What Is CoQ10? 8 Advantages for Aging, Brain and Heart Health

What Is CoQ10? 8 Benefits for Energy, Aging, and Brain and Heart Health

The enzyme coenzyme Q10 (COQ10) is necessary for numerous daily processes. In actuality, every cell in the body needs it.CoQ10 is an antioxidant that shields cells from the effects of aging and has long been utilized in medicine, particularly to address cardiac issues.Even while we produce some coenzyme Q10 on our own, there are still benefits to ingesting more of it, and a deficiency in CoQ10 is linked to the harmful consequences of oxidative stress. It is believed that a lack of CoQ10 is related to diseases like diabetes, cancer, fibromyalgia, heart disease, and cognitive loss.Is CoQ10 right for you? Let’s find out.

What Is CoQ10?

Coenzyme Q10 is a vital component that acts as an antioxidant in the body despite the name, which may not sound particularly natural. It is known as ubiquinone or ubiquinol when it is active.

The entire body contains coenzyme Q10, with the largest concentrations found in the heart, liver, kidneys, and pancreas. It plays a role in energy generation since it is stored in your cells’ mitochondria, which are frequently referred to as the “powerhouse” of the cell.

What uses does CoQ10 have? It performs crucial tasks such moving electrons, delivering energy to cells, and controlling blood pressure.

CoQ10 is a “coenzyme” that aids in the normal functioning of other enzymes. Due to the fact that all animals, including humans, can make small amounts of coenzymes on their own, even without the help of food.heart disease and cognitive decline.

While humans make some CoQ10, CoQ10 supplements are also available in various forms — including capsules, tablets and by IV. CoQ10 for Male Fertility | Forever Cardiohealth Contains CoQ10

How CoQ10 Works:

  • To sustain enough energy to perform bodily functions, inside our cells tiny organelles called mitochondria take fat and other nutrients and turn them into useable sources of energy. This conversion process requires the presence of CoQ10.
  • Coenzyme Q10 is not only necessary for producing cellular energy, but also for defending cells from damage caused by harmful free radicals.
  • Coenzyme Q10 can exist in three different oxidation states, and the ability in some forms to accept and donate electrons is a critical feature in its biochemical functions that cancel out free radical damage.
  • As a powerful antioxidant, Coenzyme Q10 can increase absorption of other essential nutrients. It’s been shown that it helps recycle vitamin C and vitamin E, further maximizing their effects.

Should I Take a CoQ10 Supplement?

Who ought to take CoQ10? Beyond the age of about 40, when we most rely on our cells for protection, we naturally create less CoQ10. This implies that older people and those who desire to age gracefully may choose to supplement with it.

According to study, CoQ10 appears to be created in sufficient amounts in healthy people through natural synthesis and diet. However, when we age and develop certain illnesses, like heart disease, our capacity to produce CoQ10 decreases.

CoQ10 Deficiency:

Some contributing factors to CoQ10 deficiency/low levels, besides aging and genetic defects, are believed to include:

  • Having chronic diseases, such as diabetes, cancer and congestive heart failure
  • High levels of oxidative stress
  • Nutritional deficiencies in B vitamins
  • Mitochondrial diseases
  • Taking statin drugs

Rarely, a person may suffer from “primary coenzyme Q10 deficiency,” which is a genetic defect that stops the body from properly synthesizing this compound. For these individuals, supplementing with CoQ10 is typically needed to help reverse brain- and muscle-related symptoms.

COQ10 Benefits

1. Sustains Natural Energy

CoQ10 contributes to “mitochondrial ATP synthesis,” which is the process by which food energy (carbohydrates and fats) are transformed into adenosine triphosphate, the type of energy that is used by our cells (ATP).

Coenzyme Q must be present in the inner mitochondrial membrane for this conversion step. Its function in the metabolism of fatty acids and glucose includes taking in electrons and transferring them to electron acceptors.

Every cell in the human body depends on the production of ATP, which also enables communication between cells. ATP production is essential for maintaining energy (at the cellular level), and it depends on CoQ10 to function.

CoQ10 may even reduce fatigue related to exercise. Three separate double-blind, placebo-controlled studies in humans have shown improvements in exercise-related fatigue when supplemented with CoQ10 (at dosages between 100–300 milligrams per day).

2. Reduces Free Radical Damage

When the body’s low-density lipoproteins and cell membranes are exposed to oxidative conditions from the outside, lipid peroxidation takes place. CoQ10 is a water- and fat-soluble antioxidant that has been demonstrated to prevent this from happening.

CoQ10 is really one of the earliest antioxidants used to help mitigate the effects of LDL oxidation.

Coenzyme Q10 has been shown to protect DNA and membrane proteins from oxidative damage brought on by lipid peroxidation in mitochondria and to directly neutralize free radicals, which are the root cause of practically all age-related diseases (heart disease, cancer, diabetes, neurological disease, etc.).

One way this might be especially helpful is suggested by a study showing that CoQ10 may help protect against some oxidative stress caused by insulin resistance and associated to diabetes.

3. Can Improve Heart Health and Offset Effects of Statin Drugs

CoQ10 has a significant promise for both the prevention and treatment of cardiac conditions, despite the opinion of experts that more rigorous clinical trials are still required to demonstrate its effects. It achieves this via enhancing free radical scavenging capacities, functioning as an antioxidant, and enhancing cellular bioenergetics.

What is known is that statin users and those with elevated cholesterol may benefit from taking CoQ10 supplements. That is as a result of its effects on decreasing cholesterol.

In some groups, particularly diabetics, coenzyme Q10 may help lower levels of total and low-density lipoprotein (LDL) cholesterol.
Additionally, it might lessen the possibility of statin-related adverse effects like weariness. Statins are used to diminish a liver enzyme that not only lowers cholesterol production but also also further lowers the natural production of CoQ10.

CoQ10 may interact with lipid-lowering drugs that stop the function of HMG-CoA reductase, an essential enzyme in the production of both cholesterol and coenzyme Q10. It is frequently advised to take a CoQ10 supplement to boost natural levels back to optimal levels and combat statin side effects, such as muscle soreness.

As several reviews have discovered, there is insufficient data to formally advocate CoQ10 supplementation for people taking statins, some research is contradictory.

CoQ10 can also assist the heart and circulatory system in other ways besides this, though.

Does CoQ10 increase blood flow? Yes, and for those who have had heart failure, it may be able to improve exercise performance and capacity by increasing blood flow.

Does coenzyme Q10 reduce blood pressure? Overall, study findings have been conflicting.

According to the National Institutes of Health, “The small amount of evidence currently available suggests that CoQ10 probably doesn’t have a meaningful effect on blood pressure.”

However, a 2002 review published in the Journal of Cardiovascular Nursing states:

[CoQ10] has potential for use in prevention and treatment of cardiovascular disease, particularly hypertension (high blood pressure), hyperlipidemia, coronary artery disease, and heart failure…  Further clinical trials are warranted, but because of its low toxicity it may be appropriate to recommend coenzyme Q10 to select patients as an adjunct to conventional treatment.

4. Slows Down Effects of Aging (Including Skin Changes)

Mitochondrial ATP synthesis is an important function for maintaining a fast metabolism, strength of muscles, strong bones, youthful skin and healthy tissue, and abnormal mitochondrial can cause issues.

Although supplementing with CoQ10 has not been shown to increase the life span of animals that have been tested with it, researchers believe it can slow down the age-related increase in DNA damage that naturally affects us all. Possible anti-aging benefits of consuming more CoQ10 include:

  • Protection of the heart against stress-related aging.
  • Protection of skeletal muscle genetic structure to keep those muscles strong, minimizing bone and joint injury risk.
  • Improved fertility during your 40s by the reversal of egg degradation and increased production of ATP.
  • Increased activity of antioxidants catalase and glutathione to protect cell membranes throughout the body from free radical damage.
  • Reduced UV skin damage and signs of skin aging, such as wrinkles and loss of elasticity (when applied as topical cream and/or taken as a supplement). One randomized, placebo-controlled, double-blind study found that 150 mg/day of CoQ10 limited deterioration of viscoelasticity, improved smoothness and reduced some visible signs of aging when taken for 12 weeks.

5. May Help Protect Against Cancer

Within cells, CoQ10 helps transport proteins across membranes and separate certain digestive enzymes from the rest of the cell, which helps maintain optimal pH. It’s believed that diseases develop more easily in environments that have to work harder to maintain proper pH levels.

This, in addition to its major antioxidant capacity, may be one reason that cancer risk may be reduced among people with higher CoQ10 levels. Here are other reasons:

  • Increasing impact of chemotherapy drugs and protect from side effects: Supplementing with CoQ10 during cancer treatment may help increase the cancer-killing potential of these medications (like doxorubicin and daunorubicin). There is also evidence that CoQ10 can protect the heart from DNA damage that can sometimes occur from high doses of chemotherapy medications.
  • May slow or reverse spread of breast cancer: According to a 2017 article in Future Oncology, “Medical methods are available for the treatment of BC… Coenzyme Q10, an antioxidant that can target the pathways behind BC tumor development, is a promising contender. Not only that. A 1994 study monitored 32 breast cancer patients (aged 32 to 81) who were deemed “high-risk” because of how their tumors had migrated to their lymph nodes. Nutritional antioxidants, vital fatty acids, and 90 milligrams of CoQ10 were administered to each patient on a daily basis. Not only were there no patient deaths over the 18-month research period, but there were also no patient worsenings, improvements in all patients’ quality of life, and six patients who entered partial remission. Two of the patients in partial remission were then given more coenzyme Q10 (300 milligrams each day), both of whom went into totally remission, showing complete absences of previous tumors and tumor tissue (one after two months, the other after three months).
  • Could help prevent colon cancer: One research study discovered CoQ10 significantly lowered oxidative stress in the colon that leads to colon cancer.
  • Might play a role in the prevention of cervical cancer: Low levels of CoQ10 are seen in patients with cervical cancer, although it’s not clear why.
  • May improve survival rate in end-stage cancers: 41 individuals were tracked in a pilot research for nine years with varied primary malignancies that had progressed to stage four and were given CoQ10 supplements along with an extra antioxidant combination. In the patients who were monitored, the median survival duration was 17 months, which was five months longer than anticipated overall. With minimal to no negative effects from the medication, 76 percent of the patients overall survived longer than was typical.

6. May Protect Cognitive Health

In those with cognitive impairments, such as Parkinson’s disease, increased oxidative stress in a part of the brain called the substantia nigra is thought to contribute to symptoms.

CoQ10 has been shown to offset decreases in activity of mitochondrial electron transport chains that affect nerve channels and brain function, and studies show that people with cognitive disorders tend to have reduced levels of CoQ10 in their blood.

One randomized, placebo-controlled trial that evaluated the efficacy of 300, 600 or 1,200 milligrams a day given to 80 people with early Parkinson’s disease found that supplementation was well-tolerated and associated with slower deterioration of cognitive functions compared to the placebo. That being said, not every study has found coenzyme Q10 to be effective over placebo.

Some preliminary studies have found positive outcomes in lab and research studies, and a few small human clinical trials, for CoQ10 to treat cognitive decline seen in other neurological diseases, including progressive supranuclear palsy, Huntington’s disease, amytrophic lateral sclerosis and Friedreich’s ataxia.

Regarding the most well-known neurodegenerative disease, Alzheimer’s disease, there have been little to no human trials conducted using CoQ10. However, research studies have found modestly positive results, making coenzyme Q10 a possible addition to an Alzheimer’s diet and supplementation plan.

7. Could Improve Male Infertility

It’s possible CoQ10 can help improve fertility issues in men. In clinical trials, supplementation with coenzyme Q10 significantly:

  • Improved sperm motility (movement)
  • Increased fertilization rates
  • Boosted sperm count (especially when combined with selenium)
  • Improved sperm morphology (size/form)
  • Increased antioxidants in seminal plasma
  • Aided in treatment of asthenozoospermia (diagnostically low sperm motility)
  • Improved symptoms of Peyronie’s disease (a serious male infertility disease)

8. Helps Treat Symptoms of Fibromyalgia

Multiple clinical trials and case reports have found that CoQ10 may be a powerful natural method of treating fibromyalgia symptoms. In adults, the dosage was typically 300 milligrams per day, while one study on juvenile fibromyalgia focused on a 100 milligram dose.

Improvements included:

  • reduction of overall pain symptoms
  • less headaches
  • reduction of fatigue/tiredness
  • restored mitochondrial function
  • reduced oxidative stress
  • improvement in cholesterol markers (in the juvenile study)

COQ10 Foods

Coenzyme Q10 is found naturally in our diets from foods, including fish, liver, kidney and the germs of whole grain.

The richest natural sources of dietary coenzyme Q10 are meat, poultry and fish, but vegetarian options, such as beans, nuts, some vegetables, eggs and dairy products, are also helpful for increasing your intake.

Some of the best foods for supplying CoQ10 include:

  • Grass-fed beef
  • Herring
  • Free-range chicken
  • Rainbow trout
  • Sesame seeds
  • Pistachio nuts
  • Broccoli
  • Cauliflower
  • Oranges
  • Strawberries
  • Cage-free eggs
  • Sardines
  • Mackerel

The Institute of Medicine or other organizations have not yet published any particular dietary consumption recommendations for CoQ10.

Due to the fact that it is a fat-soluble antioxidant, it is best absorbed when combined with a little amount of healthy fats (just like vitamins E and A).

Many doctors advise taking supplements if you’re older or have a condition that would benefit from CoQ10 supplementation because, while it can be found in some foods, foods typically only give low quantities.

Deficit symptoms in the general population have not been extensively examined or reported on. The average person’s diet is thought to contribute about 25% of the body’s overall supply of CoQ10.

Eating a nutritious, diversified diet is the best way to get enough.

The best way to obtain enough is to eat a varied, nutrient-dense diet – plus to consider supplementing if it makes sense for your individual situation.

COQ10 Supplements and Dosage

COQ10 is found in such low quantities in most foods that even a healthy diet might be an impractical way to meet the daily recommended dosages. Taking a daily, high-quality CoQ10 supplement in capsule form (which helps with easier absorption into the bloodstream) can close the bridge between this gap.

CoQ10 Supplement Dosage:

Dosage sizes of CoQ10 dietary supplements range anywhere from 50–1,200 milligrams per day. Most supplements fall in the 100–200 milligram range.

Depending on the condition a person is attempting to treat, the CoQ10 dosage recommendations can range from 90 milligrams up to 1,200 milligrams. This larger dose has typically been used only to study the neurological benefits of CoQ10 — most successful studies use between 100–300 milligrams.

How much do CoQ10 dietary supplements typically cost, and how can you find a trustworthy brand?

Depending on the type and strength, 100 milligrams of coenzyme Q10 can cost anywhere from 8 cents to nearly $10 to $20.

Since CoQ10 is fat-soluble, it is best taken with a meal that contains fat, though it can be taken whenever it is most convenient. If you take more than 100 mg of CoQ10 per day, it is preferable to divide your dose into two or three smaller portions to aid in absorption.

CoQ10 can be taken with dinner because there is some indication that doing so may improve the body’s ability to utilise it. However, others claim that taking CoQ10 close to bedtime makes it difficult for them to fall asleep, so this comes down to individual preference.

Risks and Side Effects

What are the risks of taking CoQ10? Although it’s considered to be very safe overall and has been used in the medical field for many years, CoQ10 side effects may still affect some people.

Potential CoQ10 side effects can include:

  • Diarrhea
  • Nausea
  • Heartburn
  • Upper abdominal pain
  • Loss of appetite
  • Headaches
  • Insomnia
  • Rashes
  • Fatigue
  • Dizziness
  • Light sensitivity
  • Irritability

Always read the dosage instructions on the coenzyme Q10 pills you are taking, and follow them unless your doctor instructs you otherwise.

Those who shouldn’t use CoQ10 It’s usually recommended not to take CoQ10 supplements if you’re pregnant or nursing because it’s unclear whether or not these situations are safe for them.

Supplemental coenzyme Q10 can lessen the anticoagulant effectiveness of statins like warfarin and other widely used cholesterol-lowering drugs (such as those known as HMG-CoA reductase inhibitor statins). If you take these medications, discuss being monitored with your doctor.


  • CoQ10 is a natural substance found in the body and certain foods that helps fight oxidative stress and prevent tissue damage.
