A note on Co-Q10, I talked to a Perque sales rep so the info could be bogus, but she said that an independant study done on Co-Q10 resellers showed that much of the Co-Q10 on the shelves is Co-Q8 and has no effect on human's. Apparently, Perque's Mito Gaurd Plus is the one of the most pure. It is also more $$ than anything else I've found. I take 900mg a day and notice a difference in rigidity if I don't take it for a while. The rumor is,,, Japan manufactures most of the worlds Co-Q10 and not much of it makes it out. Conspiracy theory, who knows, here is a more detailed article about it - http://www.nutrilearn.com/softgel/coqsol.html

Coenzyme Q10 manufactured by microbiological fermentation is 100% in the all-trans isomeric form, identical in structure of the coenzyme Q10 made by the human body. However, material made by microbiological fermentation has the potential to contain other homologues, sometimes referred to “related substances” such as CoQ7, CoQ8, and/or CoQ9. Subsequent purification steps generally greatly reduce or eliminate the presence of the other forms of coenzymes listed above.
