Best CoQ10 and Ubiquinol Supplements Identified in Testing by ConsumerLab

White Plains, New York, September 11, 2021 — CoQ10 and ubiquinol, the active form of CoQ10, are often taken to offset a decline in natural levels that occurs with the use of statin (cholesterol-lowering) medication, and are also promoted for increasing energy and anti-aging effects. However, because CoQ10 and ubiquinol may not be well-absorbed, there are many different formulations available that claim to improve absorption and bioavailability. ConsumerLab recently purchased and tested many of these to check if they contained their claimed key ingredients.
