As a long-time Coenzyme Q10 researcher, I worry that consumers will be persuaded by these misleading marketing claims. In this article, I want to give some background information about how the Coenzyme Q10 in supplements is absorbed and transferred in the body.

Regardless of whether the supplement manufacturer chooses to work with ubiquinone or ubiquinol, he or she must deal with the following problems [Judy 2018]:
