Here is a reprint of the letter rejecting the study from the NIH: (CLICK on the 1998 study proposal and again on the 2002 study proposal) Hopefully the links will work for you.
NIH Refuses to Study Pauling/Rath TherapyThe Pauling therapy is simple. Take high doses of two nutrients that are required for life. Doing so can prevent and even cure many forms of cardiovascular and heart disease - in days or weeks. The question becomes how much should one take?
We, under the auspices of the Vitamin C Foundation, submitted two study proposals to the United States National Institutes of Health, (NIH) Office of Alternative Medicine. We were inexperienced in submitting such proposals, but the NIH was free to solicit its own studies. Either proposal would have fairly evaluated the Pauling therapy on heart disease.
These submissions (and subsequent rejections) are a matter of public record.
Probably the main reason that this important discovery has been ignored is economic:Think of more than half the hospitals in your region closing.
With medical science asleep at the switch, we have been promoting and closely monitoring the effect of Pauling's therapy on heart patients for almost twenty years. One thing has become crystal clear: The large doses recommended by Linus Pauling are key to success  . Neither nutrient has any known lethal toxic dose in animal or human studies.
The reports have been so amazing that we documented the protocol and success stories in a book Practicing Medicine Without A Licence.
This long-term experience, (initially with dying heart patients who gave up on orthodox medicine and were taking a myriad of heart medications), leaves little doubt that :Cardiovascular (Heart) disease at its root is a vitamin C deficiency. Science can not dispute this assertion because it has never been tested at Pauling's recommended dosages.
So why after all these years and so many reports of success does medical research still have its collective head in the sand? We can only think of one reason:
The method for reversing heart disease invented by Linus Pauling does not require a doctor.
