Bioavailability

The oral bioavailability of ubiquinol recently has been reported to be greater than that of Ubiquinone in healthy adults. The oxidized form ubiquinone10 was ineffective in ALS patients and modestly effective in mouse models of ALS.

Dosage Studied

Sixty-six patients were given either ubiquinol or ubiquinone orally at a dosage of 100 mg/day, or a placebo for 1 month. Salivary secretion and salivary CoQ10 content were analyzed before and after treatment. No clinically relevant changes in results of standard laboratory tests, physical examination, vital signs, or ECG induced by ubiquinor were observed in any dosage groups.

" The levels of CoQ10 in the brain and spinal cord of ubiquinone10- or ubiquinol10-treated mice were only slightly higher (≤10%) than the endogenous levels in vehicle-treated mice, indicating poor CNS availability after oral dosing and possibly explaining the lack of pharmacological effects."( A mouse model of familial ALS has increased CNS levels of endogenous ubiquinol9/10 and does not benefit from exogenous administration of ubiquinol10.
