CoQ10 / Ubiquinol
Essential cofactor in mitochondrial electron transport chain. Levels decline with age and statin use. Ubiquinol is the reduced (active) form.
Evidence by Outcome
All-cause Mortality
32% reduction in all-cause mortality (RR=0.68, 95% CI 0.49–0.94). JACC 2022 meta-analysis of 884 RCTs.
Fatigue Reduction
Hedges' g = -0.398 (95% CI -0.641 to -0.155, p=0.001). Dose-response: higher dose → greater effect. Front Pharmacol 2022.
Heart Failure
43% reduction in major cardiac events (Q-SYMBIO trial, 300mg/day)
Statin Side Effects
Reduced statin-associated myopathy symptoms
Blood Pressure
-11 mmHg systolic (Cochrane review)
Dosing Guide
100-200mg/day
With fat-containing meal
Ubiquinol absorbs 2-8x better than ubiquinone. Over 40, ubiquinol preferred due to declining conversion.
Safety Profile
Possible Side Effects
- • Mild GI discomfort
- • Insomnia if taken late
Contraindications
- ⚠ May reduce warfarin efficacy
- ⚠ Consult before surgery
Known Interactions
Both fat-soluble — take together with a fatty meal for optimal absorption.
Source: General pharmacokinetic principle
NMN boosts NAD+ for electron transport; CoQ10 is a direct electron carrier in the same chain. Complementary mitochondrial support.
Source: Mechanistic rationale
Omega-3 reduces inflammation; CoQ10 supports mitochondrial energy. Both cardiovascular protective. Take together with fat.
Source: Mechanistic reasoning + both fat-soluble
Both support ATP production through different mechanisms. CoQ10 in electron transport, creatine in phosphocreatine shuttle.
