The Instability of Ubiquinol, Part 2 – Dog Studies

William Judy Ubiquinol , , , , , , , 0 Comment

The results from large dog studies done by SIBR Research show that orally administered ubiquinol is mostly converted to the ubiquinone form of Coenzyme Q10 by the time it reaches the small intestines [Judy 2021 Part 2].

Coenzyme Q10 is an essential bio-nutrient, especially important as we get older. It is a redox molecule with an oxidized state called ubiquinone and a reduced state called ubiquinol. Both are bio-active states. Ubiquinone supplements are more stable and much more tested than ubiquinol supplements. Ubiquinol by nature of being an electron donor is relatively quick to be oxidized to ubiquinone.

In the small intestines, it is then absorbed primarily as ubiquinone. Once it enters the lymph, it is increasingly converted back to ubiquinol.

By the time it leaves the lymph to enter the blood circulation, it is approximately 96 % ubiquinol again.

These findings beg the question: why buy a ubiquinol supplement when the ubiquinol will probably be converted to the ubiquinone form of Coenzyme Q10 prior to absorption?
