CoQ10 200 mg

Ubiquinone, the oxidized form, printed on the panel as Coenzyme Q-10 (Ubiquinone) 200 mg. It is not ubiquinol. Two small trials compared the forms on blood levels only and disagree, so we do not say either one is better absorbed.

One capsule once a day, 20–30 minutes before a meal, or as directed by your healthcare professional. CoQ10 is fat-soluble and our capsule is a plain powder with no oil; we found no human trial of taking ubiquinone before versus with a meal, so we say nothing about absorption.

The studies that reported effects used 300 mg a day, 1.5 times our 200 mg, and their abstracts did not say whether the CoQ10 was ubiquinone or ubiquinol. A 2006 safety review covered 60 to 1,200 mg a day and found no dose-related side effects in that range. We make no benefit claim at 200 mg.

Ask a physician before use if you are pregnant or nursing, under 18, take any medication (especially blood thinners) or have a medical condition. A small trial of 100 mg a day in 24 people on a stable blood thinner found no change, but that is half our dose, and earlier case reports described the opposite.

No. It is a powder-filled hypromellose capsule with rice flour. In a 10-person trial from 1994, an oil-based softgel was absorbed better than a powder capsule, so formulation can matter. We have no absorption data on this product.
