The active, reduced form of coenzyme Q10
Kaneka Ubiquinol™, a branded ingredient with clinical documentation
Directly compared with conventional ubiquinone in a human study

Overview

Active-form coenzyme Q10 in a moderate, precise serving for your daily routine. The body converts CoQ10 between two forms: ubiquinone and ubiquinol. Ubiquinol 50 mg provides the reduced form, ubiquinol.

03Directly compared with conventional ubiquinone in a human study
04An oil-based formulation suited to fat-soluble CoQ10
05A precise serving for consistent, long-term supplementation

07One clearly defined active ingredient without a complex blend

Doctor Life / 01

Ubiquinol 50 mg

Made for your daily routine.

The formula uses Kaneka Ubiquinol™, a branded ingredient with an identified producer and production technology. Kaneka QH™ has been examined in human absorption studies and other clinical research.

Ubiquinol is fat-soluble, so the formula uses an MCT-based oil matrix. Take it with a meal, as directed.

The 50 mg version offers a lower serving of the reduced form of CoQ10. It is designed for people who value an identified ingredient source and a straightforward daily routine.

Ubiquinol 50 mg

Why does ubiquinol matter?

CoQ10 occurs in cell membranes and the mitochondrial electron transport chain, where it participates in energy-related electron transfer. The body interconverts oxidized ubiquinone and reduced ubiquinol. CoQ10 status can change with age and physiological circumstances. Kaneka Ubiquinol™ provides the reduced form directly.

Ubiquinol 50 mg

What does research say about Ubiquinol 50 mg?

Human studies of Kaneka QH™ have examined absorption, blood ubiquinol levels, and tolerability. A fatigue trial used 50 mg capsules, but participants took 100–150 mg daily, exceeding this product’s daily serving. A separate comparison in older men found a greater increase in CoQ10 status with ubiquinol than the same amount of ubiquinone. These findings do not establish the effects of one 50 mg capsule daily.

Science & sources

Understand the formula.

Particularly relevant to this version are studies of branded Kaneka QH™ and research showing that CoQ10 form matters alongside amount. These publications examine Kaneka Ubiquinol™ bioavailability, regular ubiquinol use in people experiencing fatigue, and direct comparisons with ubiquinone.

These publications concern the studied ingredients or formulas. They do not all evaluate the finished Doctor Life product, and research results do not guarantee individual outcomes.

01Study on safety and bioavailability of ubiquinol (Kaneka QH) after single and 4-week multiple oral administration to healthy volunteers

Kazunori Hosoe, Mitsuaki Kitano, Hideyuki Kishida, Hiroshi Kubo, Kenji Fujii, Mikio Kitahara

Regulatory Toxicology and Pharmacology (2007), 47(1), 19-28. DOI: 10.1016/j.yrtph.2006.07.001; PMID: 16919858.

Controlled studies in healthy volunteers evaluated the branded Kaneka QH™ ingredient. Regular daily intakes of 90, 150, or 300 mg clearly increased blood ubiquinol levels and were well tolerated. The lowest amount studied, 90 mg, was still above this product's 50 mg serving. The research documents human absorption of Kaneka Ubiquinol™ and provides useful context for the ingredient.

02Ubiquinol-10 Intake Is Effective in Relieving Mild Fatigue in Healthy Individuals

Kei Mizuno, Akihiro T. Sasaki, Kyosuke Watanabe, Yasuyoshi Watanabe

Nutrients (2020), 12(6), 1640. DOI: 10.3390/nu12061640; PMID: 32498248.

A 12-week randomized, double-blind, placebo-controlled study used softgels containing 50 mg of ubiquinol each, with participants taking a total of 100 or 150 mg daily. Even in the 100 mg group, serum ubiquinol rose severalfold, and fatigue and sleepiness after cognitive tasks improved compared with placebo. The study used the same capsule strength as this Doctor Life product, but at higher total daily intakes.

03Ubiquinol is superior to ubiquinone to enhance Coenzyme Q10 status in older men

Ying Zhang, Jin Liu, Xiao-Qiang Chen, C.-Y. Oliver Chen

Food & Function (2018), 9(11), 5653-5659. DOI: 10.1039/C8FO00971F; PMID: 30302465.

In a double-blind, randomized crossover study, older men took equal amounts of ubiquinol or ubiquinone. Ubiquinol raised total plasma CoQ10 more effectively. The findings illustrate why the active, reduced form is a meaningful formulation choice.

FAQ / Ubiquinol 50 mg

Good questions. Clear answers.

Talk to us ↗

Is 50 mg of ubiquinol enough?

The appropriate amount depends on individual needs. This product provides 50 mg of the identified ingredient Kaneka Ubiquinol™. Research on absorption supports considering the form as well as the amount, but does not guarantee a clinical benefit at this serving.

Does the form of CoQ10 matter?

Ubiquinol and ubiquinone are two forms of CoQ10. In a randomized crossover trial in older men, ubiquinol produced a greater increase in total CoQ10 than the same amount of ubiquinone. The finding applies to the preparations and population studied.

Why choose Kaneka Ubiquinol™?

Kaneka has developed production technology for stabilized reduced CoQ10. Human studies of Kaneka QH™ have examined its absorption and tolerability. Naming the ingredient makes its source and research background clear.

Have 50 mg capsules been used in clinical research?

Yes, as individual capsules. In a randomized fatigue trial, participants took two or three 50 mg softgels daily, totaling 100–150 mg. That is more than this Doctor Life product’s daily serving, so the study does not establish the effect of 50 mg daily.

Why use MCT oil?

CoQ10 is fat-soluble, and an oil matrix is a suitable carrier. This formula uses coconut MCT oil and should be taken with a meal.

Does crystallization mean the product has spoiled?

Not necessarily. The label states that the suspension may crystallize depending on temperature, which is anticipated for this formulation. Store at room temperature, no higher than 25°C.

Why do older adults consider ubiquinol?

CoQ10 metabolism can change with age. A direct comparison in older men found that ubiquinol increased total CoQ10 status more than the same amount of ubiquinone. This offers population-specific research context, without establishing a need for every older adult to supplement.
