Abstract
Introduction Intravenous high-dose vitamin C therapy is widely used in naturopathic and integrative oncology; however, a study reviewing its effects has never been performed in Singapore. This article serves to document administration of supportive vitamin C therapy for cancer patients in Singapore. METHODS: The clinical response of 9 cancer patients of differing stages to the regular administration of large doses (25-100 g/d) of intravenous vitamin C (IVC; ascorbic acid) is outlined. Tumor pathology and patient health were verified by doctors who do not practice vitamin C treatment. RESULTS: Cases suggesting survival beyond prognosis, improvement in quality of life, safe coadministration with and improved tolerance of conventional therapy, and deterioration in clinical condition following withdrawal of vitamin C therapy are documented clinically. Some patients experience the Jarisch-Herxheimer reaction-the release of endotoxin from microorganism death resulting in pimples, fever, and body odor-for a few hours after the therapy, but these are resolved quickly with no lasting effects. CONCLUSION: Randomized trials of IVC therapy are recommended because it has minimal side effects and has shown promising results.
