How High-Dose IV Vitamin C Works Against Cancer
High-dose IV Vitamin C therapy challenges cancer cells at a metabolic level, yet causes no damage to normal, healthy functioning cells. There are over 91,000 publications on PubMed documenting its effects on cancer.
Cancer cells are both flawed and primeval compared to healthy human cells. They lack many of the enzymes that normal cells possess in large amounts, and are unable to use oxygen to metabolize glucose into energy. This fundamental difference is what makes high-dose Vitamin C selectively dangerous to cancer cells.
The Hydrogen Peroxide Mechanism
One key enzyme found abundantly in healthy cells is catalase, which transforms oxygen and water into hydrogen peroxide. High doses of Vitamin C (ascorbic acid) stimulate hydrogen peroxide production both inside and outside cells. Healthy cells use what they need and convert the remainder back into oxygen and water — a normal, controlled process.
Cancer cells, however, have very small amounts of catalase. They cannot convert the hydrogen peroxide and are instead oxidized and killed. This means ascorbic acid is simultaneously beneficial to healthy cells and harmful to cancer cells.
"It is gratifying to have our research on vitamin C and cancer confirmed by scientists at the prestigious National Institutes of Health." — Neil H. Riordan, Ph.D.
Confirmed by the NIH, NCI & FDA
The National Institutes of Health, the National Cancer Institute, and the Food and Drug Administration have confirmed the research findings first conducted by Linus Pauling, Ph.D., Hugh Riordan, MD, and other scientists over the past several decades regarding the therapeutic utility of treating cancer with Vitamin C.
The NIH study confirmed two key hypotheses in vitro:
- Tumor cells are more susceptible to the effects of high-dose ascorbate-induced peroxidation products because of a relative catalase deficiency.
- Concentrations of ascorbate high enough to kill tumor cells can be achieved safely in humans.
What to Expect at An Oasis of Healing
IV Vitamin C therapy at An Oasis of Healing is physician-supervised, individually dosed based on your labs and health history, and integrated within a comprehensive metabolic approach to cancer care. Our multidisciplinary team works with each patient to design a protocol appropriate to their specific condition.
We are currently accepting new patients. Speak with one of our Patient Care Experts to learn whether IV Vitamin C therapy may be appropriate for you.

High dose Vitamin C IV therapy challenges cancer cells at a metabolic level.
High dose vitamin C IV therapy challenges cancer cells at a metabolic level, yet does no damage to normal functioning healthy cells. There are over ninety-one thousand publications on PubMed regarding the effect this has on cancer.
Cancer cells, unlike healthy human cells, are both flawed and primeval.
Cancer cells are lacking in many enzymes that normal healthy cells have in large amounts. Additionally, they are not able to use oxygen to metabolize glucose into energy production.
One example of a particular enzyme that transforms oxygen and water into hydrogen peroxide is catalase. Hydrogen peroxide production in and outside the cells results from high doses of vitamin C (ascorbic acid). Hydrogen peroxide is used by normal cells for specific metabolic needs and whatever is not needed is converted into oxygen and water.
Cancer cells have very small amounts of catalase, so they aren’t able to convert the hydrogen peroxide into water and oxygen and as a result, they are oxidized and killed off. This tells us that ascorbic acid or high dose vitamin C IV therapy is very good for healthy cells and very bad for the cancer cells.
The National Institute of Health (NIH), the National Cancer Institute (NCI) and the Food and Drug Administration (FDA) have finally confirmed the research findings that Linus Pauling, Ph.D., Hugh Riordan, MD and many other scientists and physicians over the past few decades have conducted regarding the therapeutic utility of treating cancer with vitamin C.
The NIH study confirms in vitro, the hypotheses described by Riordan et al in “Intravenous Ascorbate as a Chemotherapeutic and Biologic Response Modifying Agent”:
- Tumor cells are more susceptible to the effects of high-dose, ascorbate-induced peroxidation products because of a relative catalase deficiency.
- Concentrations of ascorbate high enough to kill tumor cells can be achieved in humans.
