Not all forms of CoQ10 are equal. The form you choose determines how much CoQ10 actually reaches your tissues, and the difference between the best and worst forms can be substantial. FormulaForge’s formulary ranks each form by bioavailability tier (S1–S4) and formulary tier (T1–T4), giving you a research-backed guide for choosing wisely.

The Science

The following studies and findings inform FormulaForge classifications for CoQ10:

Elderly human crossover RCT: standard ubiquinone capsules were the lower-bioavailability reference arm, with a water-soluble CoQ10 formulation showing roughly 2.4-fold higher absorption. PMID: 32188111
Human bioavailability study: conventional ubiquinone formulations were outperformed by a novel colloidal delivery system, with plain ubiquinone as the lower-bioavailability reference. PMID: 19284181
Human study: a solubilized CoQ10 formulation showed roughly 3-fold higher relative bioavailability than standard ubiquinone powder and softgel preparations, which served as the 100% reference. PMID: 9565826
