Most people know that vitamin C is a potent antioxidant that has the power to boost immune function, increase resistance to infection, and protect against a wide range of diseases. But there is an entirely different and largely unknown role of vitamin C, and that is its ability when administered in very high doses by intravenous (IV) infusions to kill cancer cells.
Vitamin C interacts with iron and other metals to create hydrogen peroxide. In high concentrations, hydrogen peroxide damages the DNA and mitochondria of cancer cells, shuts down their energy supply, and kills them outright. Best of all and unlike virtually all conventional chemotherapy drugs that destroy cancer cells it is selectively toxic. No matter how high the concentration, vitamin C does not harm healthy cells.
Why IV Administration Is Essential
The only way to get blood levels of vitamin C to the concentrations required to kill cancer cells is to administer it intravenously. The body tightly controls levels of this vitamin by limiting intestinal absorption. If you took 10 g (10,000 mg) of vitamin C by mouth at one time, you would only absorb around 500 mg and you’d get a serious case of diarrhea!
Intravenous administration, however, bypasses this control mechanism, and blood levels rise in a dose-dependent manner. For example, 10 g of IV vitamin C raises blood levels 25 times higher than the same dose taken orally, and this increases up to 70-fold as doses get larger.This is very helpful in individuals who need extra vitamin support or those who have cancer.
