Coenzyme Q10's duration depends on its half-life, formulation (IR vs ER), and your individual metabolism. Your pharmacist can pull the exact half-life from the FDA label.
Does dose affect how long Coenzyme Q10 lasts?

If Coenzyme Q10 appears to wear off before your next dose, talk to your prescriber. Options include dose adjustment, schedule change, or switching to an extended-release form — never adjust your own schedule.
