Your body makes coenzyme Q10 — but from around the age of twenty, production steadily declines. So the number on a supplement label matters far less than how much your body can actually absorb.
Why absorption is the real question
Your body makes coenzyme Q10 (CoQ10), and from around the age of twenty, the amount it produces begins a slow, steady decline. That's part of why CoQ10 supplements are so popular, particularly for heart and cellular energy support. But here's the catch that most labels don't mention: CoQ10 is one of the most difficult nutrients to absorb, so the milligram number printed on the bottle matters far less than how much of it actually makes it into your bloodstream. A high-dose supplement that's poorly absorbed can deliver less than a smaller, well-formulated one. Understanding how CoQ10 absorption really works — and cutting through some of the marketing myths around it — helps you choose and use a supplement that genuinely delivers, rather than one that mostly passes straight through you.
The absorption challenge
CoQ10 is a large, fat-loving (lipophilic) molecule with very poor water solubility, and this makes it inherently hard for the gut to take up.
Reviews note that the oral absorption efficiency of CoQ10 is very low — on the order of just a few percent — owing to its large molecular size, poor water solubility and limited solubility even in fats, which is precisely why advanced delivery formulations have been developed to improve it (CoQ10 bioavailability review).
Ubiquinol vs ubiquinone: the honest answer
You'll often see CoQ10 marketed in two forms — ubiquinone (the oxidised form) and ubiquinol (the reduced form) — with ubiquinol frequently promoted as far superior. The honest reality is more nuanced.
Bioavailability research indicates that intestinal absorption of CoQ10 is highly variable between individuals and largely independent of which form is taken, with studies finding that around 90% of CoQ10 circulating in the blood ends up in the ubiquinol form regardless of whether ubiquinone or ubiquinol was consumed — because the body readily interconverts the two (CoQ10 bioavailability overview).
So the ubiquinol-versus-ubiquinone debate is less decisive than the marketing suggests: your body converts between the two forms, and what circulates ends up much the same either way. What matters more is the two things marketing often glosses over: formulation (how well the CoQ10 is dispersed and delivered) and how you take it. Because CoQ10 is fat-soluble, taking it with a meal containing fat significantly improves absorption — this simple step often matters more than the form on the label. Absorption also varies a lot from person to person. The practical message is refreshingly honest: don't get lost in ubiquinol-versus-ubiquinone claims; focus on a well-designed formulation, take it with food, and be consistent.
This is worth dwelling on, because the ubiquinol-versus-ubiquinone debate is a good example of how supplement marketing can steer attention toward the wrong question. It's an appealing story: a "reduced, active" form that sounds more advanced and more bioavailable, often carrying a premium price. And there's a kernel of truth — ubiquinol is indeed the form that does the antioxidant work in the body. But the leap from "it's the active form" to "therefore you absorb it far better" doesn't hold up well under scrutiny, precisely because your body is perfectly capable of converting ordinary ubiquinone into ubiquinol during and after absorption. So whichever form you swallow, what your cells ultimately work with looks remarkably similar. Meanwhile, the factors that genuinely make a large difference to how much CoQ10 reaches your blood — the quality of the formulation and whether you take it with fat — get comparatively little airtime because they're less catchy selling points. Understanding this frees you from anxiety about picking the "right" form and lets you focus on what actually matters. It's a useful principle for supplements generally: the headline claim on the front of the bottle is often less important than the unglamorous practicalities of delivery, dosing and how you take it.
Making your CoQ10 count
Given all this, how do you get the most from CoQ10? First, take it with your largest, fattiest meal — this is one of the simplest and most effective ways to improve absorption of any CoQ10 product. Second, look for a formulation designed to overcome CoQ10's poor solubility, rather than just a big milligram number. Liposomal delivery is one such approach: it wraps the CoQ10 in tiny spheres made of the same kind of material as our cell membranes, aiming to improve its dispersion and uptake — and our Liposomal CoQ10 capsules use this delivery method for exactly that reason. Third, be consistent, since CoQ10 builds up gradually. And keep expectations grounded, including about absorption itself: better absorption means more CoQ10 reaching your bloodstream, which is not the same thing as a proven health benefit. CoQ10 is a supportive nutrient, valued especially for heart and cellular energy, but it's a complement to a healthy lifestyle and proper medical care, not a replacement. If you take medication — particularly blood thinners like warfarin, which CoQ10 can interact with — or have a heart condition, check with your doctor first, and never stop prescribed treatment.

Frequently asked questions
Why is CoQ10 hard to absorb?
CoQ10 is a large, fat-loving molecule with very poor water solubility, so the gut absorbs only a small percentage of an oral dose — and absorption varies a lot between people. This is why the form of delivery and taking it correctly matter more than the milligram number on the label.
Is ubiquinol better than ubiquinone?
Less than the marketing suggests. Your body readily converts between the two forms, and research shows around 90% of circulating CoQ10 ends up as ubiquinol regardless of which you take. Absorption is highly variable and largely independent of form — formulation and taking it with fat matter more than the ubiquinol-versus-ubiquinone question.
How can I absorb CoQ10 better?
Take it with your largest, fattiest meal, since CoQ10 is fat-soluble — this simple step often matters more than the form. Choose a formulation designed to improve its dispersion (such as liposomal delivery) rather than just a high milligram number, and be consistent, as CoQ10 builds up gradually.
Should I take CoQ10 with food?
Yes — definitely. CoQ10 is fat-soluble, so taking it with a meal containing fat significantly improves how much you absorb. Taking it on an empty stomach wastes much of the dose. This is one of the easiest and most effective ways to get more from any CoQ10 supplement.
Does the milligram number on the label matter?
Less than you'd think. Because CoQ10 is so poorly absorbed, a high-dose product that's poorly formulated can deliver less than a smaller, well-formulated one taken with food. Focus on the quality of the formulation and how you take it, not just the headline milligram figure.
Is CoQ10 safe to take?
CoQ10 is generally very well tolerated. The main caution is that it may interact with blood-thinning medication such as warfarin, so check with your doctor if you take one, have a heart condition, or take other medication. It's a supportive nutrient — not a replacement for prescribed treatment.
Well-absorbed CoQ10
Our Liposomal CoQ10 capsules use liposomal delivery to improve dispersion and uptake of this notoriously hard-to-absorb, fat-soluble nutrient.
