|Vitamin C: It’s all in the delivery|
Borrowers who practice responsible
For the past three decades, scientists have reported conflicting results when investigating vitamin C’s cancer-fighting ability. Now, researchers from the National Institutes of Health say it’s the amount of vitamin C and the manner in which it’s delivered that makes all the difference. Their findings, reported in the Proceedings of the National Academy of Sciences, show that taking vitamin C by mouth doesn’t kill cancer cells but using intravenous ascorbate (vitamin C) therapy does, since it delivers doses high enough to produce hydrogen peroxide, which kills cancer cells while leaving normal cells unharmed. So far though, tests have been performed only on cells in the laboratory, and more research needs to be done to determine vitamin C injections’ effectiveness on humans.
