Coenzyme Q10
Ubiquinone or ubiquinol, powder or oil: what coenzyme Q10 is, how the forms differ, how much a capsule holds and how to choose.
This substance has no health claim authorised in the European Union. So we describe what it is and how it is taken, but do not say what it does in the body.
What it is
Coenzyme Q10 is a fat-soluble substance the body makes itself; a little comes from meat, fish and nuts. It is present in almost every cell, most of all in organs that use a lot of energy.
Health claims for coenzyme Q10 were assessed in the European Union and not authorised. So we talk about forms and choice, but do not write what it does for the heart, energy or skin.
Ubiquinone and ubiquinol
Ubiquinone is the oxidised form, the most common and the least expensive. Ubiquinol is the reduced form; it costs more and must be protected from oxidation, so it is almost always sold in oil-filled softgels. Kaneka is a Japanese maker of raw material for both forms; its name often appears on the pack.
Coenzyme Q10 is fat-soluble, so oil-filled capsules and taking it with a meal are the usual practice.
How it is taken and how to choose
Capsules usually hold 30–200 mg; take as the pack directs, with a meal. Compare milligrams per daily dose and the price per 100 mg. People taking blood thinners or medicines for blood pressure or diabetes should ask a doctor first.
