Vitamin C and Cancer: Is There A Use For Oral Vitamin C?

Hickey, S., Roberts, H.
Journal of Orthomolecular Medicine, Vol. 28, No. 1, 2013

Discussed in the article:

  • the role of vitamin C in the treatment of cancer, addressing the controversy and clinical research surrounding its use
  • the potential of ascorbate as a safe and effective anti-cancer agent, capable of killing cancer cells while leaving healthy cells unharmed
  • rationale for oral supplementation of vitamin C with cancer:
    • the concentration of vitamin C required to be cytotoxic to cancer cells over longer periods is much lower compared to shorter periods of administration
    • oral intakes of vitamin C, particularly with combined use of ascorbic acid and liposomal vitamin C, can easily achieve and maintain adequate levels for selective cytotoxicity
    • during illness, the body responds by absorbing increased amounts of vitamin C from the gut to match increased tissue requirements, a process known as Dynamic flow

This means they can destroy cancer cells, while simultaneously improving the health of the rest of the body.
