High Dose (IV) Vitamin C for Cancer

Vitamin C is by far one of the safest and most effective nutrients available to treat numerous health conditions. Doing Vitamin C therapy in IV form should not be confused with taking vitamin C pills orally which does not produce the same effect.
High dose Vitamin C levels that are toxic to cancer cells can be achieved in humans only with intravenous, not oral administration of vitamin C. 

Vitamin C is an antioxidant that neutralizes free radicals in the body and stimulates the immune system. When delivered in IV format, vitamin C acts as a pro-oxidant. Once inside the bloodstream, it operates as a helping agent that protects cells from damage caused by free radicals.

When vitamin C is absorbed inside cancer cells, it produces hydrogen peroxide that can cause oxidative damage and cell death to the toxic cancer cells – all without damaging any healthy cells.

Anton Kuraia is one of the thousands of people around the world who have seen incredible results after using this protocol. Watch his story below:

Vitamin C and Conventional Therapy

Patients getting vitamin C IV

When taken as a support protocol in conjunction with conventional treatments like chemotherapy and radiation, recent studies show that IV vitamin C alleviates a number of cancer and chemotherapy-related symptoms, such as fatigue, insomnia, loss of appetite, nausea, and pain.
Improvements in physical, cognitive, emotional, and social functioning, as well as an improvement in overall health, were also observed.

How Does High Dose Vitamin C Work?

Infusions can be given daily or several times a week, preferably over the course of several months. The exact dosage varies based on the individual, their diagnosis, and what other protocols they are undergoing, but an average dose usually falls between 50,000mg and 100,000mg. 

It is important that each intravenous treatment is tailored to the individual patient and particular situation.


IV Vitamin C Side Effects 

Overall, only minor side-effects have been noted in the administration of IV vitamin C, some of which are lethargy/fatigue, change in mental status, and vein irritation. These tend to be rare, and clinically, if they do occur they are temporary and easily corrected.

The History of High Dosage Vitamin C Therapy


Vitamin C was first suggested as a tool for cancer treatment in the 1950′s. In 1976 an article co-authored by Linus Pauling showed that 100 terminal cancer patients treated with intravenous vitamin C lived four times longer than a control group of 1,000 patients who did not receive vitamin C.

Pauling was a twice Nobel Prize–winning chemist who was one of the early champions of the idea that vitamin C could combat a host of illnesses, including cancer.

What Other Diseases Can be Treated with IV Vitamin C?

High dosage IV vitamin C has been used to treat cancer, cardiovascular disease, Age-related macular degeneration (AMD), cataracts and more. 

Vitamin C For Cancer- Clinical Research

One study done in the early 2000s compared cancer patients who took vitamin C orally versus those who received it intravenously and found that the patients who received the IV produced much higher plasma and urine concentrations with potential antitumor activity. 

In 2022, a series of pre-clinical and clinical trials using IV Vitamin C led researchers to conclude that “a large body of evidence is accumulating suggesting that Vitamin C when administered intravenously and in high doses, has potent cancer-selective cytotoxic, cancer-therapy sensitizing and toxicity-reducing properties.”

Thanks in no small part to all of the potential discovered in these studies, The Mayo Clinic has announced they are now conducting a randomized double-blind Phase 2 clinical trial to study the benefits of using high-dose IVC in combination with chemotherapy. Results are expected to be published in March 2024.

  • Before the polio vaccine, vitamin C was used as a high dose intramuscular injection every 8 hours in the treatment of polio with some success.
  • New clinical trials are currently underway to investigate the effect of intravenous vitamin C in the fight against COVID-19 infected pneumonia. Doctors in Shanghai are already utilizing IV vitamin C as part of the treatment for Covid-19 patients.

Vitamin C IV- Relevant Research and News

Vitamin C Reduce Risk of Breast Cancer Mortality

Vitamin C and survival among women with breast cancer has been studied numerously. In this study, the researchers performed a meta-analysis of 10 studies that were done over the years. A total of 17,696 breast cancer cases were examined, and the results suggest that post-diagnosis vitamin C supplement use may be associated with a reduced risk of mortality. Dietary vitamin C intake was also statistically significantly associated with a reduced risk of total mortality and breast cancer-specific mortality.

Benefits of High-dose Vitamin C on Breast Cancer Cells

a 2019 published article concludes – Combining highdose vitamin C with conventional anti-cancer drugs can have therapeutic advantages against breast cancer cells.

Highdose vitamin C (≥10 mM) significantly decreased cell viability of all breast cancer cell lines, particularly of MCF-7 cells. The catalase activities of MCF7 and MDA-MD-231 cells were also lower than those of MCF10A cells. Moreover, cell viability of both MCF7 and MDA-MD-231 cells was decreased further when combining highdose vitamin C and eribulin mesylate, and this was also true for MCF-7 cells when combining highdose vitamin C with tamoxifen or fulvestrant and for SK-BR3 cells when combining highdose vitamin C with trastuzumab in comparison with chemotherapy or endocrine therapy alone.
