Studies show that when we are young, our bodies synthesize CoQ10 well, converting it readily to Ubiquinol. But as we get older, the body's ability to convert CoQ10 to Ubiquinol diminishes. This means that as we age, CoQ10 supplements may become less effective. Our Extra Strength Qunol Ubiquinol is different from other CoQ10 supplements. It contains CoQ10 that has already been converted to its antioxidant form, Ubiquinol – the form that fights excess free radicals and can help protect the body's cells from damage.
