Supplement Comparison
CoQ10 is the body's primary mitochondrial antioxidant — required for ATP production. The form (ubiquinone vs ubiquinol) and the dose (100 mg vs 300 mg) make a 2-3x difference in bioavailability, especially for adults over 50 and statin users. This page ranks 7 popular CoQ10 products.

Absorption: 3/5 · GI tolerance: 5/5
Cheapest per mg. The most studied form (most RCTs). Stable on shelf for years. Most clinical evidence for cardiovascular outcomes (Mortensen 2014 used ubiquinone).
Lower bioavailability in adults >50 — the body must convert ubiquinone to ubiquinol to use it, and conversion efficiency drops with age.
Best for: Adults <50, cardiovascular support, anyone on a budget, when 200-300 mg/day is achievable.
Absorption: 5/5 · GI tolerance: 5/5
2-3x more bioavailable per Witte 2015. The active reduced form — no conversion needed. Better for adults >50 whose conversion is impaired.
More expensive per mg. More prone to oxidation on shelf (check expiry dates).
Best for: Adults >50, anyone with documented deficiency, anyone who took ubiquinone without benefit, mitochondrial conditions.
The conversion question: Ubiquinol is the active, reduced form that the body actually uses. Ubiquinone is the oxidized form that the body must convert to ubiquinol before use. Healthy adults under 50 convert ubiquinone efficiently. Adults over 50, people with chronic illness, and people on statins have impaired conversion per Witte 2015 — they benefit more from ubiquinol per mg.
There is no RDA for CoQ10 — the body synthesizes it. Therapeutic doses vary widely by indication. The doses below are evidence-based ranges from the cited RCTs.
| Indication | Dose (mg/day) | Form |
|---|---|---|
| Statin users (deficiency correction) | 100-200 | Ubiquinone or ubiquinol |
| Heart failure (chronic) | 300 | Ubiquinone (per Mortensen 2014) |
| Cardiovascular support (general) | 100-200 | Either form |
| Fertility (male sperm quality) | 200-400 | Ubiquinol preferred |
| Migraine prevention | 300 | Ubiquinone (per PMID 26877823) |
| Healthy adults <50 | 50-100 (optional) | Ubiquinone (cheapest) |

CoQ10 is one of the safest supplements, with mild side effects at recommended doses. The main consideration is warfarin interaction.
Statin + CoQ10 combination: statins (atorvastatin, rosuvastatin, simvastatin) inhibit the same pathway that produces endogenous CoQ10. Langsjoen 2008 documented that statin users have 25-50% lower serum CoQ10, contributing to muscle pain and fatigue. The standard of care for statin users per the Mayo Clinic and Cleveland Clinic is to co-supplement with 100-200 mg CoQ10 daily.
