Earlier research indicated that therapeutic blood levels of coenzyme Q10 should be at least 2.5 µg/mL to elicit a biosensitive result (2). In Khatta and colleagues' study, 19 of 22 patients had blood levels lower than this minimal amount. In another investigation, optimum improvement in myocardial function occurred with an average blood level of 2.9 µg/mL (3). When higher blood levels are obtained (>3.5 µg/mL), subjective or objective ...References1. Khatta M, Alexander BS, Krichten CM, Fisher ML, Freudenberger R, Robinson SW, et al .
