Welcome to the best informed forum on PD around. I honestly don't think many of us here take Ubiquinol; it is so expensive and the clinical trial results mixed at best. Many of us here tend to focus on anti-inflammatory actions of various herbals- please see the thread "What is your chosen therapy/alternative treatments"
for a really good glimpse at what we we do use and why.
Also, for anyone interested in taking supplements, I highly recommend a subscription to Consumer Lab; they provide research reviews and test/rate various brands for many herbal and nutritional supplements. I don't like to recommend brands in an open forum but if you want to PM me, I will share.
I will post this from Consumer Lab on CoQ 10:
CoQ 10 is fat soluble and may be better absorbed when taken in an oil-based soft gel form rather than in a dry form such as tablets and capsules.1,81 Dividing the total daily dosage up into two or more separate doses may produce higher blood levels.
A finely ground up ("nanoparticular") form of the supplement appears to be much better absorbed than standard CoQ 10 products.86
