What is CoQ10? Why does your body need it? Explained | FAQ

What is CoQ10?

Coenzyme Q10 (CoQ10) is a nutrient found in the human body. CoQ10 can also be found in a variety of foods. CoQ10 is an antioxidant that protects cells from harm while also playing a role in metabolism and aids in the production of energy in your cells.

Now what actually CoQ10 is lets dive deep !!

CoQ10 is a substance produced by your body and stored in your cells’ mitochondria

The mitochondria are in charge of energy production. They also protect cells from oxidative damage and bacteria or viruses that cause disease

As you become older, your body produces less CoQ10. As a result, it appears that older persons are deficient in this component.

CoQ10 deficiency can also be caused by the following factors:

  • Vitamin B6 deficiency is one example of a nutritional deficiency.
  • CoQ10 synthesis or utilization abnormalities are caused by genetic defects.
  • Tissue needs are increased as a result of illness.
  • Mitochondrial disorders are a group of diseases that affect the mitochondria of cells.
  • Age-related oxidative stress
  • Treatments with statins have side effects.

CoQ10 has been discovered to have a number of important roles in the human body.

One of its main jobs is to assist in the production of energy in your cells. It plays a role in the production of adenosine triphosphate (ATP), which is essential for energy transfer inside cells.
It also plays an important role as an antioxidant, protecting cells from oxidative damage.

Excessive levels of free radicals cause oxidative damage, which can impact negatively on normal cell activity. This is known to cause a variety of health problems.


Given that ATP is necessary to carry out all of the body’s functions and that oxidative damage is harmful to cells, it’s no surprise that low levels of CoQ10 have been related to chronic disorders.

Other cardiac diseases, such as coronary artery disease or excessive blood pressure, frequently lead to heart failure
Every cell in your body has CoQ10. The highest concentrations, on the other hand, are found in organs that require the most energy, such as the heart, kidneys, lungs, and liver.

Why do you need it?

CoQ10 is produced naturally by your body, however it tends to decrease as you get older. Fortunately, you can acquire CoQ10 through foods or supplements.

Low levels of CoQ10 have been associated to health problems such as heart disease, mental issues, diabetes, and cancer.

It’s unclear if low levels of CoQ10 cause or are a result of certain disorders.

One thing is certain: CoQ10 offers a long list of health benefits, as evidenced by numerous studies.

CoQ10’s 9 biggest benefits.

Supports Heart failure treatment

Other cardiac diseases, such as coronary artery disease or excessive blood pressure, frequently lead to heart failure.

Increased oxidative damage and inflammation of the veins and arteries can result from these situations.

Heart failure happens when these issues cause the heart to become unable to contract, relax, or pump blood through the body on a regular basis.

To make matters worse, some heart failure medicines have negative side effects like low blood pressure, while others may even lower CoQ10 levels.

Treatment with CoQ10 for two years alleviated symptoms and lowered the risk of dying from cardiac problems in 420 people with heart failure, according to a research.


Another trial gave CoQ10 or a placebo to 641 participants over the course of a year. Those who took CoQ10 were less likely to be hospitalized for worsening heart failure and had fewer significant consequences at the end of the research.


Treatment with CoQ10 appears to aid in the restoration of proper energy generation, the reduction of oxidative damage, and the improvement of heart function, all of which can help with the treatment of heart failure.

It aids to improve Fertility

Due to a decrease in the amount and quality of accessible eggs, female fertility diminishes with age.

CoQ10 plays a key role in this process. As you become older, your body’s production of CoQ10 diminishes, making it less effective at protecting your eggs from oxidative damage.
Supplementing with CoQ10 appears to help, and may even reverse, the quality and number of eggs as they mature.

Male sperm is also prone to oxidative damage, which can lead to a reduction in sperm count, poor sperm quality, and infertility.

CoQ10 supplementation has been shown in several studies to improve sperm quality, activity, and concentration by enhancing antioxidant protection.

It helps to Keep Your Skin Young

Your skin is your body’s greatest organ, and it’s constantly exposed to harmful substances that speed up the aging process.

Internal or external agents can be used. Cellular damage and hormone imbalances are two internal elements that might be harmful. Environmental agents, such as UV radiation, are examples of external variables.
Harmful substances can cause skin thinning, as well as a reduction in skin hydration and protection from environmental aggressors.

By enhancing energy synthesis in skin cells and promoting antioxidant defense, using CoQ10 directly to the skin can prevent damage from internal and external factors.

CoQ10 has been demonstrated to minimize oxidative damage caused by UV radiation and even lessen the depth of wrinkles when applied directly to the skin. Finally, those with low levels of CoQ10 appear to have a higher risk of developing skin cancer.

Helps to Reduce Headaches

Increased calcium uptake by cells, excessive generation of free radicals, and reduced antioxidant defense can all result from abnormal mitochondrial function.

Low energy in brain cells and even migraines might arise as a result of this. Increased calcium uptake by cells, excessive generation of free radicals, and reduced antioxidant defense can all result from abnormal mitochondrial function.

Low energy in brain cells and even migraines might arise as a result of this.

Because CoQ10 is found mostly in the mitochondria of cells, it has been demonstrated to increase mitochondrial activity and aid in the reduction of inflammation associated with migraines.

In fact, a research found that supplementation with CoQ10 reduced the occurrence of migraines in 42 participants three times more than a placebo.

In addition, persons who suffer from migraines have been found to have a CoQ10 deficiency. After therapy with CoQ10, 1,550 persons with low CoQ10 levels had fewer and less severe headaches, according to a larger study.

Furthermore, it appears that CoQ10 not only relieves but also prevents migraines.

Helps to boost Exercise performance

Muscle function, and consequently exercise performance, can be affected by oxidative stress.

Similarly, faulty mitochondrial function can lower muscular energy, making it difficult for muscles to contract properly and exercise for long periods of time.

CoQ10 improves mitochondrial activity and reduces oxidative stress in the cells, which can help with exercise performance.

In fact, one study looked into CoQ10’s impact on physical exercise. Oxidative stress was reduced in those who took 1,200 mg of CoQ10 per day for 60 days.


Furthermore, supplementing with CoQ10 can aid improve exercise performance by increasing power and decreasing weariness during exercise.

Diabetes assistance

Cell damage can be caused by oxidative stress. Diabetes and other metabolic illnesses can arise as a result of this.

Insulin resistance has also been linked to abnormal mitochondrial activity.

CoQ10 has been shown to help manage blood sugar levels and increase insulin sensitivity.

Supplementing with CoQ10 may help enhance CoQ10 levels in the blood by up to three times in diabetics who normally have low amounts of this component.

In another trial, patients with type 2 diabetes were given CoQ10 supplements for 12 weeks. Fasting blood sugar levels and hemoglobin A1C, which is the average of blood sugar levels over the previous two to three months, were both dramatically reduced.

Finally, CoQ10 may aid in the prevention of diabetes by increasing fat breakdown and lowering fat cell accumulation, both of which can lead to obesity and type 2 diabetes.

Helps in Cancer Prevention

Cell damage and function are known to be affected by oxidative stress.

The structure of your cells can be harmed if your body is unable to adequately battle oxidative damage, thus raising the risk of cancer.

CoQ10 has been shown to protect cells from oxidative stress and boost cellular energy production, thereby enhancing their health and survival.
It’s worth noting that cancer patients have reduced amounts of CoQ10.

Low levels of CoQ10 have been linked to a 53.3 percent increased risk of cancer, as well as a poor prognosis for many cancers.

Furthermore, one study found that taking CoQ10 supplements may help minimize the risk of cancer recurrence.

Good for Brain Health

Mitochondria are the brain’s principal energy providers.

Mitochondrial function deteriorates as people get older. Total mitochondrial malfunction can result in brain cell death and disorders such as Alzheimer’s and Parkinson’s.

Unfortunately, due to its high fatty acid content and high oxygen demand, the brain is extremely vulnerable to oxidative injury.

This oxidative damage increases the formation of toxic chemicals, which may have an impact on memory, cognition, and physical functions.

CoQ10 may lower these toxic chemicals, perhaps reducing Alzheimer’s and Parkinson’s disease progression.

Protects the Lungs

The lungs have the greatest oxygen contact out of all of your organs. As a result, they are extremely vulnerable to oxidative stress.

Lung illnesses including asthma and chronic obstructive pulmonary disease can be caused by increased oxidative damage and a lack of antioxidant defense, which includes low levels of CoQ10 (COPD).

Furthermore, patients with these illnesses have been observed to have reduced CoQ10 levels.

A study found that taking CoQ10 supplements lowered inflammation in people with asthma, as well as their need for steroid drugs to manage it.

Another study found that those with COPD improved their exercise performance. After supplementing with CoQ10, improved tissue oxygenation and heart rate were seen.

Frequently asked questions (FAQ)

What are the symptoms of CoQ10 deficiency?

While everyone is different, people with low CoQ10 levels frequently experience physical tiredness and muscle weakness, even when doing relatively non-strengthening activities like walking.

Is CoQ10 bad for the liver?

CoQ10 supplements and a balanced diet can help the liver repair and reverse the symptoms of alcoholic liver disease. The University of Alabama in Birmingham carried out this ground-breaking study (UAB).

What are the side effects of CoQ10 ?

While most individuals tolerate coenzyme Q10 well, it might induce stomach irritation, lack of appetite, nausea, vomiting, and diarrhea in some people. Some people may experience allergic skin rashes as a result of it. It may also drop blood pressure, so if you have extremely low blood pressure, keep an eye on it.

What are the Natural sources of CoQ10?

CoQ10 is easily obtained as a supplement, but it can also be present in some foods.

CoQ10 appears to be absorbed similarly in pill form or through meals.

CoQ10 is found in the following foods:

  • Organ meats: Heart, liver and kidney
  • Some muscle meats: Pork, beef and chicken
  • Fatty fish: Trout, herring, mackerel and sardine
  • Vegetables: Spinach, cauliflower and broccoli
  • Fruit: Oranges and strawberries
  • Legumes: Soybeans, lentils and peanuts
  • Nuts and seeds: Sesame seeds and pistachios
  • Oils: Soybean and canola oil

What is the dosage of CoQ10 per day ?

The recommended daily intake of CoQ10 is between 90 and 200 milligrams. Levels as high as 500 mg appear to be well tolerated, and several studies have employed even higher doses with no significant side effects.

Because CoQ10 is a fat-soluble molecule, it has a sluggish and limited absorption rate. Taking CoQ10 pills with food, on the other hand, can help your body absorb it up to three times faster than taking it alone.

Does CoQ10 lower cholesterol?

Supplementing with CoQ10 may also help to decrease cholesterol and improve heart health naturally. While there aren’t enough trials to prove how effective this is, it’s feasible that combining CoQ10 with statins can improve results.

Can taking CoQ10 be harmful?

While most individuals tolerate coenzyme Q10 well, it might induce stomach irritation, lack of appetite, nausea, vomiting, and diarrhea in some people. Some people may experience allergic skin rashes as a result of it. It may also drop blood pressure, so if you have extremely low blood pressure, keep an eye on it. You should stop taking CoQ10 immediately once you notice such a extreme symptom and contact your doctor.

Does CoQ10 help sexually?

The results of the study revealed that CoQ10 medication improved plaque size, penile curvature, poor sexual function, and erection pain.

Can CoQ10 increase testosterone?

Coenzyme Q10 supplementation has so far had no discernible influence on testosterone levels in human males, according to research. Similarly, animal experiments did not reveal that coenzyme Q10 has a favorable effect on testosterone, unlike the reproductive toxicity studies.

Should I take CoQ10 before bed?

It’s important to note that taking CoQ10 right before bedtime may cause insomnia in some people, so it’s best to take it in the morning or afternoon. Some popular medications, such as blood thinners, antidepressants, and chemotherapy therapies, may interact with CoQ10 supplements.

Does CoQ10 increase blood flow?

Following that, researchers examined how well blood flowed through the arteries of the participants in the study. The outcomes were positive. The CoQ10 supplement enhanced blood vessel health by 42 percent, implying a 13 percent reduction in the risk of heart disease, according to the study.
