Active Q

Ubiquinol is the reduced, active antioxidant form of Coenzyme Q10 (CoQ10). Produced naturally within the body, ubiquinol is CoQ10 that has been converted ("reduced") for use in the cellular energy production process. In addition to its critical role in energy production, it is a strong lipid-soluble antioxidant, protecting the body's cells from oxidative stress which can cause damage to proteins, lipids and DNA.
For individuals who cannot efficiently convert regular CoQ10 (ubiquinone) to ubiquinol, supplementing with Active CoQ10 (ubiquinol) will restore healthy levels in plasma and organs for more efficient energy production.
For young, healthy individuals, regular CoQ10, ubiquinone should usually be sufficient for supplementation needs. Healthy adults can easily produce CoQ10 and convert it into ubiquinol; thus, supplementing with regular CoQ10 likely will be adequate to optimize their ubiquinol and CoQ10 levels.

For individuals who are 50 years and above, ubiquinol is likely more beneficial since the body's ability to produce CoQ10 and convert it into ubiquinol is less efficient. Optimal ubiquinol levels are important for those who would like to support overall health. Because ubiquinol is pre-converted, it is ready for immediate use by the body, making it suitable for those unable to efficiently convert CoQ10 in the body.
