The reference to Coenzyme Q10 is from an Italian study done some time back. I came across the reference myself when I was diagnosed with Stage I in 2011, and to tell you the truth, although my “credulity factor” is not high, I have been taking 250mg of CoQ10 daily since that time. The study’s results were compelling, but as far as I can see, no new study has been undertaken – Coenzyme Q10 being in the public domain and all. No profit motive for corporate backing.
The sample size of the study was small – that was its major flaw. However, CoQ10 is considered low on side-effects, so it seemed like a little insurance. It’s just my personal choice – I understand why it can’t be officially recommended without further, much more robust investigation.
I’ve found a reference on this forum, if it will let me post a link…
