Search "ubiquinol" and you'll quickly land on "CoQ10", "coenzyme Q10", "ubiquinone" and even "Q10". It's one of the most common points of confusion in the supplement aisle, and it's the reason questions like "is ubiquinol the same as CoQ10?" get asked hundreds of times a month in Australia. This guide explains the difference in plain language, so you can read a label with confidence.
What Is CoQ10 | The Short Version
Coenzyme Q10 (CoQ10) is a naturally occurring, vitamin-like compound found in almost every cell in the body. It's especially concentrated in organs that use a lot of energy, and it plays a role in the processes cells use to produce energy. Your body makes its own CoQ10, and small amounts come from foods such as oily fish, organ meats, nuts and whole grains.
"CoQ10" is the umbrella name. Under that umbrella, there are two main forms.
Ubiquinone vs Ubiquinol | The Two Forms of CoQ10
- Ubiquinone is the oxidised form of CoQ10. It's the form found in most standard "CoQ10" supplements and it has been used for decades.
- Ubiquinol is the reduced form of CoQ10. In the body, CoQ10 continually shifts between these two forms as part of normal cellular processes.
So, is ubiquinol the same as CoQ10? Ubiquinol is CoQ10, just in its reduced form. When a label simply says "CoQ10" or "coenzyme Q10", it usually means ubiquinone. When it says "ubiquinol", it means the reduced form.
| Ubiquinone | Ubiquinol | |
|---|---|---|
| Form | Oxidised CoQ10 | Reduced CoQ10 |
| Common label wording | "CoQ10", "Coenzyme Q10", "Q10" | "Ubiquinol", "Reduced CoQ10" |
| Typical price | Usually lower | Usually higher |
| Stability in manufacturing | Very stable | More sensitive, so it needs careful formulation |
| Often chosen by | Budget-focused shoppers | People who specifically want the reduced form, often adults 40+ |
Why Do Some People Choose Ubiquinol?
People who choose ubiquinol usually do so because they want CoQ10 in the reduced form from the start, rather than relying on their body to convert it. It's a popular choice among adults over 40 and people with active lifestyles, and among anyone who has read up on CoQ10 and wants to be specific about the form they take.
That said, ubiquinone remains a widely used, well-established option. The "right" form depends on your preferences, budget and advice from your healthcare professional.
How to Read a CoQ10 Label | 4 Things to Check
- The form: look for the word "ubiquinol" or "ubiquinone". If it just says "CoQ10", it's almost always ubiquinone.
- Amount per serve: check the milligrams per serving, not per bottle.
- Servings per bottle: divide the price by the number of servings to compare real value.
- Other ingredients: some formulas pair CoQ10 with oils or extracts such as BioPerine® (black pepper extract), which is included in some products alongside fat-soluble nutrients.
How to Take CoQ10 or Ubiquinol | Timing Tips
CoQ10 in both forms is fat-soluble, so it's usually taken with a meal that contains some fat, such as eggs, avocado, fish or olive oil. Morning or evening both work; the best time is the one you'll stick with. Many people take it with breakfast alongside a multivitamin.
A few people ask whether ubiquinol can be taken at night. Yes, it can be taken with your evening meal if that suits your routine better.
Who Should Check With Their Doctor First?
Speak with your GP or pharmacist before taking any CoQ10 product if you:
- take blood-thinning medication such as warfarin
- take blood pressure or diabetes medication
- are pregnant or breastfeeding
- are having surgery or chemotherapy
Ubiquinol in Australia | Chemist vs Online
You'll find both forms at Australian pharmacies, including Chemist Warehouse, and online. Many budget "CoQ10" or "Q10" products are ubiquinone. If you specifically want ubiquinol, check that the word appears on the front of the pack and in the ingredient list, then compare cost per serve rather than bottle price.
