Vitamin C Proves Toxic to Tumors

A recent study by researchers concluded that tumor-toxic levels of vitamin C could be achieved by administering the vitamin intravenously (IV).

Investigators at the U.S. National Institutes of Health (NIH, Bethesda, MD, USA) recently confirmed that vitamin C is selectively toxic to tumor cells. The study was published in the September 12, 2005, issue of the journal Proceedings of the [U.S.] National Academy of Sciences. "These findings give plausibility to iv ascorbic acid in cancer treatment..,” reported the authors in the article.

"It is gratifying to have our research on vitamin C and cancer confirmed by scientists at the prestigious National Institutes of Health,” stated Neil Riordan, Ph.D., from the Bio-Communications Research Institute (BCRI, Wichita, KS, USA). BCRI scientists were the first to describe the pharmacokinetics of high doses of vitamin C. Their study was published in the British Journal of Cancer in 2001.

Since 1990, BCRI has published 20 articles on the study of vitamin C and cancer, and funded the first clinical phase I trial of IV vitamin C in patients with advanced gastrointestinal cancer. Findings of that trial will be forthcoming.
