QUICK ANSWER
Muscle aches are the most common complaint on statins, but blinded trials show most of that pain is not caused by the drug. CoQ10 supplements are popular, yet the evidence is mixed and NICE does not recommend them for it. Before you blame the statin, it is worth checking whether it is actually working.
You started a statin to protect your heart. A few weeks in, your legs ache. It is the worry supplement forums keep circling back to: is my statin hurting my muscles, and should I take CoQ10?
The honest answer has two parts. Much of the aching people blame on statins is not the statin at all. And CoQ10, the go-to fix, has weaker evidence than the marketing suggests. Here is what the trials found, and the numbers that tell you more than the ache does.

As of July 2026. Reflects current NHS and British Heart Foundation guidance, NICE advice on CoQ10, and the 2020 SAMSON trial in the New England Journal of Medicine.
1. Are statins really causing your muscle aches?
Muscle aches are the side effect people report most. The NHS lists “muscle aches” as a common side effect of atorvastatin, the most-prescribed statin in the UK. So the worry is understandable.
Here is the twist. Aches and pains are common in everyone, statin or not. In blinded trials, where people do not know if they are taking the drug or a dummy pill, muscle symptoms often show up just as much on the dummy.
The clearest example is the 2020 SAMSON trial, run by Imperial College London and published in the New England Journal of Medicine. Sixty people who had quit their statins took turns on a statin, a placebo, and no pill. About 90% of the symptoms they blamed on the statin also appeared during the placebo months. This is the nocebo effect: real symptoms driven by the expectation of harm, not the drug.
That does not mean your ache is imaginary. It hurts. It just means the statin may not be the cause, and half the SAMSON group restarted successfully. A genuine excess of muscle pain from statins is real, but far smaller than the number of people who blame the drug.
One thing to take seriously: severe, widespread muscle pain or weakness with a high temperature and dark or brown pee is a rare but urgent sign. NHS advice is to call 111 straight away. For everyday aches, our guide to muscle cramps and blood tests covers the other common causes.
2. Does CoQ10 actually help?
CoQ10, or coenzyme Q10, is a compound your cells use to make energy. The theory is neat: statins can lower your CoQ10 level, so topping it back up should ease the aches. That is why ubiquinol, the active form of CoQ10, keeps trending in supplement threads.
The trouble is the trials do not agree. Some meta-analyses, which pool many studies together, found CoQ10 eased statin muscle symptoms. A widely cited 2019 analysis in the Journal of the American Heart Association reported a modest benefit. Other reviews found no difference from placebo. The studies were mostly small and short, at doses of 100 to 600 mg a day.
UK bodies have weighed this up and landed on caution. The British Heart Foundation is blunt about it:
“Current evidence does not support taking CoQ10 supplements for statin-attributed muscle pain.”
— British Heart Foundation
The BHF adds that NICE, which sets NHS treatment guidance, also advises against CoQ10 for this purpose. It is well tolerated and low-risk, so a personal trial is unlikely to harm you. But go in clear-eyed: you may be spending on a maybe. Our guide to which supplements are worth taking applies the same test to the rest of the shelf.
3. What should you check before blaming the statin?
An ache is a feeling. It cannot tell you whether your statin is doing its job. The more useful question is a number: is the drug actually lowering the risk it was prescribed for? Three markers answer that.
LDL AND APOB
LDL is the “bad” cholesterol a statin is meant to bring down. ApoB counts the harmful particles directly, and many cardiologists rate it the sharper measure of risk. If these are on target, your statin is working. See our guide to ApoB.
HS-CRP
High-sensitivity C-reactive protein measures low-grade inflammation, another driver of heart disease. A raised hs-CRP is worth knowing about in its own right. More in our guide to the hs-CRP blood test.
HBA1C
Statins can nudge blood sugar up slightly. HbA1c, your average blood sugar over about three months, gives useful context when you are on a long-term heart medication.
Our Advanced Heart Health panel (£159) measures all three, plus your full lipid profile and Lp(a), from a home finger-prick sample. For the plain-English version of those results, see our cholesterol blood test guide and the heart health hub. These tests measure your biomarkers and give you a wellness picture; they do not diagnose a condition, and anything that looks off should be discussed with a qualified clinician.
4. What should you do next?
The single most important rule: do not stop your statin on your own. It was prescribed to lower a real risk, and stopping it removes that protection. If the aches bother you, that is a conversation for your GP or pharmacist.
A clinician has options. A different statin, a lower dose, or dosing every other day all help some people. The BHF notes a change of dose or type often settles it, and a second go under guidance is often worth it.
If you want to try CoQ10 while you sort it out, it is low-risk. Take a baseline heart test first, keep taking your statin, and retest after a few months to see what changed. Measuring beats guessing.
Frequently asked questions
Do statins really cause muscle pain?
They can, but far less often than people assume. In the 2020 SAMSON trial, about 90% of the symptoms people blamed on their statin also appeared on a dummy pill. A genuine but small excess is real. If yours are troubling you, speak to your GP rather than stopping the drug.
Should I take CoQ10 with my statin?
The evidence is mixed. Some studies found CoQ10 eased statin muscle symptoms; others found no difference from placebo. The British Heart Foundation says current evidence does not support it, and NICE advises against it. It is low-risk, so a personal trial is unlikely to harm you, but it may not help either.
Do statins deplete CoQ10?
Statins can lower the body’s CoQ10 level, which is the theory behind supplements. But a lower level has not been reliably linked to the aches, and topping it up has not consistently fixed them in trials. The mechanism is plausible; the benefit is not proven.
When should statin muscle symptoms be treated as urgent?
Severe, widespread muscle pain or weakness alongside a high temperature and dark or brown pee is a rare but urgent sign. NHS advice is to call 111 straight away. This is very different from the everyday ache most people experience.
What blood test tells me if my statin is working?
A lipid panel with LDL cholesterol and ApoB shows whether the statin is lowering the particles it targets. Adding hs-CRP and HbA1c gives context on inflammation and blood sugar. Our Advanced Heart Health panel measures all of these from a home finger-prick sample.
