Bioavailability of Ubiquinol in Huntington Disease
Bioavailability of Ubiquinol in Huntington Disease

The death of brain cells in Huntington Disease (HD) is thought to be associated with a lack of normal cell energy and harmful brain substances called free radicals. Coenzyme Q10 (CoQ) is a marketed nutritional supplement that may prove useful in HD because it increases cell energy and combats free radicals.

Most studies of CoQ have looked at only one formulation of CoQ ("ubiquinone") in HD. The purpose of the study is to find out if people that switch from the common formulation of CoQ ("ubiquinone") to a different formulation ("ubiquinol") have higher levels of CoQ in their blood after taking the same dose. The investigators also want to find out if this different formulation is tolerable for individuals with HD.
