Hi there sylviak,
[quote]I checked another source which negates what Mercola said. If it is light yellow in colour, it is COQ10.[/quote]
Well that is true but both Ubiquinol and Ubiquinone are both forms of COQ10, and maybe they should have been named COQ10-1 and COQ10-2 or something along those lines for clarity as the constant name usage of COQ10 then Ubiquinone or Ubiquinol then Enhanced or Normal then reduced or oxidized is nothing more than confusing to everyone (the experts and advertisers need a good kick where it hurts for this one).
To be honest, I don't know each individual manufacturers processing method, slight changes in colour or texture etc could be the way their product is manufactured, I highly doubt if two different manufactures processes are identical unless they share the same technology and patent/formula to make an exact copy, even then all it would take in this situation is an exposure to air to make a difference in the process and colour.
It looks like there are more experts out there that just as with statins tend to be experts on what someone else mentioned, because they are meant to be experts, we all believe their explanations until once again everything we read or see is in conflict to what we were told. This is NOT intended/meant for anyone here it IS intended for the experts who keep everything in a complete state of confusion by using several names for the same thing and not keeping up with new techniques etc.
I enjoyed reading the (*http://www.zmc-usa.com/docs/CoQ10_Facts_or_Fabrications.pdf) in your post, great find but as I mentioned with all the conflicting information from the experts (and possibly newer methods of processing since 2007), who do you rely on for an accurate up to date answer?
Thanks also for some great bits of information (loads really) in some of your other posts
All the best,
Allen
