What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Coenzyme Q10 is an antioxidant most often used for heart health, cellular energy, statin side effect mitigation. NutriStack rates the overall evidence as strong. A typical adult dose is 100–300 mg daily, commonly taken as ubiquinol (reduced, active form; better for age 40+) or ubiquinone. This profile indexes 21 sources.
The bottom line
Evidence rating strong. Most-documented uses: heart health, cellular energy, statin side effect mitigation. 21 sources indexed (2005–2025), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Shuttles electrons between Complex I/II and Complex III in the mitochondrial electron transport chain for ATP production. As ubiquinol (reduced form), acts as a potent lipid-soluble antioxidant protecting cell membranes and LDL cholesterol from oxidation. Regenerates vitamin E.17
Dosing & protocol.
Fat-soluble; take with fatty meal. Ubiquinol may be moderately better absorbed (~1.5-2x), especially in older adults, but the difference is formulation-dependent.7,9
What it actually costs.
Real-world pricing across three quality tiers. Assumes Ubiquinone.
Assumes about 100-200 mg/day. Plain ubiquinone usually offers the lowest entry price for CoQ10 support. Updated 2026-04-02.
The same dose, as food.
How much you'd eat to match a supplemental dose.
Supplemental CoQ10 doses are much higher than realistic food intake.
Food still contributes, especially from organ meats and oily fish.
