Neither oral nor intravenous Vitamin C improve cancer treatment

February 10, 2015

Dr. Mark Clemons recently published a comprehensive review of existing studies to determine whether there is scientifically compelling evidence to support the use of Vitamin C in cancer treatment, either to enhance chemotherapy or reduce its toxicity. The answer is no. Dr. Clemons' team systematically reviewed 34 articles for studies that involved more than 8,000 patients, finding no statistical difference between those who took Vitamin C and those who did not. The paper published in The Oncologist has also been selected for Continuing Medical Education accreditation, an indicator of its medical education impact.
