Five CoQ10 supplements compared by label
EDITOR'S PICKS 2026
What It Is

What is CoQ10?

CoQ10 (coenzyme Q10) is a compound your cells use to make energy. Your body makes its own, and supplements list it as ubiquinone or ubiquinol.

Who It's For

Who takes CoQ10?

Cellular energy

CoQ10 is part of how your cells make energy. CoQ10+ supports cellular energy production.

Everyday energy

For adults who want a simple once-a-day routine for everyday energy support.

Cell membranes

CoQ10 is found in cell membranes throughout the body. CoQ10+ supports healthy cell membranes.

Adults over 40

Your body makes its own CoQ10, and research reviews report lower levels with age.

What to Look For

Five Things to Check on the Label.

01/05

Amount per serving

Look at the milligrams per capsule and how many capsules make a serving. Published studies have used a range of daily amounts, often 100 to 300 mg.

200mg · One Capsule
02/05

Form named on the label

CoQ10 comes as ubiquinone or ubiquinol. A clear label tells you which one is in the bottle. Ubiquinone is the form with the longer research record.

Ubiquinone
03/05

Vegetable capsule

CoQ10 comes in gelatin softgels with an oil base or in vegetable capsules. If you avoid animal ingredients, check the capsule line under Other Ingredients.

No Gelatin · No Soy Oil
04/05

Single ingredient

One active ingredient, with its full amount on the panel. Some formulas add a second active, such as vitamin E or black pepper extract.

CoQ10 Only
05/05

Third-party tested

Outside testing checks that what is on the label is what is in the capsule. Look for a named test program, seal or certificate of analysis.

Lab tested
Ubiquinol or ubiquinone?

Ubiquinol is the reduced form and ubiquinone the oxidized form, and the body converts between the two. Ubiquinone has the longer research record. Whichever you choose, compare milligrams per serving.

The Research

Why amount and form are the details we compare.

CoQ10 has been studied for decades for its role in how cells make energy. When we compare products, we look at the amount per serving, the form named on the label, the capsule and outside testing.

Published CoQ10 studies have used a range of daily amounts, often 100 to 300 mg, and ubiquinone is the form with the longer research record. Lopez-Lluch et al. (2019), writing in Nutrition, compared CoQ10 supplements and reported that absorption depends on the carrier lipids and on how the CoQ10 is dissolved. A vegetable capsule holds the same compound without a gelatin shell.
