Clinical evidence

Millions of patients take Coenzyme Q10 (CoQ10)1,2, but there may be a better alternative

  • Use of CoQ10 is growing: approximately 574,000 more adults used CoQ10 in 2012 than in 20071 
  • In 2012, over 3 million US adults reported using CoQ10 in the past 30 days2 
  • CoQ10 is in the top 5 most commonly used dietary supplements1 

Ubiquinol is better absorbed and more bioavailable than conventional CoQ103-5

  • Ubiquinol has been shown to be up to 70% more bioavailable than CoQ10 in older healthy adults and in cardiac patients3

Ubiquinol has been shown to be up to 70% more bioavailable than CoQ10

The process of converting CoQ10 to active Ubiquinol becomes less efficient as a person ages 

  • Both forms of CoQ10—CoQ10 (ubiquinone) and Ubiquinol—naturally exist in the blood 
  • The body must convert oxidized CoQ10 (ubiquinone) into active Ubiquinol before it can play a role in providing cellular energy and act as an antioxidant6-8 
  • However, a patient’s ability to convert oxidized CoQ10 to active Ubiquinol becomes less efficient as a person ages9,10

More than 90% of CoQ10 in the blood of a healthy individual is in the form of Ubiquinol11

But the ability to turn oxidized CoQ10 into Ubiquinol becomes compromised and less efficient as patients get older or when they have certain health conditions9,10

The level of CoQ10 is still at its peak in most organs (heart, liver, kidney) at age 20. However, these levels start to decline with age. By age 40, CoQ10 levels in some organs have decreased as much as 50%. 

CoQ10 Distribution in the Human Body

For your patients already taking CoQ10, consider recommending Ubiquinol, which is more bioavailable and better absorbed3
