How Much CoQ10 Do You Need, and in What Form?

Medically reviewed by Dr. Cheryl Burdette, ND · September 30, 2026

Is there a recommended daily amount of CoQ10?

No. CoQ10 has no established Daily Value, which is a specific regulatory status rather than an oversight. It means no reference intake has been set for it the way one has been set for, say, vitamin C.

You can see this on any CoQ10 label. In the Supplement Facts panel, the %DV column shows a dagger symbol beside CoQ10 and a footnote reading “Daily Value not established.” That is the same on every brand’s panel, and it is why you cannot evaluate a CoQ10 product by looking for a percentage.

It also means the useful comparison is not against a government reference number. It is against the amounts used in research, which vary with what a study is looking at.

What amounts does research use?

A typical diet supplies only a few milligrams of CoQ10 a day — around 5 mg. Human studies have commonly used far more, generally between 100 and 300 mg a day.²

Two things are worth knowing about that range. First, it sits well above what any ordinary diet delivers, which is the practical reason CoQ10 exists as a supplement category at all. Second, within the range studied, a larger amount generally does raise blood levels further: in one comparison, 200 mg raised them more than 100 mg did. The gut can only take up so much at one time, though, so the increase is not unlimited.² A higher amount is not automatically a better one, and depending on why you are taking CoQ10, it may simply not be necessary.

What about delivery systems and phytosomes?

Some formulas use a delivery system intended to improve absorption rather than simply raising the milligram count. A phytosome is one such approach: the CoQ10 is bound with a phospholipid to make it easier for the body to take up.

Formulation genuinely changes results. Pharmacokinetic studies, which track how much of a dose reaches the blood over time, show that different CoQ10 products can produce very different blood levels from the same milligram amount, and that the same product can vary from one person to the next.²

So judge these the way you would judge any absorption claim — by asking what it is being compared against and whether that comparison is published. An absorption claim without a stated comparator is not telling you much.

When should you take CoQ10?

With a meal that contains some fat. This is the single most actionable thing on this page.

Because CoQ10 is fat-soluble, taking it on an empty stomach means absorbing less of it regardless of how many milligrams are on the label. Consistency matters too: pick a meal you eat reliably and attach it to that, rather than aiming for a particular time of day.

Can you take too much CoQ10?

CoQ10 is a compound your body already produces and handles routinely. Reported side effects at supplemental amounts are typically mild and digestive.

That said, no upper intake level has been formally established, “well tolerated” is not the same as “unlimited,” and CoQ10 is one of the supplements with documented relevance to prescription medication. If you take any prescription drug — and particularly if you take a blood thinner or a statin — the amount and the timing are worth raising with the clinician who prescribed it rather than settling from a label.

How much CoQ10 is in Humann products?

Humann’s current CoQ10 formulas differ in amount, form and format, so it is worth stating each rather than generalizing:

Two are chews and one is a softgel. Like any CoQ10 product, each is best taken alongside a meal that contains some fat.

What to check on a CoQ10 label

• The milligram amount per serving, not per bottle or per capsule count.
• The serving size — some products count a serving as two units.
• Whether the form is named, and whether any absorption claim states what it is compared against.
• Whether the directions say to take it with food. If they do not, take it with food anyway.
• Third-party testing, if purity and potency verification matters to you.

Common questions

Why is there no %DV for CoQ10?

Because no Daily Value has been established for it. Supplement Facts panels mark this with a dagger and the footnote “Daily Value not established.” It is a regulatory status, not a statement about whether the nutrient matters.

Is ubiquinol better than ubiquinone?

Not as a rule. The body converts between the two forms, and most clinical research has used ubiquinone. Comparisons between them are mixed and often turn on how a product is formulated rather than on which form it contains. Whichever you choose, taking it with a meal that contains fat helps absorption.

Should I take CoQ10 in the morning or at night?

Attach it to a meal containing fat rather than to a clock time, and keep it consistent. Which meal matters less than whether you actually take it.

Can you get enough CoQ10 from food?

Not at the amounts used in research. A typical diet supplies only a few milligrams a day. Your own body’s production is the main source, and supplemental amounts sit well above dietary intake.

Is more CoQ10 always better?

Not necessarily. Blood levels generally rise with the amount taken, but the gut can only absorb so much at one time, and a higher amount may simply not be necessary for your purposes. Amount, formulation and whether you take it with food all interact.
