Found an interesting blog article about the Ubiquinol/Ubiquinone controversy of CoQ10. It's long but an eye-opening read. It also could save someone money if they take CoQ10 supplements.
I especially found this part of the article interesting:
"• Clinical studies with Ubiquinol show it is superior to Ubiquinone. FABRICATION
In fact, Ubiquinol became available in 2006 and to date, no clinical studies in human beings using Ubiquinol have been published in the peer-reviewed scientific literature. An anti-aging study in genetic mutated mice has been described, but the role of the genetic mutations in these mice as they pertain to CoQ10 conversion are not understood. This is a concern since mice use CoQ9 as an energizer and antioxidant whereas human beings use CoQ10."
