Active-Q is different - it is Kaneka QH Coq10 that is stabilized with Tishcon's patented process to guarantee 100% Ubiquinol content! So if you want the most potent Ubiquinol Q10 available, you want the 100% Ubiquinol Coenzyme Q10 - you want Active-Q Most commercially available CoQ10 uses Ubiquinone - the fully oxidized form of Coenzyme Q10. However, research, (in animals and humans), has shown Ubiquinol to be absorbed better than Ubiquinone in fact, more than 90% of the circulating CoQ10 in our body is present as Ubiquinol. Active-Q uses Ubiquinol the active antioxidant form of Coenzyme Q10 and is now available in a new 100mg per softgel dosage. Why weren't Ubiquinol soft gels as available as the Ubiquinone form of CoQ10 in a soft gel? The problem was stability and it was only recently solved by Kaneka Corp of Japan. That breakthrough solution, Kaneka QH Ubiquinol, is now utilized in the new Bio-Q-Sorb Active from Tishcon Corp in the new, stronger 100mg per softgel dosage size.
