The most bioavailable and active form of Co-Q10, High absorption natural proliposome delivery system. Ubiquinol is the reduced (active antioxidant) form of Co-Q10, the form which is directly used in human metabolism as a lipid-soluble antioxidant. While standard Co-Q10 (ubiquinone) supplements can be activated in the body, this activation can be less efficient in some individuals, based on age or genetics. Ubiquinol also has superior bioavailability to ubiquinone, as demonstrated in clinical trials.QH-absorb utilizes the Q-absorb natural proliposome lipid-soluble delivery system, which has been clinically shown in humans to increase Co-Q10 levels up to 400% (3.2x) over baseline and is 3-4 times better absorbed than chewable Co-Q10 tablets. Co-Q10 supports heart function as a component of the electron transport system, and as an antioxidant protects mitochondrial membranes and cholesterol from oxidation.Jarrow FORMULAS ubiquinol is derived from Co-Q10 that is maufactured via a yeast-fermentation process and consists only of the natural trans configuration, the same as is biosynthesized by humans. Jarrow FORMULAS supports clinical research on Coenzyme Q10.
