Vitamin C is a nutrient found in food and dietary supplements. It is an antioxidant and also plays a key role in making collagen. High-dose Vitamin C therapy may be given by intravenous (IV) infusion (through a vein into the bloodstream) or orally (taken by mouth). When taken by intravenous infusion, vitamin C can reach much higher levels in the blood than when the same amount is taken by mouth.
High-dose vitamin C IV infusion has been studied as a treatment for patients with cancer since the 1970s. Laboratory studies have shown that high doses of vitamin C may slow the growth and spread of prostate, pancreatic, liver, colon, and other types of cancer cells.
VITAMIN C AND CANCER
As early as the 1970s, some researchers were suggesting that using high doses of intravenous vitamin C along with cancer drugs could improve treatment of cancer. Intravenous vitamin C can produce very high levels of vitamin C in the body. Researchers believe that these high vitamin C levels can be toxic to cancer cells without harming the healthy cells of the body.
Some researchers think that vitamin C injections can make chemotherapy work better or prevent some chemotherapy side effects. There is some research that suggests vitamin C injections might help reduce side effects and improve quality of life.
