First of all this started asking about EDTA and I am personally grateful EDTA therapy exists. There is a group of EDTA physicians (who formed ACAM.ORG) and who have created many miracles using EDTA IV. (Improving eyesight, etc.)
In the beginning, when heart patients had intractable pain and there was nothing more that conventional medicine could do, cardiologist would advise their patients to "check the internet for an alternative" probably thinking they would find the EDTA chelation doctors.. Instead many found us on the Internet, and the rest, as they say is history.
The standard ACAM EDTA protocol includes vitamin C and magnesium in the IV. Early on many people who had tried EDTA IV turned to us when it didn't work. Usually the doctors was using only EDTA, not the full ACAM protocol. This happened enough to convince me that EDTA will not work like the Pauling Therapy - unless it contains part of the Pauling therapy, i.e. vitamin C (and magnesium). And as far as the EDTA pills, you would need a lot, maybe half a bottle, to be equivalent to the EDTA intravenous infusion.
So if you think that part of your problem is heavy metal toxicity, then you should consider adding EDTA, and I would recommend it IV. In Ty Bolinger's cancer book, he reports on a case of a mother curing her son's Autism - and the protocol relied heavily on "chelation." If I had a child with Autism, EDTA chelation would be high on my list of protocols to try.
Finally, thanks to Life Extension Foundation, we have learned that there is nothing better than vitamin K for moving calcium out of soft tissues and into bone! (Note this hormone like action preserves the calcium for bones, where as EDTA would move calcium out of the body through the urine.)
Finally, I too hope the vitamin C you have obtain is really vitamin C. Dr. Cobb and others who routinely prescribe the Pauling protocol to heart patients have noted that failures only occur on "other" forms of vitamin C. As Joanna45 has pointed out, she obtained great benefits in 4 days on pills. If someone has not experienced relief on the Pauling therapy, and are using an inexpensive vitamin C, try another brand and see what happens. And please report the results to us here at this forum. I, for one, would really like to understand why some forms of "vitamin C" do not work. (Are some brands not real vitamin C?) Now, our approved products are all ascorbic acid (as is most vitamin C on the market) so non-ascorbic acid vitamin C might be part of it. Looking for answers here.
