Vitamin C and Cancer Treatment: Natural and Effective Cancer Therapy Proven By New Studies

For years, the alternative community has successfully utilized high dose vitamin C for cancer treatment. However, despite evidence, the debate regarding whether or not vitamin C is an effective cancer therapy continues to linger on in conventional oncology, limiting patients’ access to this beneficial treatment.

To clear up the confusion, we decided to examine the history behind vitamin C’s role in cancer care and what more recent studies have to say about the efficacy of this long-debated treatment.

Vitamin C in History

The debate revolving around the use of vitamin C in cancer therapy has been a hot topic since the late 1960’s. Biochemist and Nobel Prize winner Linus Pauling brought the innovative treatment onto the cancer scene after a successful personal experience with vitamin therapy and several clinical studies that would eventually pave the way for orthomolecular medicine.

As Pauling drew more attention to vitamin C in the public eye, researchers around the world began to perform their own experiments. In 1982, well-known medical research center The Mayo Clinic conducted a clinical trial to determine the validity of Pauling’s claims. However, the trials were overseen by Charles Moertel, a researcher infamous for his prejudice against alternative medicine.

Knowing that Pauling’s claims related to high-dose intravenous vitamin C, Moertel instead administered the study using only oral vitamin C. As an oral supplement, vitamin C can only be taken at a rate of about 1 gram per hour. As part of an intravenous infusion treatment, patients may receive doses measuring anywhere from 15 to 100 grams, depending on the individual.

This significant difference allowed Moertel to discredit Pauling’s original, valid findings altogether. The Mayo Clinic concluded that vitamin C was ineffective for cancer treatment, and thanks to the involvement of money and politics, the conventional world has rejected its benefits ever since.   

Author Ralph Moss criticized the medical industry for exactly these reasons in his investigative book, The Cancer Syndrome. As a response to the exposition, Pauling himself penned a letter to Moss, stating:

“The ways in which the American people have been betrayed by the cancer establishment, the medical profession, and the government are shocking. Everyone should know that the ‘war on cancer’ is largely a fraud, and that the National Cancer Institute [NCI] and the American Cancer Society [ACS] are derelict in their duties to the people who support them.”

Newer Research Proves Vitamin C Effective

More recently, studies continue to validate what Pauling originally set out to prove. Late last year, two clinical trials at the University of Iowa definitively concluded that intravenous vitamin C therapy increased patient survival by 70%.

The first of these studies found that vitamin C made cancer cells more sensitive when exposed to radiation. The second monitored control and test groups of patients receiving radiation and a standard chemo drug. Patients who also received IV vitamin C as part of their therapy program displayed significantly less radiation damage to their normal tissues, illustrating just how important it is for vitamin C to be available as a complementary treatment.

Meanwhile, additional studies in Salford, UK, have highlighted the powerful effect vitamin C has on cancer stem cells, the parent cells responsible for cancer’s replication and resistant properties. Not only did vitamin C successfully inhibit cancer stem cell formation, it was ten times more effective at disrupting the cells’ metabolic processes than competing pharmaceutical 2-DG.

These studies prove that vitamin C therapy reduces the negative impact of conventional therapies, increases overall survival rate, and prevents cancer stem cell production. Alternative and integrative practitioners have been long aware of the enormous benefits vitamin C carries for patients, both as a supportive agent and as a proactive treatment. Yet the conventional medicine establishment continues to reject the tangible evidence.

How Vitamin C Works

Even in low doses, vitamin C is known for its immune supporting properties. As an anti-oxidant, vitamin C stimulates the production of collagen in the body, improving cellular stability, cancer resistance, and overall quality of life. However, when taken as an oral supplement, vitamin C must travel through the body’s digestive system, where its properties are inevitably broken down into varying amounts.

With intravenous administration, vitamin C can avoid the body’s digestive filter and is delivered right to the source, allowing for more controlled concentration at amounts 100-500 times that of oral ingestion. In these higher doses, vitamin C acts as a pro-oxidant and produces hydrogen peroxide, a chemical compound known for its ability to break down tissue and DNA. Healthy cells are protected from this effect thanks to an enzyme they produce called catalase. Cancer cells, on the other hand, do not produce catalase and are in turn subject to oxidative damage and cell death. Patients still receive all the supportive benefits of vitamin C, plus these more direct and effective cancer-fighting qualities.

In the 2016 University of Iowa clinical trials, scientists found high-dose vitamin C to be safe and well-tolerated across test subject populations. For practitioners of integrative medicine, this result is a well-established fact stemming from decades of experience with the treatment. However, as with any therapy, there are some risk factors that prospective patients should consider. For example, high-dose vitamin C is not recommended for individuals with hemochromatosis, G-6-PD deficiency, or a tendency to develop kidney stones. Any use of high-dose vitamin C therapy should be determined by a medical professional, and is most effective when used as part of a comprehensive program.

At Hope4Cancer, we believe that anyone fighting disease should have access to this simple, affordable, and effective non-toxic therapy. High-dose vitamin C therapy is available at Hope4Cancer clinics as an integral part of our comprehensive healing program.

      1. Hello Amee.

        We have treated many patients with brain cancer. You will see it included here. Hope4Cancer contracted a statistical research team from Cuba to conduct an on-site, retrospective analysis of our patient data. Their study is currently on-going (expected completion year 2020), and the data presented is based on their report for the 2-year time period between 2015–2017. Here is a link to our survival rates:

  1. Hi . I was diagnosted with mouth cancer this year . Im taking intravenous Vit C ( 25.000mg ) twice a week . My MD was totally against it and i had to wait about six months till one Dr. Prescribed the Infusion . However, i’ve had a surgery after five biopsys which showed precancer . The doctor removed the cancer , but still i have a white patch exactly where i’ve had the cancer . Im confused , frightened and sad . Why there’s not enough Research about mouth cancer , which is one of the worst cancer around . I allready had breast cancer back in 2010, and now my mouth . I had a friend who passed of mouth cancer and they had dig and dig till he looked like a monster . Do YOU have Any recomandations ? I also drink in the Morning all kinds of Greens and try to alkalize my gut . Thank you for your time .

      We have treated many patients with ovarian cancer. “Here is a patient’s experience at Hope4Cancer Treatment Centers. Trina was diagnosed with Stage 4 ovarian cancer.

        1. Yes, we have a lot of experience with Multiple Myeloma. Here is David’s story, a patient of Hope4Cancer, he lived in the UK for awhile and now resides in New Zealand: Also, Christine Margo, another patient of Hope4Cancer, she was diagnosed with Multiple Myeloma: Christine Margo’s New Testimonial Video page is live on the site!

  2. My sister has mouth cancer which was diagnosed as cancer of the pallate. We have done all that we have seen on the internet and heard from survivors but it has gradually progressed to what I think is stage 4 now.
    We gave her high dose of vitamin C, btw 1000mg to 4000mg per day over 3 weeks. We did not see any significant change but her feet started to swell afterwards.
    What can we do really?

    Thank you.

    1. Hello Lilian.
