- What are the health benefits of CoQ10 and ubiquinol? People often take CoQ10 to offset a decline in natural levels that occurs with the use of statin (cholesterol-lowering) medication. Some take it to feel more energized or for a variety of other purposes. It may also modestly help with elevated cholesterol levels, migraine, and other conditions. The evidence supporting these uses remains preliminary, although it does benefit people with congestive heart failure (see What It Does). After being absorbed into the body, more than 90% of CoQ10 is converted to its active form, known as ubiquinol (CoQH2-10), which is also available as a supplement and appears to have greater bioavailability (i.e., it raises blood levels more) (see What It Is).
- How much CoQ10 or ubiquinol should I take? CoQ10 and ubiquinol are typically taken at a dose of 50 to 200 mg per day, although higher doses have been used (see Dosage).
- What did CL's tests of CoQ10 show? In laboratory testing, all of the products were shown to provide their listed amounts of CoQ10 or ubiquinol, which is an improvement over the results of our previous review. Cost comparisons, based on a 100 mg dose, showed you could spend as little as 8 cents to over $6 for an equivalent amount of CoQ10, and from 34 cents to $1.18 for ubiquinol (See What CL Found).
- Best CoQ10 supplement? Among 33 CL Approved products, CL selected several Top Picks for regular as well as bioavailability-enhanced CoQ10 and ubiquinol supplements, each providing high quality CoQ10 or ubiquinol at very good value.
- How to take CoQ10? Gastrointestinal side-effects may occur but can be minimized by breaking up the dose throughout the day, although it may interfere with sleep if taken before bed. CoQ10 and ubiquinol are best absorbed when taken with or shortly after a fatty meal, although certain forms can be taken without fats (see Absorption and Bioavailability Enhancers).
- CoQ10 safety and side effects: At typical doses, CoQ10 and ubiquinol appear to be generally safe, but there are possible interactions with blood thinners and diabetes medications (see Concerns and Cautions).
