Quick answer
- In the UK, NICE advises doctors not to recommend CoQ10 supplements for statin-related muscle symptoms.
- CoQ10 has no authorised health claim in the UK or EU; claims for energy, heart and statin side effects were not authorised.
- According to the US NIH, the evidence does not support CoQ10 for statin-related muscle pain, and it probably has no meaningful effect on blood pressure. Results for heart failure are inconclusive.
- No serious side effects have been reported, but CoQ10 may interact with warfarin.
- Ubiquinol costs more than ubiquinone; take either with a meal that contains fat.
Key numbers
- Authorised claims (UK and EU)
- None
- Typical supplement dose
- 100–200 mg/day
- Statin muscle pain (NIH summary)
- Evidence does not support use
- Known interaction
- Warfarin
What these terms mean: NRV upper levels (NHS, EFSA) maximum levels by country daily dose
How to choose
- Ask what you want it for: there is no proven benefit for statin muscle pain, energy or blood pressure in healthy people.
- If you take it, compare the mg of CoQ10 per daily dose and the cost per 100 mg.
- Ubiquinone is the standard, cheaper form; ubiquinol is the reduced form marketed as better absorbed, at a higher price.
- Choose softgels in oil or take capsules with a fatty meal; CoQ10 is fat-soluble.
- Avoid combinations with red yeast rice unless your GP agrees: they contain a statin-like substance. EU warning rules do not apply in Great Britain, so the label may not warn you.
CoQ10 products compared
| Type | What it is | Good to know |
|---|---|---|
| Ubiquinone capsules | The standard oxidised form | Cheapest per mg; take with food |
| Ubiquinone softgels in oil | CoQ10 dissolved in oil | Usually better absorbed than dry powder |
| Ubiquinol | The reduced form | Marketed as better absorbed; costs more |
| Combinations with red yeast rice | CoQ10 plus monacolins | EU limits and warnings apply in the EU and Northern Ireland, not in Great Britain; not with statins |
| “Energy” blends with B vitamins | CoQ10 plus vitamins | Any legal claim comes from the B vitamins |
What the evidence says
CoQ10 is part of how cells produce energy, and the body makes its own. Statins lower its level in the blood, which is why it is often suggested for statin muscle aches. According to the US National Center for Complementary and Integrative Health, results across studies vary but the overall evidence does not support that use; CoQ10 probably has no meaningful effect on blood pressure, and research in heart failure is inconclusive.
That leaves CoQ10 as a supplement with a good safety record and weak evidence of benefit. If you take medicines, check our guide to supplement labels and talk to your pharmacist.
What the label may legally claim
Authorised claims (GB and EU registers)
- None. EFSA assessed claims for energy, heart and blood pressure and they were not authorised.
Not authorised in GB or the EU

Who should be careful
- Warfarin: CoQ10 may interact with it; talk to your GP before starting or stopping.
- Cancer treatment: CoQ10 may not be compatible with some types of treatment; ask your oncology team.
- Red yeast rice combinations: in the EU and Northern Ireland, monacolins are capped below 3 mg a day with mandatory warnings, and a full EU ban passed its last vote in October 2026 (see our red yeast rice guide). Those rules do not apply in Great Britain. Not for use with cholesterol medicines.
FAQ
Should I take CoQ10 with statins?
Statins lower CoQ10 levels in the blood, but according to the US NIH the overall evidence does not support CoQ10 for statin-related muscle pain. Talk to your GP if you have muscle symptoms.
Is ubiquinol better than ubiquinone?
Ubiquinol is marketed as better absorbed, but both raise blood levels and ubiquinol costs more. Taking either with a fatty meal matters.
Is CoQ10 safe?
No serious side effects have been reported in studies. It may interact with warfarin and with some cancer treatments.
