What Are Some Benefits of Vitamin C Injections?

Vitamin C injections seem to slow the growth of prostrate, pancreatic, liver and colon cancer cells in animal studies of high-dosage injections, notes the National Cancer Institute. Human studies of vitamin C injections reveal improved quality of life in patients, including reduced nausea, vomiting, pain and appetite loss in addition to increased physical, mental and emotional functions.

Vitamin C injections have also been proven to kill viruses and help treat chronic fatigue syndrome and fibromyalgia, according to the Center for Health and Healing. Although the U.S. Food and Drug Administration has approved high-dosage vitamin C injections as a dietary supplement, it has not approved these injections as treatment for cancer and other medical conditions. It may take time before vitamin C injections become widespread, reports BBC News, because pharmaceutical companies are hesitant to run large-scale government clinical trials of the treatment given that vitamin C cannot be patented.

Vitamin C injections may also be harmful to patients with a history of kidney disorders, notes the National Cancer Institute. These patients may experience kidney stones and kidney failure as a result of the injections. The injections are also not recommended for patients with hemochromatosis, a disorder that stores excessive iron, because vitamin C makes iron more easily absorbed and stored by the body.
