How we scored it
Reduced Coenzyme Q10; parent CoQ10 is a fermentation product; reduction adds only two hydrogen atoms, negligible non-natural mass.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Produced by microbial fermentation to make Coenzyme Q10, then chemically reduced to ubiquinol. No petrochemical route is used commercially.
In plain English
The active, antioxidant form of Coenzyme Q10, made by fermenting microbes and then converting the result chemically. Used in skincare for its antioxidant effect.
CosIng definition: Ubiquinones, reduced
