable benefits to the table, from antioxidant protection to energy production, heart health, and more.

If you’re looking for more efficient absorption and can handle the extra cost, ubiquinol might be the better choice, especially for older adults or those with specific health needs.

For those looking for more general support, ubiquinone can still be a solid, budget-friendly choice.

Whatever you decide, CoQ10 could be a powerful addition to support your overall wellness. As always, it’s wise to consult a healthcare professional when starting any new supplement to ensure it aligns with your health goals and current regimen.
