cjbrooksjc,
I do not know why about powder vs. gel caps, but I can believe it. All I have ever seen in stores are the gel caps. The particular molecule may be more stable in that "lipid-like" environment.
I don't really know much about the "origin of pain." Your issues may be more muscle-oriented than mine, but the pain aspect of it all is still nerve-based in the end. Nerves chemically and electrically "report" the insult of the muscle -- but, of course, they also report insults to themselves too. It may be a combination of these two factors for a lot of us -- in differing ratios?
The comment about the repair times of mitochondria was from a post I read in a thread in "Healthboard.com" last night about cholesterol and statin damage. A guy asserted six months for mitochondria, but he may or may not have based that on much. I will be looking for info on that issue though. I know that nerve cells are much slower to divide than others, but that does not mean that they do not repair or that their mitochondria do not divide -- and it is impaired mitochondria that I suspect may be responsible for a lot of statin problems. A problem is that their own DNA is not well protected (and particularly in the absence of CoQ10) in these organelles and there could be replication errors passed along. Here are a few "factoids" for you: As we get older mitochondria tend to divide (i.e., multiply) less inside the cells, and generally become less efficient. Athletes have more mitochondria in their muscle cells -- as responding to the performance demand. Cells division is distinct from mitochondria division inside the cells.
BTW, at the Healthboard forum, it appears that everyone is still sold on the Cholesterol Myth, so a lot of what they discuss is fundamentally flawed. There is one guy there "NHone, Senior Veteran" who knows what is up, but he is a lone voice and often just ignored -- but he keeps on trying, I have to give him that! I thought about registering and helping him out. Maybe some other time. I spent an hour or so reading threads there for the first time. This will take you to one, if you are interested. I think this is the board that people here have reported getting kicked off of for speaking the truth. I gotta hunch some of the rest of us I would not last long there either...
