Fully described in the article here, high dose (60 grams or higher) intravenous vitamin C can be a valuable aid in the treatment of patients with cancer. Recent studies report that intravenous vitamin C can alleviate cancer and chemotherapy-related symptoms such as fatigue, insomnia, loss of appetite, nausea and pain resulting in physical, cognitive and emotional symptoms.
More interesting still, vitamin C or ascorbic acid administration along with certain chemotherapy drugs like 5-fluorouracil (5-FU or xeloda), doxorubicin, and others, have been shown to increase the effect of chemotherapy against cancer. Thus increasing cancer cell death while reducing chemotherapy side effects. The impact of vitamin C on reduced side effects of chemotherapy and conjunction increased survival is often noted by our patients and their oncologists.
