Intravenous Vitamin C Chemotherapy for Cancer

Chemo Options 


60,000 mg of Intravenous Vitamin C as Chemotherapy

There are many good reasons to give large quantities of ascorbate (vitamin C) to a cancer patient.

1. Vitamin C strengthens the collagen “glue” that holds healthy cells together and retards the spread of an existing tumor.

2. Vitamin C strengthens the immune system.

3. Vitamin C provides a surprising level of pain relief.  

4. Vitamin C dramatically reduces the side effects of both radiation treatment and chemotherapy.

5. Vitamin C does not interfere with either chemo or radiation.

But there's more. Vitamin C has been shown to be preferentially toxic to tumor cells, similar to cytotoxic drug cancer chemotherapy. Laboratory and clinical studies indicate that, in high enough doses, one can maintain blood plasma concentrations of ascorbate high enough to selectively kill tumor cells. If you have not heard about this, it is probably because most of the best-publicized vitamin C and cancer studies simply have not utilized high enough doses. Hugh D. Riordan, M.D., and colleagues have treatment data which “demonstrate the ability to sustain plasma levels of ascorbic acid in humans above levels which are toxic to tumor cells in vitro and suggests the feasibility of using AA as a cytotoxic chemotherapeutic agent.”
