I beg to differ that the Ubiquinol version is "necessary". Better, perhaps, but not necessarily, necessary A family member with severe, complex pediatric-onset migraines (often associated with need for CoQ10) was put on a very absorbable ubiquinone from www.lef.org -- and it worked extremely well.

The family looked into ubiquinol after it hit the market, but failing to find a brand without soy, which the person is allergic to (there may now be one... anyone know of a brand without soy?), and seeing that what the person was on worked, just kept her on the "super absorbable ubiquinone."
