Co-Q10 is found in energy-rich tissues like the heart and supports mitochondrial health and energy production, the health benefits of which support cardiovascular function.* Ubiquinol, the reduced, active, antioxidant form of Co-Q10 is significantly better absorbed than regular Co-Q10. Jarrow Formulas’ proprietary QH-absorb® formula has been shown clinically in humans to increase Co-Q10 levels by 222% (100 mg per day) and by 777% (300 mg per day) over baseline.
