In the 1970s, researchers proposed that high-dose ascorbic acid could help build a resistance to disease or infection. Today it is believed that the level of vitamin C that collects in the bloodstream is dependent upon the way it is taken.

Since the 1970s, high-dose vitamin C has been used to treat cancer patients. Scottish surgeon Ewan Cameron worked with Nobel Prize-winning chemist Linus Pauling to study the possible benefits of vitamin C therapy in clinical trials of cancer patients in the late 1970s and early 1980s.

Surveys of U.S. CAM conferences show that high-dose IV vitamin C is frequently given to patients as a treatment for fatigue and certain cancers.

Method: Intravenous (IV) Infusion

Fortunately, when taken by intravenous (IV) infusion, vitamin C can reach much higher levels in the blood than when it is taken by mouth. According to the National Cancer Institute, studies suggest that higher levels of vitamin C delivered via IV infusion may cause the death of cancer cells.

In fact, high-dose vitamin C has been researched as a cancer treatment since the 1970s, and frequently given to patients suffering from infections, fatigue, and cancers like breast cancer in recent years.
