17 Dec 2020 --- BLS is drawing attention to a study finding D-Ribose and ubiquinol, a form of CoQ10, may positively impact mitochondrial function and help manage heart failure with preserved ejection fraction (HFpEF). A clinical trial from the University of Kansas Medical Center, US, found that combining D-Ribose with ubiquinol can contribute to myocardial ATP generation, which consequently may help to preserve cardiac muscles’ ejection fraction.
