Ingredient guide
Coenzyme Q10, or CoQ10, is a vitamin-like compound made by the body and used in cell energy production. Its best-studied supplement use is easing muscle aches in people taking statins, with moderate evidence. Sold as ubiquinone or the better-absorbed ubiquinol.
Moderate evidenceCoenzyme Q10 is a vitamin-like compound found in nearly every cell of the body. It sits inside the mitochondria, the cell's power plants, where it carries electrons along the chain that produces energy. You get a little from food, mostly meat and fish, and your body makes the rest. Supplements come as ubiquinone, the oxidised form, or ubiquinol, the active reduced form.
Two roles drive the interest. CoQ10 is essential for energy production, so cells that use a lot of energy, like heart and muscle, rely on a steady supply. It also acts as a fat-soluble antioxidant. Statins lower cholesterol but also lower CoQ10 levels in the blood, which is the basis for using it to ease statin-linked muscle aches.
The most-tested use is statin-associated muscle symptoms. A systematic review of randomised trials and several meta-analyses report that CoQ10 supplementation eased the muscle pain that some people get on statins, with the clearest results at around 100 mg per day for mild-to-moderate symptoms. The evidence is not perfect, but the supplement is well tolerated, so a trial is reasonable for people in that situation.
Outside statin muscle symptoms, CoQ10 is studied in heart failure, blood pressure, and migraine, with smaller or mixed effects. We grade the overall human evidence as moderate. Its single strongest use today is statin muscle support, with broader claims more uncertain. Ubiquinol may absorb better in older adults, though the head-to-head data is limited.
The common starting point is 100 mg per day with a fat-containing meal, since absorption is poor on an empty stomach. For statin muscle aches, 50 mg twice daily has been studied. Ubiquinol may suit older adults better. Because CoQ10 can interact with warfarin and blood pressure medicine, check with your healthcare provider before starting.
Most trials use 100 mg to 200 mg per day, often split with meals to aid absorption. For statin muscle aches, 50 mg twice daily has been studied. Take it with a fat-containing meal. Ask your healthcare provider before adding it if you take blood thinners or blood pressure medicine.
Several controlled trials and meta-analyses suggest it can ease mild-to-moderate muscle pain linked with statins, often at around 100 mg per day.
Ubiquinol is the active form and may absorb better, especially in older adults. For most younger people, ubiquinone is cheaper and works fine.
With a meal that contains some fat. Absorption is much better with food than on an empty stomach.
It can interact with warfarin and mildly lower blood pressure, so check with a doctor or pharmacist if you take those medicines.
