Coenzyme Q10 (CoQ10) is crucial for energy production and cellular health, particularly in high-energy organs and muscle tissue. It is also a powerful antioxidant.Β
Statins are used to lower cholesterol and reduce cardiovascular risk, but they can deplete CoQ10 levels, potentially causing muscle pain and weakness. Taking CoQ10 supplements alongside statins can help mitigate these side effects and enhance overall heart health, making it a beneficial addition for many patients on statin therapy.Β
The purpose of this article is to delve into the advantages and risks of taking CoQ10 and statins, their impact on cardiovascular disease risk, and the use of CoQ10 to help mitigate statin side effects and augment potential health benefits.Β

What Is CoQ10?
CoQ10 is a vitamin-like compound that is made in the body and exists in virtually all cell membranes. CoQ10 is particularly vital to mitochondrial production of ATP (the bodyβs energy source) and cellular respiration as part of the electron transport chain and, thus is an essential component of metabolic function (35). This makes it an especially important compound for organs with high energy demands, such as the heart and muscle tissues (49).Β Β
CoQ10, in its reduced form, ubiquinol, functions as a powerful antioxidant, scavenging free radicals that could otherwise damage tissues and lead to inflammation and disease processes. It can be recycled and reused and has a synergistic effect when in the presence of other antioxidants, such as Vitamins E and C (51).
Sources of CoQ10
The richest food sources of CoQ10 include:
- Organ meats such as liver and heart
- Beef, pork, chicken
- Fish such as herring, mackerel, sardines, and yellowtail
- Vegetable oils such as olive oil
- Nuts and seeds: peanuts, pistachios, sesame seeds, walnuts, hazelnuts
In supplement form, it can be commonly found as CoQ10, ubiquinone, or ubiquinol.Β
Benefits of CoQ10
- Improving heart health: many cardiovascular diseases, such as heart failure and atherosclerosis, are the result of oxidative stress. CoQ10βs antioxidant functions can help mitigate these effects and improve cardiovascular outcomes. Additionally, its role in energy production can improve heart muscle function, enhancing heart contractility (36).Β
- Fibromyalgia: fibromyalgia patients tend to have lower CoQ10 levels, suggesting CoQ10 deficiency as a potential cause (36). Patients supplementing with CoQ10 have demonstrated a significant reduction in symptoms.Β
- Blood pressure lowering effects: CoQ10 appears to lower blood pressure in hypertensive patients, likely through the production of nitric oxide, which helps to relax and dilate peripheral arteries (36).Β
- Blood sugar regulation: CoQ10 supplementation has been shown to reduce fasting insulin, fasting blood glucose, and hemoglobin A1c levels.
- Cancer benefit: CoQ10 helps to bolster immune system function and protect against oxidation, which are important strategies for managing and preventing cancer (36).Β Β
- Neurological antioxidant: CoQ10βs antioxidant actions may help to reduce oxidative processes that lead to and worsen neurodegenerative diseases such as Alzheimerβs and Parkinsonβs diseases (36).Β
What Are Statins?
Statin medications are an effective tool for managing cholesterol imbalances by lowering total cholesterol, low density lipoprotein (LDL), and triglyceride levels in patients with high cholesterol and reducing cardiovascular disease risk by up to 40% (48).Β
Statins work by inhibiting hydroxymethylglutaryl-CoA (HMG-CoA) reductase which is an enzyme involved in the production of cholesterol. This leads to reduced cholesterol synthesis in the liver and increased cholesterol uptake from the blood. In addition, statins exhibit anti-inflammatory, antioxidant, and plaque stabilizing effects (52).Β
Conditions Treated by Statins
- High cholesterol
- High triglycerides
- Atherosclerosis is a condition in which plaque builds up in the arteries
- Prevention of atherosclerosis-associated conditions such as heart attack, ischemic stroke, angina, and peripheral artery disease
- Nonalcoholic fatty liver disease
Common Statin Side Effects
Although generally well tolerated, statins can sometimes result in mild to severe side effects such as:
- Muscle pain and weakness
- Headache
- Nausea
- Diarrhea or constipation
- Liver dysfunction
- Increased risk for diabetesΒ
- Rhabdomyolysis in rare cases
Why Take CoQ10 and Statins Together?
Statins and CoQ10 Depletion
Although statins can effectively block cholesterol synthesis by inhibiting HMG-CoA reductase, they also have the unwanted effect of blocking CoQ10, which is produced along the same pathway (6). Indeed, statins have been found to reduce blood levels of CoQ10 in human studies.Β
The outcome of CoQ10 depletion is likely exacerbated by statin-induced effects on mitochondrial function, leading to poor muscle performance and muscle cell damage. This contributes to the muscle pain and cramping that some patients on statins experience, a main cause for treatment discontinuation (43). A study confirmed that symptomatic patients on statins showed evidence of structural muscle injury in their tissues.Β
Benefits of CoQ10 Supplementation with Statins
Muscle-related symptoms affect up to 25% of patients on statin therapy and are one of the main causes of statin dose reduction and discontinuation. This can have important health ramifications. One study found significant increases in all-cause mortality and cardiovascular disease incidence in patients who did not take statin therapy as prescribed.Β
CoQ10 supplementation offers a potential solution to help increase patient compliance by mitigating side effects. Recent randomized control studies demonstrated that supplementation with CoQ10 reduced statin-associated symptoms such as muscle pain, weakness, and cramping.Β
Additionally, CoQ10 use may offer additional cardiovascular benefits via its antioxidant actions and ability to improve heart function in those with cardiovascular comorbidities (36).Β
When CoQ10 and Statins Should Be Taken
In patients experiencing muscle symptoms while on statins or who could benefit from increased cardiovascular support, CoQ10 can be supplemented at a dose of 100-600 mg daily (48). The CoQ10/ubiquinone forms are preferable to ubiquinol for this purpose, as studies on ubiquinol could not produce the same cardiovascular benefit. Working with a healthcare provider is ideal to determine the most appropriate form, dosage, and timing for maximum effect.Β
Side Effects and Risks of CoQ10 and Statins
CoQ10 Supplementation Side Effects
As CoQ10 is produced naturally in the body, side effects of CoQ10 supplements are rare but can include:
- Upset stomach
- Nausea
- Diarrhea
- Mild insomnia
- Liver enzyme elevation at higher doses
Risks of Taking CoQ10 and Statins Together
Although CoQ10 is safe to take along with statin medications, it is important to work with a healthcare provider as both CoQ10 and statin can potentially interfere with other medicines.Β
Additionally, CoQ10 should not be taken in cases of gallbladder obstruction, and statins should be avoided in people with liver disease. Neither medication should be taken during pregnancy or when breastfeeding (53).
Lab Testing for Statins and CoQ10
CoQ10 Testing
CoQ10 testing can help identify which persons are at greatest risk for CoQ10 depletion and thus would benefit from supplementation.Β
Monitoring Cholesterol Levels
To monitor the efficacy of statin treatment, a fasting cholesterol panel should be measured before treatment and then every 4-12 weeks until the maintenance dose is achieved. After that, cholesterol should be monitored every 3-12 months to assess efficacy (52).Β
Moderate intensity statins should result in a 30-50% reduction in LDL, while high intensity doses can reduce LDL by 50% or more below baseline. In patients taking atorvastatin, full effects were achieved within 2 weeks of medication onset in 90% of individuals. If these levels are not met by the initial 4-12 week follow up, dosing or medication adjustments may be required (52).Β
Monitoring for Complications
- Liver function tests should be measured before initiating statin therapy as liver disease is a contraindication to statin use. Otherwise, liver function tests do not need to be routinely run unless liver symptoms develop.Β
- Creatine kinase testing, which assesses for muscle damage, is not needed unless severe muscle symptoms occur.Β
