Coenzyme Q10 for Relieving Asthma Symptoms?

Coenzyme Q10 for Relieving Asthma Symptoms?

The results of a recent study suggest that supplementation with coenzyme Q10 may be beneficial to asthma patients.  Specifically, these results suggest that Coenzyme Q10 may reduce the long-term use of corticosteroids in asthma patients. Coenzyme Q10 is also a supplement of potential interest for those who suffer from migraine headaches.

Asthma, a common chronic respiratory condition, affects millions of people worldwide. It’s characterized by inflammation and narrowing of the airways, leading to a range of symptoms that can vary in severity and frequency. Understanding these symptoms is crucial for effective asthma management and ensuring a better quality of life for those affected. Let’s explore the key symptoms of asthma and their impact.

Common Symptoms of Asthma

Asthma symptoms can differ from person to person, but there are several common signs to look out for:

  1. Wheezing: A high-pitched whistling sound when breathing, particularly when exhaling, is one of the most recognizable symptoms of asthma. It’s caused by the narrowing of airways and the passage of air through constricted spaces.
  2. Coughing: Frequent coughing, especially at night or early in the morning, can be a sign of asthma. The cough is often dry and can be severe enough to interfere with sleep.
  3. Shortness of Breath: People with asthma may feel like they can’t catch their breath or get enough air into their lungs. This feeling can occur either at rest or during physical activity.
  4. Chest Tightness or Pain: A feeling of pressure or discomfort in the chest is a common asthma symptom, often described as a band tightening around the chest.
  5. Difficulty Sleeping: Respiratory symptoms like coughing and wheezing can make it hard to sleep through the night.

In the world of health and wellness, certain nutrients gain celebrity status, and one such nutrient that has been attracting attention is Coenzyme Q10 (CoQ10). This vital compound, found naturally in our bodies and in certain foods, plays a crucial role in our overall health. Let’s delve into what CoQ10 is, its benefits, sources, and why it’s important.

What is Coenzyme Q10?

Coenzyme Q10, also known as ubiquinone or ubiquinol, is a fat-soluble substance that resembles a vitamin. It’s found in every cell of the human body and is essential for the production of energy. CoQ10 is particularly concentrated in the organs with the highest energy demands, such as the heart, kidneys, liver, and muscles.

The Role of CoQ10 in the Body

The primary function of CoQ10 is in cellular energy production. It’s a key component in the mitochondria, the powerhouse of the cell, where it helps convert food into energy. CoQ10 also acts as an antioxidant, protecting cells from damage caused by harmful molecules known as free radicals.

Health Benefits of CoQ10

  1. Heart Health: CoQ10 has been shown to benefit heart health in several ways. It helps maintain the normal oxidative state of LDL cholesterol, helps assure circulatory health, and supports optimal functioning of the heart muscle.
  2. Energy Boost: Since CoQ10 aids in energy production, it can help increase energy levels, making it popular among people suffering from fatigue-related conditions.
  3. Antioxidant Protection: CoQ10’s antioxidant properties help protect cells from oxidative damage, a key factor in aging and many chronic diseases.
  4. Supports Neurological Health: Research suggests that CoQ10 might have protective effects against neurological disorders, as these conditions are often linked to mitochondrial dysfunction.

Sources of CoQ10

While the body can produce CoQ10 naturally, its production tends to decrease with age. Fortunately, CoQ10 can also be obtained from the diet. Foods rich in CoQ10 include:

  • Fatty fish like salmon and tuna
  • Organ meats such as liver
  • Whole grains
  • Spinach, cauliflower, and broccoli

CoQ10 Supplements

For those who don’t get enough CoQ10 from their diet, or for individuals with certain health conditions, supplements can be beneficial. CoQ10 supplements are available in various forms, including capsules, tablets, and liquids. It’s important to note that the absorption of CoQ10 can be slow and limited, so taking it with a meal containing fats can improve its absorption.

Safety and Side Effects

CoQ10 is generally well-tolerated, and side effects are rare. However, it’s always advisable to consult with a healthcare provider before starting any new supplement, especially for those on medication or with existing health conditions.


“Bronchial asthma is a chronic inflammatory disease of respiratory system, with disturbances in the dynamic balance of oxidant-antioxidant capacity of the lungs. Long-term administration of corticosteroids has been shown to result in mitochondrial dysfunction and oxidative damage of mitochondrial and nuclear DNAs.”

Study Intervention:

  • CoQ(10) as Q-Gel (120 mg) + 400 mg alpha-tocopherol + 250 mg vitamin C per day

Study Conclusions:

“Data show that patients with corticosteroid-dependent bronchial asthma have low plasma CoQ(10) concentrations that may contribute to their antioxidant imbalance and oxidative stress. A reduction in the dosage of corticosteroids required by the patients following antioxidant supplementation was observed, indicating lower incidence of potential adverse effects of the drugs, decreased oxidative stress. “

Conclusion:  Supplementation with Coenzyme Q10 could be beneficial for patients who take corticosteroid medication to control their asthma symptoms.
