Coenzyme Q10 (also known as CoQ10 , ubiquinone or ubiquinol ) is a naturally occurring substance that plays a key role in energy production in the body's cells. It acts as an antioxidant that protects cells from free radical damage. CoQ10 is particularly well-known for its benefits related to heart health, energy production and cell protection. Whether to support the cardiovascular system or to promote youthful skin, CoQ10 is a versatile and popular supplement. In this article, you'll learn everything you need to know about Coenzyme Q10, its health benefits and how to get the most out of it.

What is coenzyme Q10?

Coenzyme Q10 is a fat-soluble antioxidant found in almost every cell in the body, especially in the mitochondria, the "powerhouses" of cells. It plays a central role in the production of adenosine triphosphate (ATP), the main energy source for cells. In addition to its function as an energy producer, CoQ10 protects cells from oxidative damage and supports the immune system [1]. There are two forms of coenzyme Q10: ubiquinone (the oxidized form) and ubiquinol (the active, reduced form).

In addition to coenzyme Q10, the molecule is also known by the names ubiquinone , ubiquinol , CoQ10 and Q10 . While ubiquinone is the common form found in supplements, ubiquinol is the more biologically active form that can be used directly in cells. Both forms provide health benefits, and supplements may contain either ubiquinone or ubiquinol [2].

Coenzyme Q10 occurs naturally in the human body, especially in organs with high energy requirements such as the heart, liver and kidneys. It can also be obtained in small amounts through food, particularly from meat, fish and plant sources such as spinach and broccoli. However, CoQ10 levels in the body decrease with age, so supplements are a good way to maintain CoQ10 levels and reap the health benefits [3].

Coenzyme Q10 can be produced in two main ways: either through a natural fermentation process that uses bacteria or yeast, or through a synthetic method from chemical compounds. The fermentation-derived form of CoQ10 is preferred because it more closely resembles the natural form found in the body. The finished CoQ10 extract is then used in dietary supplements such as capsules, tablets, or soft gel capsules [4].

Health Benefits of Coenzyme Q10

Coenzyme Q10 is particularly well-known for its positive effects on heart health. It supports the function of the heart muscle, improves energy production in cells, and acts as an antioxidant that protects the heart from oxidative damage. Studies have shown that CoQ10 can help lower blood pressure and relieve symptoms of heart failure [5]. People with cardiovascular disease, especially those with heart failure, may benefit from CoQ10 supplementation, as CoQ10 levels in the heart are often reduced in these conditions.

Because coenzyme Q10 plays a central role in energy production in cells, it is often used to increase energy levels and reduce fatigue. CoQ10 is especially important for the mitochondria, which are responsible for producing ATP. People with low CoQ10 levels, such as older adults or people with chronic diseases, may benefit from supplementation, as CoQ10 increases cellular energy and may improve physical performance [6].

Coenzyme Q10 is often used in anti-aging skin care products because it protects skin cells from oxidative stress and reduces the signs of aging, such as wrinkles and fine lines. It helps regenerate skin cells and supports collagen production, resulting in firmer and smoother skin. Through its antioxidant effects, CoQ10 can also help reduce UV damage and protect skin from premature aging [7].

Coenzyme Q10 is increasingly used to prevent migraines. Studies show that people with migraines often have lower CoQ10 levels, and taking CoQ10 may reduce the frequency and severity of migraine attacks. CoQ10 works by improving mitochondrial function and reducing oxidative stress, which reduces migraine attacks [8].

Athletes and active people often use CoQ10 to increase their physical performance. It improves energy production in muscles, reduces fatigue, and supports recovery after exercise. Studies suggest that CoQ10 can improve athletic endurance and reduce the production of lactic acid in muscles, increasing exercise intensity [9].

How does coenzyme Q10 work in the body?

Coenzyme Q10 plays a central role in the production of ATP in the mitochondria, which is crucial for cellular energy. It also acts as a powerful antioxidant that neutralizes free radicals and protects cells from oxidative damage. CoQ10 supports heart health by improving heart muscle function and increasing energy production. In addition, it promotes skin health and reduces inflammation in the body [10].

Recommended dosage and use of coenzyme Q10

The recommended dosage of coenzyme Q10 varies depending on the intended use, but is usually between 100 and 300 mg per day. For general health support and energy production, 100 to 200 mg daily is often recommended. For cardiovascular disease or migraines, higher doses of up to 300 mg per day may be useful. It is recommended to take CoQ10 with a meal because it is fat-soluble and is better absorbed when combined with fats [11].

Coenzyme Q10 can be taken at any time of day, preferably with a meal to improve absorption. Many people prefer to take it in the morning or midday to increase energy levels throughout the day. When used for migraine prevention or heart support, regular daily intake is important to achieve long-term results [12].

Side effects and safety of coenzyme Q10

Coenzyme Q10 is considered to be very safe and well tolerated. No serious side effects have been found in clinical studies, even at higher doses. However, people with certain pre-existing medical conditions or those taking blood-thinning medications should consult their doctor before taking CoQ10, as it can slightly affect blood clotting [13].

Rare side effects of coenzyme Q10 include mild gastrointestinal complaints such as nausea, diarrhea or upset stomach, especially at higher doses. In rare cases, headaches or dizziness may occur. It is recommended to reduce the dose or combine it with a meal to minimize side effects [14].

Coenzyme Q10 compared to other ingredients

Both coenzyme Q10 and L-carnitine are important for energy production in cells, but they work in different ways. While CoQ10 directly supports the ATP production process in the mitochondria, L-carnitine transports fatty acids into the mitochondria where they are burned for energy. Both can be used together to maximize energy production and physical performance [15].

Vitamin E and coenzyme Q10 are both powerful antioxidants, but they work in different parts of cells. Vitamin E protects cell membranes from oxidative damage, while CoQ10 is active in both cell membranes and mitochondria. Both can work synergistically and be used together to increase antioxidant protection in the body [16].

Natural Sources of Coenzyme Q10

Coenzyme Q10 is found in small amounts in foods, particularly in animal products such as meat, fish, and organ meats (especially heart and liver). Plant sources such as spinach, broccoli, and whole grains also contain CoQ10, but in much smaller amounts. Since the amounts in foods are relatively low, supplementation is often recommended to achieve therapeutic doses [17].

Final Thoughts on Coenzyme Q10

Coenzyme Q10 is a powerful antioxidant that offers numerous health benefits, including supporting heart health, promoting energy production, and protecting the skin from oxidative damage. Whether in capsule, soft gel, or gummy form, CoQ10 is a versatile and effective supplement to improve overall well-being. For people looking to support their heart function, increase physical performance, or care for their skin, Coenzyme Q10 is a valuable option.
