How much Coenzyme Q10 (CoQ10) should I take daily?

Coenzyme Q10 (CoQ10) is a substance that occurs naturally in the body and plays a critical role in the production of energy in cells. It has been studied for its potential benefits in various health conditions and as a dietary supplement.

CoQ10 is well tolerated at high doses, with a study showing safety at doses as high as 3,000 mg/day for ALS patients.
Supplementation with CoQ10 can significantly increase serum concentrations, with 30 mg or 100 mg daily doses resulting in median increases in serum CoQ10 concentration of 0.55 mg/l and 1.36 mg/l, respectively.
The observed safe level (OSL) risk assessment method indicates that intakes up to 1200 mg/day are considered safe, with no significant adverse effects reported at this level.
Clinical trials on muscular dystrophies and neurogenic atrophies suggest that a daily dose of 100 mg CoQ10 is effective and safe, though it may be considered a low dose.
A meta-analysis suggests that daily supplementation of 300-400 mg CoQ10 shows superior inhibition of inflammatory factors, indicating this range may be optimal for anti-inflammatory effects.

In conclusion, CoQ10 supplementation is generally safe and well-tolerated across a range of doses. Studies have shown that daily doses from 30 mg to as high as 3,000 mg can be safe, with an observed safe level up to 1200 mg/day. For specific conditions like muscular dystrophies, a dose of 100 mg daily has been found to be effective, while for anti-inflammatory effects, a higher dose range of 300-400 mg daily may be optimal. It is important to note that the appropriate dosage may vary depending on individual health conditions and goals, and it is advisable to consult with a healthcare provider before starting any new supplement regimen.

Summary

Sources and full results

Tolerance of high-dose (3,000 mg/day) coenzyme Q10 in ALS

High doses of coenzyme Q10 (3,000 mg/day) are safe and well-tolerated in ALS patients, potentially improving mitochondrial dysfunction and promoting recovery.

Serum coenzyme Q10 concentrations in healthy men supplemented with 30 mg or 100 mg coenzyme Q10 for two months in a randomised controlled study

Supplementing with 30 or 100 mg coenzyme Q10 for two months significantly increased serum Q10 concentrations, with the 100 mg dose showing a greater increase than the 30 mg dose.

Risk assessment for coenzyme Q10 (Ubiquinone).

Coenzyme Q10 is safe at doses up to 1200 mg/day, with no dose-response relationship for adverse effects, and data for higher doses is insufficient for a confident conclusion of safety.

Two successful double-blind trials with coenzyme Q10 (vitamin Q10) on muscular dystrophies and neurogenic atrophies.

Coenzyme Q10 (vitamin Q10) treatment improves physical performance in patients with muscular dystrophies and neurogenic atrophies, but a dosage of 100 mg daily is too low for long-term use.

Efficacy and optimal dose of coenzyme Q10 supplementation on inflammation-related biomarkers: A GRADE-assessed systematic review and updated meta-analysis of randomized controlled trials.

Daily supplementation of 300-400 mg CoQ10 effectively reduces inflammatory mediators in the general population.

Progress on therapy of breast cancer with vitamin Q10 and the regression of metastases.

Vitamin Q10 therapy, involving daily oral doses of 390 mg, can effectively reduce metastases in breast cancer patients, potentially improving overall health.

Coenzyme Q10 in the diet--daily intake and relative bioavailability.

Dietary coenzyme Q10 is present in food items and absorbed to a significant degree, contributing to the plasma coenzyme Q10 concentration.

Bioavailability and Sustained Plasma Concentrations of CoQ10 in Healthy Volunteers by a Novel Oral Timed-Release Preparation

The novel oral timed-release preparation (COQUN®) effectively maintains high constant blood concentrations of CoQ10 in healthy volunteers, potentially offering a new antioxidative treatment for chronic diseases.

Safety and tolerability of high‐dosage coenzyme Q10 in Huntington's disease and healthy subjects

High-dosage coenzyme Q10 is well-tolerated and may provide the best balance between tolerability and blood levels in Huntington's disease and healthy subjects.

Muscle and plasma coenzyme Q10 concentration, aerobic power and exercise economy of healthy men in response to four weeks of supplementation.

CoQ10 supplementation in healthy men showed no significant changes in muscle concentration, VO2max, ventilatory threshold, exercise economy, or oxygen deficit, possibly due to the mitochondrial membrane being saturated or the exercise testing protocol being insufficiently sensitive.
