Dear OncoLink "Ask The Experts,"
Is vitamin C good to cure cancer or take during a lot of during treatment?
Karen Wagner MS, RD, LDN, Clinical dietitian specialist for the Abramson Cancer Center, responds:
Vitamin C use during and after cancer treatment is currently being researched in a number of ways. At this point Vitamin C does not appear to cure cancer. High dose intravenous vitamin C is under research at a number of cancer centers to determine if it is helpful during treatment, but at this time it is not a standard part of treatment. If you are interested in these trials, please visit the National Cancer Institute for open trials. Oral Vitamin C supplements are generally considered safe at doses up to about 1000 milligrams per day, although they can cause diarrhea, nausea, cramps and should be used with caution with people with a history of kidney stones. Furthermore starting Vitamin C supplements during radiation is NOT recommended based on possible interactions with radiation and high dose antioxidants (Including Vitamin C, E, A and selenium). Eating foods high in Vitamin C seems to be very safe and increasing food sources of Vitamin C is generally a healthy recommendation. Foods high in Vitamin C are red bell peppers, citrus fruits, and green leafy vegetables. Do speak with your doctor, dietitian and/ or pharmacist to make sure that these foods will not interfere with any other medications you are taking or worsen any symptoms that you are having.
