title: Effects of High Doses of Vitamin C on Cancer Patients in Singapore: Nine Cases.
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.
  
  
  
  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.
  
  
  
  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.
  
  
  
  Randomized trials of IVC therapy are recommended because it has minimal side effects and has shown promising results.
