Intravenous Vitamin C for Cancer Patients

How Intravenoous Vitamin C Fights Cancer




And why more and more oncologists are now using it

by Andrew W. Saul

The success of intravenous vitamin C for cancer patients is a repeatedly-demonstrated clinical reality. Here is the full, detailed Riordan IVC protocol, a free download for everyone. Do not let loved ones suffer unnecessarily from one-sided care directed exclusively by physicians educated in pharmaceutical-funded medical schools. Bring your oncologist up to speed. No more leeches; no more calomel. No more procrastination about utilizing nutritional therapy. Enough is enough! Drop this protocol on your doctor's desk and demand an IV of vitamin C now. If the doctor refuses, go over their head or sue them for denying treatment. Cancer cells are killed by vitamin C precisely because cancer cells are different. Inside a cancer cell, vitamin C, normally an antioxidant in a healthy cell, actually acts as a pro-oxidant and kills a cancer cell. Give enough C and you can kill malignant cells almost anywhere they may try to spread or try to hide.

Pancreatic cancer

Because pancreatic cancer is notoriously difficult to stop, administering vitamin C is all the more important. Here is a free download for a paper showing clinical success with very high-dose IV vitamin C against stage 4 pancreatic cancer. senior author, Jeanne A. Drisko, MD, is a diagnostic radiology specialist and professor at the University of Kansas, Division of Integrative Medicine.

Ovarian cancer

Ovarian cancer was successfully treated in two patients with very high dose vitamin C therapy.

The study was done in 2003 and still a whole lot of people have not heard about it. Once again, it's the research of Jeanne Drisko, MD, and colleagues.

Vitamin C does not "interfere" with chemo Antioxidants and other nutrients do not interfere with chemotherapy or radiation therapy and can increase survival. (Simone CB 2nd, Simone NL, Simone V, Simone CB. Atlern Ther Health Med. 2007;13:22–28. See also: Block K, Koch AC, Mead MN, Tothy PK, Newman RA, Gyllenhaal C. Impact of antioxidant supplementation on chemotherapeutic toxicity: a systematic review of the evidence from randomized controlled trials. Int J Cancer. 2008;123:1227–1239. doi: 10.1002/ijc.23754.

"At high concentrations, ascorbate does not interfere with chemotherapy or irradiation and may enhance efficacy in some situations . . . Meta-analyses of clinical studies involving cancer and vitamins also conclude that antioxidant supplementation does not interfere with the efficacy of chemotherapy."

No, vitamin C does not "interfere" with chemo. I'm going to hit at this again and again. Why? Because innocent patients are suffering needlessly, and that really ticks me off. One of the original urban legends about chemo interference was hatched by Sloan-Kettering back in 2008. Here's the real story.

Not only does vitamin C not interfere with chemo, the vitamin itself IS chemotherapy against cancer. Vitamin C given intravenously is selectively toxic to cancer cells. And while various oral forms are very helpful adjuncts, when fighting cancer, it has to be intravenous C to get the job done right.

Why a cancer patient receiving conventional treatment also needs vitamin C:

• Vitamin C reduces the side effects of chemo.

• Vitamin C reduces the side effects of radiation.

• Vitamin C reduces post-surgical inflammation and infection, and reduces healing time.

Yes, cancer patients can and should take antioxidants and other nutritional supplements while undergoing radiation therapy or chemotherapy. Vitamin C and other nutrients reduce side effects, and actually improve the results with both chemo and radiation.

Radiation oncologist Victor Marcial-Vega, MD, always administers high dose vitamin C therapy to his cancer patients. Dr. Marcial-Vega says, “Vitamin C increases the beneficial effects of radiation and chemotherapy and decreases the adverse effects. But this is not a subtle effect, is not 15-20%, it’s a dramatic effect. Once you start using IV vitamin C, the effect is so dramatic that it is difficult to go back to not using it." (En español:

Chemotherapy for cancer is actually effective . . . in just over 2% of the cases. Radiation on localized tumors fares far better. Either way, nutritional support reduces side effects of such harsh treatments. Face facts: you are going to get nowhere with an oncologist if you flatly reject what they have to offer. And most patients and their families, scared out of their wits by a cancer diagnosis, are going to listen to that oncologist and use conventional therapy. If you want the doctors to listen to you, be ready to compromise with them. Then have something to say and give them an earful.

"After breakfast, I visited Linus Pauling who was staying in the room next to mine. When I walked in he was busy with a hand calculator. I told him that on the basis of my fifty patients I had concluded that he and Dr. Cameron were right, that vitamin C in large doses did improve enormously the outcome of treatment for cancer." [Orthomolecular Treatment of Cancer, by Abram Hoffer, MD, PhD ]

Physicians have been successfully using vitamin C against cancer since the 1970s and 80s. Those telling you otherwise are misinformed. Twenty-two years ago it was confirmed and reconfirmed that high-dose IV vitamin C is effective against cancer. How long do patients have to wait for it to be accepted as an essential, standard therapy? In Japan, it already is, says NEWSWEEK:

For those wanting to know precisely how vitamin C fights cancer, here you go: Hunninghake, MD, is the presenter. The second half is more directly about intravenous vitamin C. Dr. Ron is medical director of the Riordan Clinic. He has decades of experience and has supervised tens of thousands of IV vitamin C treatments. As your own life progresses, observe how many critics of vitamin C are so certain of their negative beliefs that they will never view this video.

Vitamin IVs can be arranged in virtually any hospital, anywhere in the world . . . if you push hard enough. Learn how from an attorney - who also just happens to be a board-certified cardiologist. Free download of a presentation by Thomas E. Levy, MD, JD.

A final note concerning intravenous vitamin C: Do not accept stories that "the hospital can't" or "the doctor can't" or that "the state won't allow it." If you hear any of this malarkey, send me the text of the policy or the law that says so. In the meantime, here is how to take the reins and get the vitamin in the veins:

Book Offers Guidance on Nutrition and Supplements in Cancer Treatment

Townsend Letter, August-Sept, 2010. Reviewed by Jule Klotter

All too often, oncologists give cancer patients little guidance on ways to use nutrition and supplements to aid their recovery and prevent recurrence. The book I Have Cancer: What Should I Do? by Michael J. Gonzalez, DSc, PhD; Jorge R. Miranda-Massari, PharmD; and Andrew W. Saul, PhD, fills this gap. Gonzalez and Miranda-Massari are members of RECNAC II at the University of Puerto Rico. RECNAC II is a research initiative that was inspired by Dr. Hugh Riordan's RECNAC project at the Center for the Improvement of Human Functioning (Wichita, Kansas). Saul is assistant editor of the Journal of Orthomolecular Medicine and author of Fire Your Doctor! and Doctor Yourself.

I Have Cancer: What Should I Do? gives readers the basics about nutrition, supplements, and lifestyle that can be used with conventional cancer treatment. It explains the orthomolecular (high-dose supplement) program that the authors themselves would follow if diagnosed with cancer. It is also the program that Saul uses to prevent cancer. "Cancer is a multifactorial disease that requires a multifactorial treatment plan: medical, nutritional, and lifestyle changes as well as mental, emotional, social, and spiritual support," assert the authors. "You cannot just take some pills and not change your diet, or change the diet and ignore important emotional or spiritual issues in your life, and then expect that everything will be fine. Any effective approach for cancer must be truly integrated." Keeping that in mind, the authors explain why nutrition is such an important part of any treatment plan. Food choices can reduce toxic effects of oncology treatments, strengthen the immune response, and aid recovery. The dietary guidelines are the basics: a whole-food diet that includes pulses (beans and lentils), whole grains (particularly sprouted grains), nuts, and an abundance of fresh vegetables and fruits. The authors recommend limiting red meat and salt and avoiding sugar and dairy foods altogether, particularly if the cancer is hormone related. Fresh air, exercise, and drinking plenty of pure water are strongly encouraged. The book also discusses dietary supplements that reinforce and augment the benefits of this diet plan.

In his foreword for I Have Cancer: What Should I Do? the late Dr. Abram Hoffer wrote: "Oncologists have to learn not to destroy hope. It is essential that patients not be deprived of hope even with what appears to be terminal cases. I have seen too many of these so-called hopeless cases recover." He tells of a middle-aged woman with kidney cancer that had spread to her back and aorta. Conventional oncologists had no treatment for her, so she entered hospice care. She also consulted Hoffer about orthomolecular treatment. Two years later, hospice discharged her because she was too healthy to die. Six years after consulting Hoffer, the woman was "still well." "Should you be afraid that it might be too late for you," Saul writes, "remember this: some 98 percent of the atoms in your body are replaced every year. And every one of those atoms can only come from what you breathe, drink, and eat."

I Have Cancer: What Should I Do? is well worth the $18.95 cost. The book teaches people self-care and gives much-needed words of hope. It is published by Turner Publishing/Basic Health Publications.

A Review by Robert G. Smith, Ph.D.

Research Associate Professor, Perelman School of Medicine, Department of Neuroscience, University of Pennsylvania:

"One might think, if the methods for treating this disease are as successful as described therein, that everyone would have already heard about them and the face of medicine would be changed forever.  That is the promise and I imagine the likely outcome of this book.  If read and appreciated by the medical establishment, the book may very well provide a new and fresh outlook to a difficult medical specialty -- and save many lives.


Some doctors have advised that nutritional supplements should not be taken along with chemotherapy.  The book explains that this is incorrect. Many doctors, aware that cancer drugs are toxic, simply haven't read up on the benefits of optimizing the nutritional state. Bad nutrition does not fight cancer. Nutrients given at high enough doses can optimize the body's biochemistry to allow it to react to stress which helps during treatment. Proper nutrition can reduce the secondary effects of the oncology treatment, strengthen the patient's immune system to prevent disease and reinforce the patient's health and recovery, and with appropriate macro and micro quantities of nutrients, treat the disease directly.


In fact, high doses of vitamin C and other nutrients can specifically target cancer cells. The authors explain that vitamin C is selectively toxic to cancer cells. . . .The growth of cancer cells is thought to be regulated and targeted by vitamin C because they take up large amounts of vitamin C along with their huge need for glucose. The vitamin C is thought to act in the cancer cell paradoxically as a pro-oxidant, generating hydrogen peroxide which stops the cell from dividing. Thus vitamin C can specifically target cancer cells, and along with its function to enhance the immune system, regress tumors. The effect is robust and has been shown many times in the clinical treatment of cancer patients. The amounts of vitamin C needed for this effect are large, and may require intravenous application of buffered ascorbate to achieve the high blood levels necessary, along with high doses of vitamin C taken orally. A study done by the Mayo Clinic didn't find any effect of ascorbate on cancer -- but the book explains that the lack of the anti-cancer effect was likely because the Mayo study didn't use enough vitamin C, discontinued therapy too soon, and doses were oral only, not intravenous. Vitamin C at high doses is known to be a very effective treatment for many types of cancer -- and it is non-toxic.

Overall, I think the book is excellent.  It is chock full of helpful information, much of which will be new to many readers. The book is very well-written and easy to read, and it has an extremely positive tone -- most likely because orthomolecular therapy works -- and not only for cancer!


“I recommend I Have Cancer: What Should I Do? to all of my patients. It is the best guide I have found.” (Victor Marcial, M.D., Oncologist) [En español: Video de los comentarios Dr. Victor Marcial]

"The authors base their findings on published, peer-reviewed research as well as their own personal experience with this deadly disease. I would strongly recommend this book to anyone with an interest in nutrition and cancer treatment and prevention. (James A. Jackson, Ph.D.)


Others say:

“This is an important book: all three authors were colleagues of Hugh D. Riordan, MD, one of the very first physicians to give high-dose intravenous vitamin C to effectively fight cancer. The authors are remarkably cheerful for wounded healers. Each has experienced loss due to cancer; one of the authors lost his wife. You might say, well, if they are so smart, then how did THAT happen? But the authors are not preachy nor do they come across as know-it-alls. They recommend conventional cancer therapy along with natural adjunctive therapy. It is not a one-or-the-other ultimatum. Better nutrition means better quality of life, and almost always improved length of life. After all, when is the last time that poor nutrition cured anything? There is truly good news in this book. Vitamins taken along with chemo results in undiminished drug effect plus fewer side effects. Intravenous vitamin C is selectively toxic to cancer cells, and does not interfere with chemo. If you have been told differently, this is the book for you. The authors back up their statements with a large number of peer-reviewed scientific studies. You do not have to "believe" in vitamins or nutrition or alternative medicine. The proof is here, and it is good news for cancer patients and their families. This book is not the sure cure. But it is a big step towards ultimate cure of this dreaded disease that affects so many. Here is information you really need to read.”
