Although it's not approved by the U.S. Food and Drug Administration as a treatment or preventative drug, several new studies show that taking CoQ10 supplements may help address several chronic health conditions, including atrial fibrillation (a-fib), nonalcoholic fatty liver disease (NAFLD), insulin resistance, heart failure, cancer and migraines, to name a few.

Ubiquinol — the reduced, electron-rich form of CoQ10 that your body produces naturally — plays an important role in the electron transport chain of your mitochondria, where it facilitates the conversion of energy substrates and oxygen into the biological energy (adenosine triphosphate or ATP) needed by your cells for life, repair and regeneration.
