What are the symptoms of needing CoQ10?


Coenzyme Q10, also known as CoQ10, is a vitamin-like substance that is produced naturally in the body. It plays an essential role in energy production and acts as a powerful antioxidant. Declining levels of CoQ10 have been linked to various symptoms and health conditions. Here is an in-depth look at the signs and symptoms that may indicate a need for CoQ10 supplementation.

What are the symptoms of needing CoQ10?

What is CoQ10?

CoQ10 is a compound made by the body and stored in the mitochondria, the powerhouses of cells. It is involved in making adenosine triphosphate (ATP), which is the energy currency of cells. CoQ10 exists in both oxidized and reduced forms. The reduced form is called ubiquinol.

CoQ10 acts as an electron carrier in the electron transport chain, shuttling electrons to kick start ATP synthesis. It also serves as an antioxidant, protecting cells from oxidative damage.

While our body can synthesize CoQ10 naturally, its production tends to decline with age. Our CoQ10 levels also go down when we are stressed or take certain medications like statins. CoQ10 deficiency can hamper energy production and interfere with vital body processes.

Supplementing with CoQ10 can help increase energy, improve heart health, and provide other benefits. Ubiquinol supplements may be better absorbed compared to ubiquinone supplements.

Symptoms of CoQ10 Deficiency

The following are some key signs and symptoms that may point to insufficient levels of CoQ10 in the body:

1. Fatigue and Low Energy

One of the most common symptoms of CoQ10 deficiency is fatigue or constantly feeling tired and sluggish. Since CoQ10 is essential for cellular energy production, low levels can translate to reduced energy.

Several studies have confirmed the beneficial effects of CoQ10 supplementation on fatigue and energy levels, especially in aging adults. A 2015 meta-analysis of 5 studies found that CoQ10 significantly decreased fatigue and increased energy in patients with chronic fatigue syndrome.

If you constantly feel lethargic despite getting adequate sleep and nutrition, consider getting your CoQ10 levels checked. Taking a CoQ10 supplement may help increase vitality and energy.

2. Muscle Weakness and Aches

CoQ10 is highly concentrated in heart muscles and skeletal muscles. Reduced CoQ10 can impair cellular energy metabolism in muscle tissue. This manifests in symptoms like muscle weakness, soreness or aching muscles.

A study on patients with fibromyalgia, who had muscle pain and fatigue, found that CoQ10 supplementation for 3 months reduced pain and tenderness in trigger points while boosting energy. Muscle weakness has also been reported in people taking statin medications which deplete CoQ10 reserves.

3. Brain Fog and Difficulty Concentrating

The brain is one of the most metabolically active organs in the body. It requires a constant supply of ATP energy to support its high energy demands. Low CoQ10 can diminish brain energy metabolism.

This manifests in symptoms like mental fatigue, cloudy thinking, problems focusing, and forgetfulness - classic signs of brain fog. Supplementing with CoQ10 may help clear up brain fog by powering energy production in brain cells.

A recent 2021 study found that medical students who took CoQ10 for 12 weeks significantly improved their memory, concentration and overall cognitive function compared to placebo. Another study showed CoQ10 could improve cognitive performance in the elderly.

4. Shortness of Breath

CoQ10 is highly concentrated in heart muscle cells which require tremendous amounts of energy to continuously pump blood throughout the body. Heart failure patients often have lower levels of CoQ10.

Some symptoms of a potential CoQ10 deficiency include shortness of breath especially with exertion, difficulty breathing when lying down, and waking up gasping for air. Several studies have shown CoQ10 supplementation can improve breathing difficulties and exercise capacity in people with heart failure.

5. High Blood Pressure

Studies show people with high blood pressure tend to have lower levels of CoQ10. This makes sense given its vital role in promoting cardiovascular health and improving cellular energy metabolism.

Clinical studies demonstrate that CoQ10 supplementation around 100-200 mg daily can help lower blood pressure in people with hypertension. A meta-analysis of 12 clinical trials found that CoQ10 could reduce both systolic and diastolic blood pressure.

If you have high blood pressure that is not well-controlled with medications, consider taking CoQ10 supplements to help normalize your blood pressure levels. But do not stop taking your regular blood pressure medications.

6. Heart Palpitations

Heart palpitations describe sensations like a racing, fluttering or pounding heart. Heart palpitations may be caused by CoQ10 deficiency which can impair energy metabolism in cardiac tissue.

Some clinical studies show that taking CoQ10 supplements helps reduce palpitations and improves heart rhythm in patients with mitral valve prolapse. Always consult a doctor if you experience frequent or prolonged heart palpitations.

7. Chest Pain

Angina or chest pain can also sometimes point to a potential CoQ10 deficiency. Impaired cellular respiration in heart muscles from low CoQ10 levels may trigger chest discomfort in some cases.

Some studies indicate that CoQ10 supplementation around 100-200 mg per day can help relieve chest pain and improve exercise tolerance in angina patients. But chest pain is a serious symptom that requires proper medical diagnosis.

8. High Cholesterol

CoQ10 is intimately involved in cellular energy metabolism which also encompasses cholesterol synthesis. Low CoQ10 levels may contribute to abnormal cholesterol profiles.

Some studies show that CoQ10 supplementation may modestly lower total and LDL cholesterol while raising HDL cholesterol. A meta-analysis of 12 clinical trials found that CoQ10 significantly decreased total cholesterol and triglycerides.

If you have high cholesterol, consider taking CoQ10 supplements in addition to making lifestyle changes and taking other natural remedies. But do not stop your cholesterol medications without consulting your doctor.

9. Headaches and Migraines

There is some evidence that decreased availability of CoQ10 and impaired mitochondrial function may play a role in certain types of headaches.

A few studies have shown that CoQ10 supplementation around 100-400 mg per day can help reduce headache frequency and severity in both adults and children. More research is still needed, but CoQ10 supplementation may benefit certain headache disorders.

10. Nausea and Vomiting

Feelings of nausea and vomiting may sometimes arise from cellular energy depletion. Loss of appetite, bloating, and intolerance to fatty foods can also signal low CoQ10 status.

One study found that giving CoQ10 supplements to patients on kidney dialysis significantly reduced nausea and vomiting compared to placebo. In another trial, CoQ10 therapy lessened digestive complaints linked to migraines.

11. Muscle Cramps and Statin Use

Taking statin drugs like atorvastatin and simvastatin to lower cholesterol can deplete CoQ10 reserves and cause statin-induced myopathy manifesting as muscle cramps, soreness or weakness.

Multiple studies demonstrate that supplementing with CoQ10 markedly improves statin-associated muscle symptoms and myopathy. CoQ10 restores depleted levels and supports energy metabolism in muscle mitochondria.

If you are on statin therapy and experience muscle cramps or weakness, talk to your doctor about adding CoQ10 supplements which may help resolve these symptoms.

12. Male Infertility and Fertility Issues

Sperm health and motility requires abundant cellular energy. Poor sperm quality in men can sometimes result from low CoQ10 levels.

Some research indicates taking CoQ10 supplements can improve sperm concentration, motility and fertilizing capacity in men affected by idiopathic infertility. CoQ10 therapy may also benefit women’s fertility though more evidence is needed.

13. Neurodegenerative Disorders

Impaired mitochondrial function and oxidative damage likely contributes to age-related neurodegenerative disorders like Parkinson’s and Alzheimer’s disease. Patients often display decreased CoQ10 levels.

Though more research is still needed, some studies suggest CoQ10 supplementation around 300-600 mg per day may offer neuroprotective benefits by supporting mitochondrial function in the brain and reducing oxidative stress.

14. Diabetes

Oxidative stress and inflammation promotes insulin resistance which underlies diabetes. As an antioxidant and anti-inflammatory, CoQ10 may help counteract these pathogenic processes.

Some clinical studies demonstrate CoQ10 supplementation can improve insulin secretion in the pancreas and enhance insulin sensitivity in the tissues of people with diabetes. It may also protect against diabetic kidney disease.

15. Hearing Problems and Tinnitus

The inner ear and auditory system have high energy demands and are especially vulnerable to mitochondrial dysfunction. Impaired cochlear blood flow can trigger hearing loss and tinnitus.

Human studies indicate that CoQ10 supplements around 100-300 mg per day can improve hearing thresholds, speech discrimination, and reduce the severity of tinnitus symptoms and noise-induced hearing loss.

16. Eye Disorders

The retina has a particularly high metabolic rate and reliance on healthy mitochondria to meet its substantial energy needs. Mitochondrial dysfunction is linked to retinal disease and age-related macular degeneration (AMD).

Supplementing with CoQ10 can enhance mitochondrial ATP production in retinal cells. Some studies suggest CoQ10 may benefit certain retinal disorders like AMD and diabetic retinopathy. More research is still underway.

Diagnosing CoQ10 Deficiency

There is no defined reference range for optimal serum CoQ10 levels. CoQ10 deficiency is usually suspected based on risk factors and symptoms rather than directly measuring CoQ10 levels in the blood. Testing is also costly and not widely available.

Some groups considered at risk for CoQ10 deficiency include:

  • Aging adults
  • Individuals with heart disease
  • People with high blood pressure
  • Those taking statin medications
  • Individuals with mitochondrial disorders
  • People with diabetes, neurodegenerative disease or fertility issues

Doctors may specifically test for CoQ10 deficiency in patients displaying treatment-resistant symptoms involving heart failure, encephalomyopathy, severe infantile multisystem disease, cerebellar ataxia or isolated myopathy.

Directly measuring CoQ10 levels can help confirm a deficiency. Serum CoQ10 concentration below 0.8 μg/mL is considered deficient. Healthy levels fall between 0.5 to 1.5 μg/mL. Supplementation is warranted if levels are very low.

Keep in mind that most symptoms of CoQ10 deficiency are often subtle and nonspecific and may have multiple contributing factors. Many doctors prescribe CoQ10 supplements empirically to alleviate certain symptoms rather than basing it on a confirmed deficiency.

Dosage for CoQ10 Deficiency

There is no established Recommended Dietary Allowance (RDA) for CoQ10 intake. Supplements are available over-the-counter in strengths ranging from 30 mg to 200 mg.

The optimal therapeutic dosage can vary widely based on the individual and condition being treated. Those with CoQ10 deficiency may need higher daily doses between 100 to 300 mg.

Some studies utilized even higher amounts between 300 to 2,400 mg daily but only under medical supervision. It is best to consult a health practitioner to determine the appropriate CoQ10 dosage based on your specific health status.

Divide your daily CoQ10 into 2 to 3 smaller doses taken with meals to enhance absorption. Ubiquinol form may be better utilized than ubiquinone form, especially as we age.

Additionally, take CoQ10 supplements alongside fats or oils to boost absorption. Avoid high doses of over 200 mg per day without medical guidance. Seek professional input before using CoQ10 for children.

Food Sources of CoQ10

While our body synthesize CoQ10, you can also obtain small amounts from your diet. However, food sources only provide around 3 to 5 mg of CoQ10 daily.

Some of the best dietary sources include:

  • Organ meats like heart, kidney and liver
  • Grass-fed beef and bison
  • Fatty fish like mackerel, herring, trout and sardine
  • Nuts and seeds like pistachios, sesame seeds and peanuts
  • Spinach, broccoli and cauliflower
  • Eggs and dairy products
  • Soybean and rapeseed oils
  • Fruits like oranges, strawberries and avocados

Keep in mind that typical CoQ10 production decreases substantially as we age. Older adults would likely benefit from more reliable CoQ10 intake from supplements.

Factors like food processing, cooking and aging can also deplete up to 98% of CoQ10 content in foods. Hence, supplementation becomes more important to overcome any deficiencies, especially as we grow older.

Potential Side Effects of CoQ10

CoQ10 supplements are well tolerated by most people at commonly recommended dosages. Adverse effects are rare but may include:

  • Upset stomach, nausea, diarrhea
  • Loss of appetite
  • Insomnia and overstimulation
  • Fatigue
  • Skin rashes (seldom)
  • Headaches (uncommon)

High doses above 300 mg per day might increase risk of adverse effects. Seek medical guidance before exceeding 200 mg daily, particularly if you have any underlying health conditions or take any medications.

CoQ10 supplements may interact with blood thinners like warfarin and antidepressant medications. Consult a doctor before using CoQ10 if you take any prescription medications or have surgery scheduled.

Otherwise, CoQ10 is very safe at typical dosages and few side effects are reported. It may take 2 to 3 months of continued use to experience benefits. Pick an established reputable brand and seek professional advice on the appropriate dosage.

Signs You May Need CoQ10

Some key takeaways from the symptoms and health conditions linked to CoQ10 deficiency include:

  • Fatigue, weakness and muscle aches
  • Brain fog, difficulty concentrating
  • Shortness of breath and chest pain
  • High blood pressure and cholesterol
  • Headaches and visual problems
  • Nausea, bloating and gut issues
  • Muscle cramps with statin use
  • Infertility and hormonal imbalances
  • Diabetes and metabolic disorders
  • Neurodegenerative disorders
  • Hearing loss and tinnitus

While more research is still needed, correcting an underlying CoQ10 deficiency may help alleviate some of these symptoms. A blood test can confirm low levels.

Supplementing with CoQ10 boosts energy metabolism, acts as a potent antioxidant, improves heart and brain health, and offers other benefits. Consult a doctor to determine if CoQ10 supplementation may be useful in your situation.

What are the symptoms of needing CoQ10? Conclusion

In summary, CoQ10 is a substance vital for cellular energy production and antioxidant protection. Declining levels can translate into various symptoms involving fatigue, muscle and brain function, cardiovascular health, and more.

Measuring CoQ10 levels directly can confirm a deficiency, especially in high-risk groups like the elderly and chronically ill. Doctors may then prescribe CoQ10 supplementation to help replenish levels.

Doses between 100 to 300 mg daily, in divided doses with food and oils, are commonly used. Those with deficiency may require higher end doses under medical guidance. Ubiquinol form may be better absorbed.

While food sources only provide small amounts, eating organ meats, fatty fish, eggs, seeds and vegetable oils can somewhat boost dietary CoQ10 intake.

CoQ10 supplements are safe, well-tolerated and may help alleviate certain symptoms. But optimal use requires an individualized approach based on specific health conditions and needs. Consult a healthcare professional to determine if CoQ10 supplementation may be beneficial for you.
