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

Coenzyme Q10 in its reduced form. The body continually converts CoQ10 between two forms: ubiquinone and ubiquinol. Ubiquinol participates in this cycle of oxidation and reduction and is the main form of CoQ10 circulating in blood plasma.

Doctor Life / 01

Ubiquinol 100 mg, 30 capsules

Made for your daily routine.

The formula uses Kaneka Ubiquinol™, a branded ingredient from Japan’s Kaneka. Its source and production technology are identified, and it has been used in clinical research.

Ubiquinol is fat-soluble, so we placed it in an MCT-based oil matrix. The capsule helps protect this sensitive reduced form from oxygen exposure, which can convert ubiquinol to ubiquinone.

Randomized trials using 100 mg of ubiquinol—the amount in this product—have reported increased blood CoQ10 levels and examined fatigue after cognitive tasks and endothelial function. A crossover study in older men found a greater increase in CoQ10 status with ubiquinol than the same amount of ubiquinone. These findings concern the formulations studied, not this finished product.

Ubiquinol 100 mg, 30 capsules

Why does ubiquinol matter?

Coenzyme Q10 is found in cell membranes and the mitochondrial electron transport chain, where it helps transfer electrons. It exists as oxidized ubiquinone and reduced ubiquinol. Ubiquinol also participates in the body’s fat-soluble antioxidant system. Some human comparisons, particularly in older adults, have found greater increases in blood CoQ10 with ubiquinol than ubiquinone, although formulation also matters.

Ubiquinol 100 mg, 30 capsules

What does research say about Ubiquinol 100 mg?

A randomized trial using 100 mg of Kaneka QH™ daily reported improved flow-mediated dilation, an endothelial function measure, and increased plasma CoQ10. In another 12-week trial, 100 mg of ubiquinol increased serum levels approximately three- to fourfold and was associated with less reported fatigue and sleepiness after cognitive tasks than placebo. A direct comparison in older men favored ubiquinol for increasing CoQ10 status. The studies did not test this finished Doctor Life product.

Science & sources

Understand the formula.

Especially relevant to this formula are studies using 100 mg of ubiquinol, the amount in one Doctor Life capsule, and studies directly comparing ubiquinol with conventional ubiquinone. These publications examine practical outcomes and the relative performance of the active, reduced form of CoQ10.

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.

01Ubiquinol Ameliorates Endothelial Dysfunction in Subjects with Mild-to-Moderate Dyslipidemia: A Randomized Clinical Trial

Jacopo Sabbatinelli, Patrick Orlando, Roberta Galeazzi et al.

Nutrients (2020), 12(4), 1098. DOI: 10.3390/nu12041098; PMID: 32326664.

An eight-week randomized, double-blind study evaluated Kaneka QH™ at 100 or 200 mg daily in people with mild-to-moderate dyslipidemia and impaired endothelial function. The 100 mg group, matching the ubiquinol amount in this Doctor Life product, showed a significant improvement in flow-mediated dilation compared with placebo, alongside a clear increase in plasma CoQ10.

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.

In a 12-week double-blind, placebo-controlled study, healthy adults with mild fatigue received 100 or 150 mg of ubiquinol daily. In the 100 mg group, matching the product's daily serving, serum ubiquinol rose approximately three- to fourfold. Participants also reported less fatigue and sleepiness after cognitive tasks than those receiving placebo.

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 200 mg of ubiquinol or 200 mg of ubiquinone for two weeks. Ubiquinol significantly increased total plasma CoQ10, while ubiquinone did not produce a significant increase. The findings explain the interest in reduced CoQ10, particularly for older adults.

FAQ / Ubiquinol 100 mg, 30 capsules

Good questions. Clear answers.

Talk to us ↗

Does the form of CoQ10 matter?

Ubiquinol and ubiquinone are two forms of coenzyme Q10. In a randomized crossover trial in older men, ubiquinol increased total plasma CoQ10 more than the same amount of ubiquinone. The finding concerns the preparations and population studied; delivery formulation also matters.

Has 100 mg of ubiquinol been studied?

Yes. Several randomized human trials used 100 mg daily. One Kaneka QH™ trial examined flow-mediated dilation and plasma CoQ10; another found increased serum ubiquinol and less reported fatigue and sleepiness after cognitive tasks. The finished Doctor Life product was not tested.

Why choose Kaneka Ubiquinol™?

Kaneka developed patented technology for producing ubiquinol for supplements. The ingredient has an identifiable source and has been used in clinical studies, including a 100 mg Kaneka QH™ trial of endothelial function. Naming the source makes it easier to understand which ingredient is used.

Why is ubiquinol in oil?

Coenzyme Q10 is fat-soluble. The oil matrix suits that property and helps protect the reduced ubiquinol form within the capsule. Take it with a meal, as directed on the label.

Should I notice an effect after one capsule?

Do not expect an immediate effect from a single serving. Clinical studies examined regular use over several weeks. In a 12-week trial, serum ubiquinol was already higher after four weeks and remained elevated during continued use.

Does crystallization mean the product has spoiled?

The label notes that the suspension may crystallize depending on temperature; this is anticipated for the formulation. Store at room temperature, no higher than 25°C, and follow the manufacturer’s storage directions.

Is ubiquinol particularly relevant to older adults?

A direct comparison in older men found that ubiquinol increased total plasma CoQ10 more than the same amount of ubiquinone. This provides research relevant to that population, but does not establish that one form is best for every older adult.
