A High Strength And Bioavailable Source of CoQ10
At the heart of the formula is 100 mg of Kaneka Ubiquinol — the active, bio-identical form of Coenzyme Q10 (CoQ10) used by every cell in your body. Japanese Energy features Ubiquinol Coenzyme Q10, which is more readily absorbed by the body compared to standard oxidised CoQ10 (Ubiquinone). Kaneka Ubiquinol is bio-identical to the CoQ10 naturally produced in the human body and is manufactured in Japan using a fermentation-based process. Ideal for those seeking a quality CoQ10 supplement to support their daily energy needs.
2
Streamlined routine: one smart daily capsule
In a world where people are taking more supplements than ever, Japanese Energy keeps things simple. It’s just one capsule a day, delivering high-strength, highly bioavailable CoQ10. No complicated timings, no handfuls of pills. Most people find they can drop several weaker energy or antioxidant supplements and streamline their routine, without losing out on the support they’re looking for.
3
Vital for high-demand organs and everyday recovery
CoQ10 isn’t just about feeling less tired — it’s central to the energy systems of your heart, brain and muscles. These tissues demand a lot, and when CoQ10 levels drop (as they tend to with age or stress) performance and recovery suffer. Napiers Japanese Energy supports those high-demand systems so you can bounce back faster and maintain strength under pressure. What you’ll notice: fewer days where you feel drained, quicker recovery after exertion, greater resilience when life asks more of you.
4
Optimised absorption & bioavailability
Most CoQ10 supplements use the oxidised form (ubiquinone), which the body must convert before it becomes usable. Napiers Japanese Energy features ubiquinol — naturally fermented in Japan, ready for your body to use. This means higher uptake, less wastage and stronger results. What you’ll notice: a difference you can feel without needing to increase your dose dramatically.
5
Crafted by herbalists, backed by heritage
From our Edinburgh beginnings in 1860, Napiers motto has been: tried, tested, trusted. Napiers Japanese Energy carries that same spirit. We use Kaneka Ubiquinol, one of the worlds most researched CoQ10 ingredients. What you’ll notice: the confidence that you’re using a supplement grounded in herbalist experience and modern evidence rather than a generic mass-market product.

Targets Key Systems of Your Energy & Vitality
Your body doesn’t produce energy in one place. It draws on several interconnected systems that must work in harmony. Napiers Japanese Energy supports these systems at a foundational, cellular level — helping you feel steadier, clearer and more resilient throughout the day.
Cellular Energy Production
Mitochondria are your cells’ energy centres. They rely on CoQ10 to convert nutrients into usable energy, helping you stay balanced and energised day to day.
Heart & Cardiovascular Function
Your heart demands more energy than any other organ. Adequate CoQ10 levels help it maintain healthy rhythm, circulation and long-term vitality.
Muscle Performance & Recovery
Movement, physical exertion and daily tension increase the body’s need for CoQ10. When levels are low, muscles tire faster and recover more slowly.
Age-Related Energy Decline
Natural CoQ10 levels decline over time, often contributing to reduced vitality. Maintaining healthy levels is important for supporting energy as you age.

CoQ10 plays a key role in the body's natural energy production pathways. This product supports energy metabolism, though individual responses may vary.
Why choose Japanese-made Ubiquinol?
Kaneka Ubiquinol is widely used in Japan and internationally for its purity and high absorption. It is produced through natural fermentation for superior quality.
Can I take this with other supplements?
Yes, although you should check with a healthcare professional or a herbalist if you’re taking medication or managing a health condition.
