Coenzyme Q10: When and How to Take It?

In brief: With coenzyme Q10 there is exactly one rule that truly counts: take it with a meal that contains some fat. Because Q10 is fat-soluble, this noticeably improves absorption. Whether morning or evening, on an empty stomach or not – all of that is secondary to pairing it with fat and to consistency. The easiest approach is to tie Q10 to a fixed meal that already contains fat, such as breakfast or lunch.

No sooner do you have your Q10 capsules at home than the questions arise: Morning or evening? With or without food? Together with your other supplements or rather separately? The good news: with Q10 the answer is pleasingly straightforward. In this guide you will learn why, with coenzyme Q10, a single factor makes the difference above all – and how to fit the intake into your daily routine so that you reliably don't forget it.

The most important points at a glance

• Coenzyme Q10 is a body-produced, vitamin-like substance and fat-soluble.
• Most important is taking it with a meal containing some fat – this supports absorption.
• Whether morning or evening plays a smaller role; what matters is consistency.
• For Q10, no health claims are currently authorised in the EU; we describe it neutrally.
• If you take medication (e.g. blood thinners), clarify use with your doctor.

What coenzyme Q10 is – and why that determines how you take it

Coenzyme Q10 – also called ubiquinone – is a vitamin-like compound that your body produces itself and that occurs in almost all cells. It exists in two forms: the oxidised form ubiquinone and the reduced form ubiquinol. In foods, Q10 is found in meat, fish, nuts and vegetable oils, among others – so predominantly in fat-containing fare, which is already a hint about its nature.

Because that is precisely what is decisive in practice: Q10 is fat-soluble. From this follows the central intake tip that we will explore in a moment. The differences between the two forms are explained in detail in Coenzyme Q10: Ubiquinol, Ubiquinone and Intake.

The one factor that counts: fat

Because coenzyme Q10 is fat-soluble, the decisive point when taking it is combining it with some fat. This is easiest to achieve when you take Q10 with a meal that contains fat – for example at breakfast with nuts, yoghurt or avocado, or with a warm meal containing a little oil. Taken on an empty stomach, a fat-soluble substance tends to be absorbed less well.

We explain the fundamentals of why this is so in Bioavailability simply explained. What "on an empty stomach" actually means and when it matters at all is covered in Taking supplements on an empty stomach explained.

The reassuring news: you don't need to plan any special "fat meal" for this. As a rule, the typical components of a normal breakfast or lunch are enough – a little oil in a salad, nuts in muesli, cheese on bread or a warm dish with some fat content. All that matters is not taking the capsule on a completely empty stomach, far removed from any meal. Anyone who simply takes Q10 with one of their usual meals is already doing everything right in this respect.

Scientific classification

For coenzyme Q10, no health-related claims are currently authorised in the EU. We therefore describe Q10 factually and neutrally and make no statements about a specific health benefit. This article is solely about the practical question of when and how the intake can be arranged sensibly – that is, about timing and handling, not about promises of effect. As for the role of Q10 in energy metabolism, this is biochemically well established; more on that in Coenzyme Q10: Ubiquinol, Ubiquinone and Intake.

Morning or evening?

Whether you take coenzyme Q10 in the morning or in the evening is secondary – as long as the meal is right. Many people choose breakfast or lunch, because the intake fits well into an existing routine there and there is fat on the plate anyway. Some prefer the morning because they think of their supplements then in any case.

More important than the exact time is that you find a fixed rhythm and don't forget to take it. General considerations on timing can be found in Intake rhythm: morning or evening.

In what form you take Q10

Coenzyme Q10 is usually offered as a capsule, often already combined with a carrier oil. That is practical, because the supplement then brings part of the required fat with it, so to speak. Even so, taking it with a fat-containing meal remains a good habit, because it further favours absorption and is easy to remember. Whether capsule or softgel is the right choice is discussed in Capsule or softgel?.

Q10 is offered in the two forms ubiquinone and ubiquinol, each in different portion sizes. For the question of the right time, however, the form plays no major role – the principle "with a meal containing some fat" applies equally to both. Which form and portion size suits you is explained in detail in Coenzyme Q10: Ubiquinol, Ubiquinone and Intake.

Timing compared: what really counts?

Practical tips for everyday life

To make sure the intake works reliably, a few simple habits help:

• Tie Q10 to a fixed, fat-containing meal – that way you forget it less often.
• Place the supplement in plain sight where you eat this meal.
• Stick to a steady routine rather than irregular intakes.
• Keep to the portion stated on the product and choose an amount you can maintain over the long term.

Whether you combine Q10 with other supplements depends on the respective meal and the properties of the other preparations. Suggestions on combining are offered by Nutrients before or after eating and Combining supplements correctly. It can make sense to take several fat-soluble supplements with the same meal, since they share similar conditions for good absorption – that way you only have to remember one time point. Stick to a coherent, simple solution that works for you: the more straightforward the routine, the more likely you are to keep it up in the long run.

What you should keep in mind

Food supplements are no substitute for a healthy, balanced diet. If you take medication – such as blood thinners – you should clarify the use of coenzyme Q10 with your doctor; see also Supplements and medication. The same applies during pregnancy and breastfeeding as well as with existing illnesses. In the case of persistent complaints, medical clarification is the right course of action.

Frequently asked questions (FAQ)

When is the best time to take coenzyme Q10?

Best of all with a meal that contains some fat, because Q10 is fat-soluble and is absorbed noticeably better this way. Whether morning or midday is secondary – what matters is that there is fat on the plate and that you find a fixed rhythm. On a completely empty stomach is rather unfavourable.

Should I take Q10 in the morning or in the evening?

This plays a smaller role, as long as the meal is right. Many choose breakfast or lunch because there is fat there anyway and they think of their supplements. More important than the time of day is consistency – take Q10 at the time you can most reliably keep to.

Do I absolutely have to take Q10 with fat?

Advisable, yes, because Q10 is fat-soluble and is absorbed better with some fat. But you don't need a special fat meal – nuts in muesli, oil in a salad, cheese on bread or a warm dish with some fat content are enough. Oil-based capsules also bring part of the fat with them already.

Can I take Q10 together with other supplements?

Yes. It even makes sense to take several fat-soluble supplements with the same fat-containing meal, since they share similar conditions for good absorption. That way you only have to remember one time point. With medication such as blood thinners, clarify use with your doctor beforehand.
