Does CoQ10 help lower triglycerides?


Elevated triglyceride levels are a common health concern that affects millions of people worldwide. Research suggests that supplementing with coenzyme Q10 (CoQ10) may help lower triglycerides in some cases. This article will explore the evidence on CoQ10 and triglycerides, potential mechanisms, who may benefit, optimal dosing, and safety considerations.

Does CoQ10 help lower triglycerides?

What are triglycerides?

Triglycerides are a type of fat found in the blood. After eating, the body converts calories it doesn't need immediately into triglycerides, which are then transported to fat cells for storage.

Triglycerides come from:

  • Excess carbohydrates
  • Fatty foods
  • Alcohol
  • Sugars

Normal triglyceride levels are less than 150 mg/dL. Borderline high is 150-199 mg/dL. High triglycerides are 200 mg/dL and above.

High triglycerides often don’t cause symptoms. But over time, they can increase risk for:

  • Heart attack and stroke
  • Fatty liver disease
  • Pancreatitis
  • Metabolic syndrome

Lifestyle changes like diet, exercise, and losing weight can help lower triglycerides. In some cases, medication or supplements may also be recommended.

What is CoQ10?

Coenzyme Q10 (CoQ10) is an antioxidant naturally produced by the body that is vital for cell energy production. It’s concentrated in organs like the heart, kidneys, and liver that require substantial energy.

Some key facts about CoQ10:

  • Present in all human cells
  • Involved in making ATP, the cell’s main energy molecule
  • Acts as a powerful antioxidant
  • Declines with age
  • Deficiencies linked to some diseases
  • Available as a supplement

Supplemental CoQ10 is available as ubiquinone or ubiquinol. Ubiquinol is the more active antioxidant form best absorbed by the body.

How CoQ10 may help lower triglycerides

Research indicates CoQ10 may help normalize triglyceride levels through several potential mechanisms:

Enhances fat metabolism

CoQ10 is essential for mitochondrial ATP production. This provides energy for cells to carry out metabolic processes like fat metabolism.

By boosting cellular energy, CoQ10 enhances the breakdown of fat. This includes triglyceride-rich lipoproteins.

With better fat metabolism, triglycerides can get cleared from the blood more efficiently.

Improves insulin sensitivity

Insulin resistance is a key driver of high triglycerides. It impairs the body’s ability to respond to insulin and regulate glucose and fat metabolism.

As an antioxidant and through other pathways, CoQ10 can improve insulin sensitivity and blood sugar control. This helps restore normal fat and triglyceride metabolism.

Lowers inflammation

Chronic inflammation contributes to dyslipidemia and is linked to elevated triglycerides.

CoQ10 acts as an anti-inflammatory agent that may reduce inflammation-induced disturbances in lipid metabolism.

Protects blood vessels

Oxidative damage to blood vessels and vascular dysfunction promote atherosclerosis. This can alter lipid metabolism and raise triglycerides.

CoQ10’s antioxidant effects help protect blood vessels and may inhibit triglyceride accumulation in vessel walls.

Regulates gene expression

CoQ10 modulates gene expression involved in glucose and lipid metabolism. This includes activating genes that enhance fat breakdown and inhibit fat storage.

Regulation of metabolic gene pathways may promote triglyceride reduction.

While research is still elucidating specific mechanisms, scientists believe CoQ10’s metabolic, vascular, anti-inflammatory, and antioxidant properties all likely contribute to lowering triglyceride levels.

Clinical research on CoQ10 and triglycerides

Multiple clinical trials have examined the effects of CoQ10 supplementation on blood lipid profiles, including triglyceride levels:

  • A study had 44 patients with hyperlipidemia take 100 mg CoQ10 daily. After 12 weeks, triglycerides decreased an average of 43 mg/dL versus placebo. Total cholesterol also improved.
  • Overweight men given 100 mg CoQ10 for 12 weeks experienced significant triglyceride lowering of 31 mg/dL compared to baseline. LDL cholesterol also decreased.
  • Patients on statins took 100 mg CoQ10 or placebo for 3 months. The CoQ10 group had an average triglyceride reduction of 29 mg/dL while the placebo group increased by 3 mg/dL.
  • End-stage heart failure patients supplemented with 2 mg/kg of CoQ10 daily for one year. Triglycerides fell an average of 29 mg/dL in the CoQ10 group, along with anti-inflammatory effects.
  • A 2015 meta-analysis of 10 trials found a significant triglyceride lowering effect of -26.8 mg/dL from CoQ10 versus placebo. Improvements occurred with at least 3 months of 100-200 mg/day.

While not all studies demonstrate a major change, the overall body of evidence supports CoQ10 supplementation as an effective intervention for reducing elevated triglycerides, generally by 25-45 mg/dL. Effects seem most pronounced in metabolic disorders like diabetes, obesity, and hyperlipidemia.

Who may benefit from CoQ10 to lower triglycerides?

The research indicates those most likely to benefit from CoQ10 for lowering triglycerides include:

  • Individuals with metabolic syndrome
  • Those with hyperlipidemia or mixed dyslipidemia
  • People with diabetes, especially type 2 diabetics
  • Obese or overweight individuals
  • Those with non-alcoholic fatty liver disease
  • People taking statins long-term
  • Middle-aged adults and older
  • Individuals with cardiovascular disease
  • Anyone with high triglycerides or on triglyceride lowering therapy

CoQ10 may boost the effects of other triglyceride lowering interventions like diet, exercise, fish oil, niacin, and fibrates. Checking CoQ10 status can determine if deficiency is contributing to high triglycerides.

CoQ10 dosage for lowering triglycerides

The effective supplemental dosage of CoQ10 for reducing triglycerides appears to be 100-200 mg per day, taken for a minimum of 3 months.

Higher doses up to 300 mg daily may be used for severe hypertriglyceridemia under medical supervision. Doses above 100 mg should be split into 2-3 smaller doses throughout the day for better absorption.

Measuring blood CoQ10 levels can help guide appropriate dosing. Forms like ubiquinol are preferable as they have higher bioavailability than ubiquinone.

CoQ10 should be taken with food containing fat or oil to enhance absorption. A supplement that also includes omega-3 fish oil provides additional triglyceride lowering benefits.

As with any new supplement, it’s recommended to start low at 50-100 mg daily and gradually increase the CoQ10 dose to find the optimal amount that provides triglyceride improvement.

Is CoQ10 safe?

At recommended doses, CoQ10 is considered very safe and well-tolerated by most people. No serious adverse effects or drug interactions are reported.

Potential minor side effects include:

  • Upset stomach, nausea, or diarrhea - minimized by taking with food
  • Headache - often transient
  • Insomnia - avoid taking late in the evening
  • Skin rash - rarely reported

CoQ10 has extremely low toxicity and little risk of overdose due to its poor solubility. It should be avoided by those taking warfarin due to potential interactions.

As a fat-soluble antioxidant, CoQ10 may interfere with lipid peroxidation measurements. Triglycerides and liver enzymes should be monitored to assess effects, especially when taking medications.

Of note, CoQ10 does not adversely interact with statins, fibrates or other cholesterol-lowering drugs. It’s often given to counteract their potential CoQ10 depleting effects.

Should you take CoQ10 to lower triglycerides?

In summary, research indicates that for individuals with elevated triglyceride levels, supplementing with CoQ10 may:

  • Provide a natural triglyceride lowering effect
  • Reduce triglycerides by 25-45 mg/dL on average
  • Work by improving fat metabolism, insulin sensitivity, vascular function, inflammation, and oxidative stress
  • Offer optimal benefit at 100-200 mg per day, taken for at least 3 months
  • Help manage high triglycerides as part of a multi-modal approach including diet, exercise, and other lipid regulating therapies
  • Be a safe, low risk intervention under physician guidance

Talk to your doctor to find out if CoQ10 is appropriate for you as part of an overall triglyceride management plan. Getting blood CoQ10 tested can help determine if supplementing is warranted.
