CoQ10 (Ubiquinol)
Also known as: coenzyme Q10, ubiquinone, CoQ10, ubiquinol
Recommended Dosage
100–300 mg
Coenzyme Q10 is essential for mitochondrial energy production — it's a key component of the electron transport chain in every cell. Your body produces it naturally, but levels decline with age and are further depleted by statin medications. The ubiquinol form (reduced CoQ10) is better absorbed than ubiquinone, particularly as you age. The landmark Q-SYMBIO trial demonstrated significant reductions in cardiovascular mortality with supplementation.
TL;DR: Critical for mitochondrial energy production. Q-SYMBIO trial showed 43% cardiovascular mortality reduction in heart failure. Depleted by statins.
Evidence Rating: Grade A — Strong Evidence
Multiple high-quality RCTs, systematic reviews, or meta-analyses with consistent findings.
Forms Comparison
Ubiquinol
✓ High AbsorptionThe reduced, active form. Better absorbed, especially for people over 40 whose conversion ability declines.
Ubiquinone
~ Moderate AbsorptionThe oxidized form your body must convert to ubiquinol. Cheaper but less bioavailable with age.
Interaction Warnings
CoQ10 has vitamin K-like structure; may reduce anticoagulant effect. Monitor INR.
Statins deplete CoQ10 — supplementation recommended
Mild additive blood pressure lowering
⚠️ Important Notes
- Use ubiquinol form for better absorption (especially over 40)
- Essential if taking statins
- Mild energizing effect — take morning/early afternoon

Taurine
Grade B — Moderate EvidenceConditionally essential amino acid. Landmark 2023 Science paper showed it extends healthy lifespan in multiple species.
PQQ (Pyrroloquinoline Quinone)
Grade C — PreliminaryStimulates mitochondrial biogenesis (creation of new mitochondria). Best paired with CoQ10. Still early research.
NR (Nicotinamide Riboside)
Grade B — Moderate EvidenceNAD+ precursor with strong human RCT evidence for NAD+ elevation. Unique cardiovascular benefits: reduced arterial stiffness and blood pressure.
Astaxanthin
Grade C — PreliminaryExtremely potent antioxidant carotenoid. Promising for skin health and exercise recovery. Still building human evidence.
