In a world where well-being and longevity are central concerns for many people, coenzyme Q10 is an essential nutrient. This natural compound, present in every cell of our body, plays a crucial role in energy production and protection against oxidative damage.
The basics of coenzyme Q10
Definition and origin of coenzyme Q10
Q10, also known as ubiquinone, is a powerful antioxidant produced naturally by the human body. It is found mainly in the mitochondria, the “energy power plants” of cells. The high presence of this coenzyme enables fats and sugars to be converted into energy that can be used by our bodies.
Role in cellular energy production
The main role of coenzyme Q10 is to facilitate the production of adenosine triphosphate (ATP), the fundamental unit of energy used by cells. It acts as an electron transporter in the mitochondrial respiratory chain, which is essential for ATP production. Without an adequate quantity of Q10, our cells would have difficulty producing enough energy to function properly.
Health benefits of coenzyme Q10
Antioxidant properties
As an antioxidant, Q10 neutralises free radicals, unstable molecules produced during normal cellular metabolism or by exposure to harmful external factors such as pollution. If left unchecked, these free radicals can cause cellular damage and accelerate the ageing process. Adding Q10 to your diet can help you better resist oxidative stress.
Cardiovascular support
Studies into the relationship between coenzyme Q10 and heart disease show that this nutrient can have significant beneficial effects on vascular health. By helping to improve myocardial function and reducing oxidative stress, Q10 can support the cardiovascular system. Research has also suggested its usefulness in the treatment of chronic heart failure.
- Improvement in the symptoms of heart failure
- Lower blood pressure
- Reduced bad cholesterol
Support for athletic performance
Athletes can benefit from coenzyme Q10 supplementation thanks to its properties in promoting cellular energy production. Increased levels of this coenzyme could help reduce muscle fatigue and improve recovery after intense training sessions.
Sources of coenzyme Q10
Food sources
Q10 is found in a variety of foods, mainly those rich in fat and protein. Here are a few examples:
- Red meat (beef, pork)
- Oily fish (mackerel, salmon, sardines)
- Nuts and seeds (peanuts, pistachios)
- Green vegetables (broccoli, spinach)
Coenzyme Q10 supplementation
For many people, obtaining coenzyme Q10 from food alone is not always enough, particularly in older people whose ability to produce this coenzyme diminishes with age. Supplements are available in various forms, including capsules, tablets and softgels. The latter are often preferred for their better absorption rates.
Coenzyme Q10 and ageing
Anti-ageing effects
Due to its powerful antioxidant properties, coenzyme Q10 plays a key role in combating the visible and internal signs of ageing. By protecting cells from damage caused by free radicals, this coenzyme helps to preserve skin elasticity, reduce wrinkles and maintain a youthful appearance.
Support for cognitive functions
Cognitive function often declines with age. Q10 can help protect the brain against oxidative stress, as well as improving the mitochondrial function of neurons, thereby promoting better cognition and memory.
Therapeutic applications of coenzyme Q10
Management of migraines
Studies show that coenzyme Q10 supplementation can be beneficial for people suffering from frequent migraines, probably by preventing mitochondrial dysfunction and reducing cerebral oxidative stress.
Skin care products
Many skincare products contain coenzyme Q10 for its ability to encourage cell regeneration and repair sun-induced damage. Applied topically, it promotes firmness, reduces fine lines and improves skin tone.
Factors influencing coenzyme Q10 levels
Ageing and deficiencies
Coenzyme Q10 levels tend to decrease with age. Specific conditions such as certain chronic diseases (e.g. diabetes, cancer) can also accelerate this natural decline. This is why supplementation is sometimes recommended for populations at risk.
Effects of certain drugs
Certain drugs, particularly statins used to treat high cholesterol, can limit the endogenous production of coenzyme Q10. This can lead to a reduction in body levels and require supplementation to compensate for these involuntary losses.
How to incorporate coenzyme Q10 into your daily routine
With meals
To optimise absorption of Q10, it is advisable to take it with meals containing fat. For example, a capsule taken with dinner accompanied by oily fish or a salad with olive oil could maximise results.
Choosing the right form of supplement
Softgels are often recommended because of their increased bioavailability. They allow faster and more effective absorption than other forms. It is crucial to choose quality products to guarantee the purity and effectiveness of the supplement.
