ビタミンC
Ultimately the negative findings of the Mayo Clinic studies ended general interest in vitamin C as a treatment for cancer. Despite this, Pauling continued to promote vitamin C for treating cancer and the common cold, working with The Institutes for the Achievement of Human Potential to use vitamin C in the treatment of brain-injured children. He later collaborated with the Canadian physician Abram Hoffer on a micronutrient regime, including high-dose vitamin C, as adjunctive cancer therapy. A 2009 review also noted differences between the studies, such as the Mayo clinic not using intravenous Vitamin C, and suggested further studies into the role of vitamin C when given intravenously. Results from most clinical trials suggest that modest vitamin C supplementation alone or with other nutrients offers no benefit in the prevention of cancer.
