Vitamin C doesnt reduce effects of chemotherapy in cancer, says expertMarch 6th, 2009 - 3:21 pm ICT by ANI
Washington, Mar 6 (ANI): Challenging a recent study, an Arizona nutritionist has claimed that vitamin C does not reduce the effectiveness of chemotherapeutic drugs in cancer treatment.
A study published in Cancer Research concluded that vitamin C, given to mice or cultured cells treated with common anti-cancer drugs, reduces the anti-tumour effects of the chemotherapeutic agents.
Jack Challem, a personal nutrition coach and nutrition author from Tucson, Arizona, pointed out two main problems with the study.
The problems were: the oxidized form of vitamin C (dehydroascorbic acid) and not actual vitamin C (ascorbic acid) was used; and in the mouse experiments, the animals were given toxic doses of dehydroascorbic acid, a compound that is not used as a dietary supplement in humans.
“This study and the subsequent headlines [it generated] were a grievous disservice to physicians and patients with cancer,” said Challem.
He added: Considerable positive researchhas shown striking benefits from high-dose vitamin C (ascorbic acid) in cancer cells and animalsand in actual human beings.”
High-dose intravenous vitamin C is a common form of alternative and complementary therapy for patients receiving chemotherapeutic drugs, and is believed to help bring about tumour cell death.
It may also promote post-surgical healing by enhancing collagen formation, and increase tissue resistance to tumour spread.
“The ideal therapeutic approach would be to tailor individual treatment, including IV vitamin C, from a menu of options, suggested Challem.
Challem made his claims in the Medical Journal Watch column in the current issue of Alternative and Complementary Therapies, a journal published by Mary Ann Liebert, Inc. (ANI)
