Feeling tired, foggy, or low in stamina? As we age or experience periods of stress, our cells can struggle to keep up with the body’s energy demands. One key nutrient that supports natural energy production at the cellular level is CoQ10, or Coenzyme Q10.
CoQ10 is found in every cell of the body and plays a critical role in how we produce energy, manage oxidative stress, and maintain overall health. But as we get older, or experience stress, illness or medication use, our natural levels of CoQ10 decline.
So, what does CoQ10 actually do, and could it help restore your get-up-and-go? Let’s explore the science.
What Is CoQ10?
CoQ10 is a vitamin-like compound that lives inside the mitochondria, your cells' energy factories. It helps convert the food you eat into adenosine triphosphate (ATP), the energy your body uses for everything from thinking to moving to healing.
It also acts as a powerful antioxidant, defending your cells from oxidative damage caused by daily stressors like pollution, inflammation and poor sleep. These antioxidant effects have benefits for heart health, muscle recovery, brain function and more.
How CoQ10 Supports Energy and Vitality
Low energy isn't just about a lack of sleep, it can also be a signal that your cells aren’t making energy efficiently. Since CoQ10 powers the mitochondria, a deficiency can affect stamina, concentration, and even mood.
Research has shown that CoQ10 can support:
- Energy production: Clinical trials suggest CoQ10 helps support those with feelings of low energy1.
- Heart health: The heart uses more energy than any other organ, and CoQ10 supports healthy blood pressure and cardiovascular function2.
- Healthy ageing: Antioxidant activity protects cells from age-related decline, with CoQ10 playing a role in skin health, muscle strength, and cognition3.

Ubiquinol vs Ubiquinone: What’s the Difference?
There are two forms of CoQ10:
- Ubiquinone – the oxidised form, which your body needs to convert before it can use.
- Ubiquinol – the reduced, active form that your body can absorb and use immediately.
While both are useful, ubiquinol is significantly more bioavailable. Unfortunately, our ability to convert ubiquinone to ubiquinol declines as we age, making direct supplementation with ubiquinol more effective, especially after age 35.

Frequently Asked Questions
What is CoQ10 and why is it important?
CoQ10 is a compound your body uses to generate energy and protect cells from damage. It’s especially important for the heart, brain, and muscles.
Can CoQ10 help with tiredness?
Yes. CoQ10 supports energy production at the cellular level. People with low CoQ10 levels often experience fatigue, and supplementation may help restore stamina.
What is ubiquinol and why is it better?
Ubiquinol is the active form of CoQ10. It’s easier for your body to absorb and use, especially if you’re over 35 or dealing with chronic stress or health issues.
Is Napiers Japanese Energy vegan?
No, this product uses a softgel capsule that are not suitable for vegans due to the beeswax.
Is CoQ10 safe to take daily?
Yes, CoQ10 is generally safe and well-tolerated. Napiers Japanese Energy provides 100mg of Kaneka Ubiquinol per capsule, an ideal daily dose for ongoing support.
When to take CoQ10: morning or night?
Coq10 can be taken at any time of the day but it should always be taken with a meal. Taking it in the morning may be preferable to avoid any sleep issues with higher doses.
How much CoQ10 should I take?
Dosages are typically around 100mg per day, this may not be suitable for everyone so consult your health professional for more information.
Who might benefit from taking Napiers Japanese Energy?
Anyone over 35, people recovering from illness or burnout, those with demanding physical or mental workloads, and individuals wanting to support cardiovascular health or general vitality.
From powering your cells to protecting your heart, CoQ10 is a small compound with a big role in keeping you energised, resilient and well.
