Vitamin C is of great importance as a micronutrient for a wide range of functions and tissues. Beyond its role as an essential antioxidant, Vitamin C in high does have proven to be effective in fighting infections. What is important is to recognize that Vitamin C in high doses switches its role from an antioxidative agent to an oxidative drug. The corresponding chemical reaction is based on the presence of metals. Cancer cells contain much more metals as healthy cells. This does not only comprise iron and copper, but also toxic heavy metals like mercury or nickel. Due to this fact, Vitamin C acts as a natural cytotoxic drug on the majority of cancers. In a significant portion of cases, Vitamin C is more effective than conventional chemo agents. Unlike conventional chemo therapy, Vitamin C exhibits its cytotoxic effect mainly on malignant cells.

To turn Vitamin C into an anti cancer drug, high concentrations in the blood stream have to be reached. As oral uptake it is strictly limited, intravenous administration is the only way to achieve therapeutic concentrations. Experience shows that Vitamin C provides the best results in highly aggressive and fast growing tumors.

The therapy is tolerated well in most of the cases, possible side effects are nausea and vomiting due to tumor necrosis.
