Question: does all coq10 contain ubiquinol?
Answer: At any given time in the body, the total "pool" of CoQ10 and Ubiquinol is 20% CoQ10 (full trolley) and 80% Ubiquinol (empty trolley). Most practitioners recommend CoQ10. We know more about CoQ10 supplements because CoQ10 was developed first, not because it is better.
