Clinical Profile

Quick Reference

Scientific Rating
4.9
/ 5.0
Standardized Form
Ubiquinone or Ubiquinol (the reduced, more bioavailable form)

Coenzyme Q10 (CoQ10) is heavily concentrated in organs with high energy demands, such as the heart and liver. It acts as an obligate electron carrier in the mitochondrial electron transport chain. Endogenous production peaks in a person's twenties and steadily declines. Furthermore, statin medications notoriously block the mevalonate pathway, depleting systemic CoQ10 levels, which is a primary driver of statin-induced muscle pain (myopathy).

Clinical Summary

Extensively validated for managing statin-induced myopathy, improving ejection fraction in heart failure, and supporting male fertility.

Dosage Guidelines

100mg to 200mg daily, typically taken with a fat source to ensure absorption.

Safety & Side Effects

Exceptionally safe. Rare reports of mild insomnia if taken late in the day.

Known Interactions

Can mildly reduce the anticoagulant effect of warfarin due to its structural similarity to Vitamin K.
