Coenzyme Q10, also known as coenzyme Q10 or simply CoQ10, is a natural compound found in every cell in the body. This important element plays two main roles: it helps produce energy in the mitochondria (the “power plants” of cells) and it acts as a powerful antioxidant, protecting cells from damage caused by free radicals.
The highest concentrations of coenzyme Q10 are found in the cells of organs that require the most energy, such as the heart, liver, and kidneys. In addition to its antioxidant effects, coenzyme Q10 is particularly valued for supporting natural energy production, a property it shares with other recognized vitamin supplements for energy.
In this in-depth article, you will learn about coenzyme Q10 and its importance to health, the research-backed benefits for various body systems, appropriate dosages, food sources, safety aspects, and potential drug interactions. You will also compare this coenzyme Q10 supplement to other popular supplements.
What is coenzyme Q10 and how does it work?
Coenzyme Q10, scientifically known as ubiquinone, is a vitamin-like substance that is naturally produced by our bodies. The name of this compound comes from the words “ubiquinone” – “ubiquitous” (present everywhere) and “quinone” (specific chemical structure). The name reflects the fact that this compound is found in virtually all living cells.
Coenzyme Q10 functions as a cofactor – a helper molecule that is involved in numerous biochemical reactions. Its role is particularly important in mitochondria, where it participates in the electron transport chain – a complex process that converts nutrients into ATP (adenosine triphosphate), the universal energy carrier in the body.
This compound exists in two forms: an oxidized form (ubiquinone) and a reduced form (ubiquinol). Ubiquinol is an active antioxidant form that neutralizes free radicals and protects cell membranes and DNA from oxidative stress. It is important to note that the body’s natural production of coenzyme Q10 decreases with age, so older people may benefit from supplementing with this substance.
Although coenzyme Q10 is a natural substance in the body, certain factors can reduce its levels. For example, cholesterol-lowering drugs of the statin class can block the synthesis of not only cholesterol but also coenzyme Q10, since both use the same biochemical pathway. Also, chronic diseases, intense physical activity and the aging process can reduce the concentration of this important compound in the body.

Dosage, Supplements, and Natural Food Sources
To get the most out of your CoQ10, it’s important to know the right dosage, optimal supplement forms, and natural food sources. This section will discuss these important aspects.
How much CoQ10 should you take?
CoQ10 dosage can vary depending on individual needs, age, and health status. Standard doses range from 30 to 200 mg per day, although higher doses of up to 1,200 mg per day may be recommended for some health conditions.
A dose of 100-200 mg per day is generally recommended for the prevention of cardiovascular disease. People taking statins may benefit from taking 100-200 mg per day to compensate for the decrease in CoQ10 levels caused by these medications.
Doses of 100-300 mg per day have been used in studies for migraine prevention. For energy and general health, 30-100 mg per day is usually sufficient.
It is important to note that coenzyme Q10 is a fat-soluble compound, so its absorption is improved when taken with food, especially one containing fat. Additionally, splitting the daily dose into smaller portions (for example, taking it twice a day instead of one larger dose) may improve bioavailability.
It is always recommended to consult a doctor before starting any new supplement, especially if you have a chronic condition or are taking medication. Some people, such as those taking blood thinners, may require special monitoring.
Coenzyme Q10 in foods
While coenzyme Q10 is naturally produced in the body, it can also be obtained from some foods. However, food sources generally provide relatively small amounts of coenzyme Q10 compared to supplements.
The highest concentrations of coenzyme Q10 are found in:
- animal by-products, especially heart, liver and kidney
- oily fish such as salmon, mackerel and sardines
- meat, especially beef
- oils, especially soybean and canola oils
- nuts, especially pistachios and peanuts
- certain vegetables, especially broccoli, cauliflower and spinach
It should be noted that heat treatment can destroy some of the coenzyme Q10 in food, so raw or minimally cooked foods may be a better source of this compound.
It is important to understand that even when eating foods rich in coenzyme Q10, the amount obtained is usually much less than the recommended therapeutic dose. For example, 100 grams of beef heart provides about 11 mg of coenzyme Q10, which is less than a typical supplement dose.
Vegan and high bioavailability options
Many traditional CoQ10 supplements are derived from animal sources or through fermentation. However, vegan alternatives are also available.
Vegan CoQ10 supplements are usually made from fermented yeast. It’s important for vegans to pay attention to the capsule ingredients before purchasing any supplement—many capsules are made from gelatin, which is an animal product. Look for products labeled “vegan” or “vegan-friendly,” or those that use plant-based capsules, such as cellulose or carrageenan capsules.
When it comes to bioavailability, there are two main forms of CoQ10 in supplements: ubiquinone (the oxidized form) and ubiquinone (the reduced form). Ubiquinol is the more active form and some studies suggest that it may have better bioavailability than the ubiquinone form. However, ubiquinol is generally more expensive.
Bioavailability can also be improved by using advanced delivery systems such as liposomal formulations or micronized formulations. These formulations are designed to improve the absorption and utilization of CoQ10 in the body.
Finally, when choosing a CoQ10 supplement, pay attention to the overall quality of the product. Look for products that have been tested by third parties such as USP or NSF and are manufactured according to GMP (Good Manufacturing Practice) standards. This will help ensure that you are getting a high-quality product free from impurities.
Safety, Side Effects, and Drug Interactions
Coenzyme Q10 is generally considered safe for most people when taken at recommended doses. However, like any supplement, it can cause side effects and interact with certain medications, so it’s important to be aware of the potential risks.
Who should be careful?
Although coenzyme Q10 is a natural compound and is generally well-tolerated, some people should be cautious when taking its supplements:
- People taking blood thinners: Coenzyme Q10 may have a mild blood-thinning effect, so people taking warfarin or other anticoagulants should consult their doctor before taking this supplement.
- People taking medications for hypertension: Since coenzyme Q10 may lower blood pressure, people already taking medications for hypertension should monitor their blood pressure and consult their doctor.
- People undergoing cancer treatment: Some studies suggest that coenzyme Q10 may interact with some chemotherapy drugs, so people with cancer should consult their oncologist before taking this supplement.
- Pregnant or nursing women: While there is no specific evidence that coenzyme Q10 is harmful during pregnancy, there is a lack of comprehensive studies in this group, so it is recommended to consult a doctor.
- People preparing for surgery: Due to its potential blood-thinning effects, coenzyme Q10 should be discontinued at least two weeks before a scheduled surgery.
Finally, while coenzyme Q10 may be beneficial for people taking statins to lower cholesterol (as statins can reduce the body’s natural levels of coenzyme Q10), it is important to begin such supplementation under the supervision of a doctor to avoid potential interactions.
Millions of people take coenzyme Q10 safely, but it’s wise to consider not only potential drug interactions but also the broader context of maintaining a healthy immune system—especially if you’re taking multiple supplements.
Coenzyme Q10 vs. Other Popular Supplements
There are a number of supplements on the market that offer antioxidant protection and energy-boosting properties. Let’s compare the unique properties of coenzyme Q10 to other popular supplements.
Coenzyme Q10 vs. Vitamin E: Both of these compounds are powerful antioxidants, but they work in different parts of the cell. Vitamin E works primarily in cell membranes, while coenzyme Q10 works in the mitochondria. Also, unlike vitamin E, coenzyme Q10 is directly involved in the energy production process. These two antioxidants can work synergistically, so their combination may be more beneficial than either one alone.
Coenzyme Q10 vs. Astaxanthin: Both of these compounds are potent antioxidants. Astaxanthin, a member of the carotenoid family, is the pigment that gives salmon and shrimp their pink color. While astaxanthin may be a more powerful antioxidant than coenzyme Q10, it does not play a direct role in energy production. Some studies suggest that the combination of astaxanthin and coenzyme Q10 may provide additional benefits for heart health.
Coenzyme Q10 vs. alpha-lipoic acid (ALA): ALA is another powerful antioxidant that, like coenzyme Q10, is naturally produced in the body. However, ALA is soluble in both water and fat, allowing it to function in different parts of the cell. Both compounds are involved in energy production, but they perform different functions. Coenzyme Q10 is an electron carrier in the electron transport chain, while ALA is a cofactor for several enzymes involved in energy metabolism.
Coenzyme Q10 vs. resveratrol: Resveratrol is a polyphenol found in red wine and berries that is known for its potential benefits for heart health. While both compounds have antioxidant properties, resveratrol may also have anti-inflammatory effects and potentially activate longevity genes. However, unlike coenzyme Q10, resveratrol is not directly involved in energy production.
Coenzyme Q10 vs. B vitamins: B vitamins, especially B1 (thiamine), B2 (riboflavin), and B3 (niacin), are important for energy production. However, unlike coenzyme Q10, they do not have an antioxidant function. Additionally, coenzyme Q10 levels naturally decline with age, and B vitamin levels can usually be maintained through a balanced diet.
Individuals who are active athletes may also want to consider sports nutrition options designed to enhance endurance in conjunction with coenzyme Q10.
Ultimately, it is important to consider individual health goals and needs when choosing a supplement. While coenzyme Q10 may be beneficial for many people, it is not a one-size-fits-all solution. Some people may benefit from combining coenzyme Q10 with other supplements, but it is always recommended to consult a healthcare professional before starting any supplement regimen.
