DrWhitaker.com states, “… 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’s 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. … 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.”
Dr. Whitaker continues:
“The only way to get blood levels of vitamin C to the concentrations required to kill cancer cells is to administer it intravenously. … 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.”
