CoQ10 Supplements
Coenzyme Q10 (CoQ10) is a fat-soluble, vitamin-like compound found in virtually every cell in the body. It plays a central role in the mitochondrial electron transport chain, where it is essential for the production of ATP — the primary energy currency of the cell. CoQ10 also functions as a potent antioxidant, helping to protect cell membranes and mitochondria from oxidative damage. The body produces CoQ10 naturally, but production declines with age and can be further reduced by certain medications, including statins.
At Best Vitamins Online, we carry CoQ10 supplements from professional-grade brands including NOW Foods, Bluebonnet Nutrition, Douglas Laboratories, Thorne, and Pure Encapsulations. Both ubiquinone and ubiquinol forms are available across a range of potencies.
CoQ10 Forms: Ubiquinone vs. Ubiquinol
- Ubiquinone — The oxidized, classic form of CoQ10; the most widely studied and used form; must be converted to ubiquinol in the body to be active
- Ubiquinol — The reduced, active antioxidant form of CoQ10; does not require conversion; may be preferred for older adults or those with conditions that impair conversion
- CoQ10 with BioPerine — Formulas combining CoQ10 with black pepper extract (piperine) to enhance absorption
- CoQ10 in Oil-Based Softgels — Fat-soluble CoQ10 is best absorbed when delivered in an oil base; softgel formats are designed to optimize bioavailability
- High-Potency CoQ10 (200–600 mg) — Higher-dose formulas for those with greater supplementation needs

Frequently Asked Questions
What is the difference between ubiquinone and ubiquinol?
Ubiquinone is the oxidized form of CoQ10 and is the most extensively researched. The body converts ubiquinone to ubiquinol, the active antioxidant form. Ubiquinol is already in its reduced, active state and does not require conversion. For most healthy adults, ubiquinone is effective and well-studied. Ubiquinol may be a better choice for older adults or those whose bodies may have reduced conversion capacity.
Should I take CoQ10 with food?
Yes. CoQ10 is fat-soluble and is significantly better absorbed when taken with a meal containing dietary fat. Oil-based softgel formulas are specifically designed to enhance absorption, but taking any CoQ10 supplement with food will improve bioavailability compared to taking it on an empty stomach.
Why do people taking statins often supplement with CoQ10?
Statin medications work by inhibiting the HMG-CoA reductase enzyme, which is involved in both cholesterol and CoQ10 synthesis. As a result, statin use can reduce the body's natural CoQ10 production. Many healthcare providers recommend CoQ10 supplementation for individuals on statin therapy. Always consult your healthcare provider before starting any new supplement.
What potency of CoQ10 should I take?
Common supplemental doses range from 100–300 mg per day for general use. Higher doses (400–600 mg) are sometimes used under healthcare provider guidance. The right potency depends on your individual health status, age, and goals — consult your healthcare provider for personalized recommendations.
