what about increase or reverse this aging process in a smarter manner ? Supplementing in the raw component can have adverse effect. It seems like supplementing with co Q10 or hyaluronic acic.. Im really not a big fan

Thanks Tom, but have you read the book? This is a tiny piece of a comprehensive program. The question in no way addresses a possibility of any alternative, or what you might refer to 'smarter' manner of reversing aging. I am asking a very specific question related to the purity of PC. Kurzweil and Grossman must have based their advice on some research. I am trying to get hold of that particular piece of research. Maybe someone knows Ray or Terry well enough so they could ask them?

It looks like Ray and Terry sell standard 35% phosphatidylcholine. The label says 420 mg phosphatidylcholine and 10 calories, and 10 calories would make it ~1200 mg total weight.

Thanks for the link krillin! Even though the weight of components on the label is not straightforward for me, I found this list of literature at the webpage you gave the link to (see below).

These may or may not explain the reason why more pure PH is advised, however.
I will also write to info@rayandterry.com and if they give me an answer, I'll post it here myself.
Feel free to answer if you find the explanation first.

Maybe a bit offtopic, but NTFactor[1] came to my mind when reading this. I have always thought that NTFactor is some mumbo-jumbo and I have been reluctant to try it.
This is a good review of the so called "Lipid replacement therapy" [2]

Thanks mitomutant. Ray Kurzweil and Terry Grossman actually give a list of chemical compounds that is quite similar to Lipid replacement therapy (LRT) you mentioned. Phosphatidylcholine (aka PC, or PtC) is just one component of the many suggested in the book, and one of several components that comprise the LRT therapy (in your links).
I am trying to use one source of supplement recommendations (the book TRANSCEND by Kurzweil and Grossman) at the moment to keep things simple. The simplicity also comes from the fact that the authors provide recommendations for one chemical compound at a time rather than giving a patented mixture (as is the case with LRT). Each chemical recommendation is supported by extensive research. However, sometimes the book contains somewhat ambiguous statements that lack specific references to proper research. That was the reason I started this topic.

Too bad I didn´t know about this book. Just bought the Kindle version.
Now that I think about it, protecting the mitochondrial membrane is actually a good line of defense for my condition. Maybe I have been too centered in reducing ROS and it´s time to explore this. Thanks.

I contacted customer support at the site of the book (info@rayandterry.com) a couple of times and finally got the answer. I asked them the initial question and also asked why the product they sell differs from what they recommend in the book. Here is their answer (shortened):
"We have looked into a higher concentration and are interested in finding a pure material, but have not yet located one that is both reasonable in cost and available for oral formulations.

3) How did Ray and Terry come up with that 50% purity level? (Please point me to a specific research paper.)"The reason R&T recommend such a high purity is because of the difficulty in absorbing PtC orally. There are no specific citations regarding this advice and specific number. ...You could email Terry directly, perhaps he could offer you a more in depth answer regarding the percentage. Also he may be able to refer you to a physician offering IV PtC. ..."
Clean lecithin (i.e. no trimethylamine (TMA) contamination) does not result in TMA in the urine, while free choline does. That implies that the choline in phosphatidyl choline is completely absorbed before it can get to the gut bacteria that make TMA.

Thanks krillin! That page looks like it's about to disappear (with graphs missing). So I attached it to this letter. This is the quote from the paper to which (I think) you are referring:

Annoying. My impression is hucksters Kurzweil/Grossman are once again just talking out of their bums. They are conflating choline with PC. PC is only 13% choline, so I think what they really mean is they want a relatively larger dose of choline than the pityful 195mg in a tablespoon of lecithin, which is only 23% PC, and to be able to sell such a product at premium like all their other overpriced, privately labeled supplements.
The solution to me seems to be just take choline bitartrate which is about 41% choline. Nature's Way sells a mislabeled elephant-sized 1300mg tablet which provides 500mg of choline. For $8 or so.
