CoQH is an available form of the powerful antioxidant CoQ10. This form offers you the same broad-ranging benefits, but with heightened absorption which yields higher concentrations of CoQ10 in the blood. Ubiquinol has beens shown to provide powerful antioxidant defense and also supports the body's cardiovascular and energy systems by aiding in the synthesis of mitochondrial ATP. The comprehensive benefits of ubiquinol also aid the liver, brain and immune systems.
Just make sure you buy a good quality product.
Just to thank you for taking the trouble to post information, I did not know anyone taking CoQH or CoQ10 & wondering whether to continue.
