Vitamine C tegen kanker.*

Uit een laboratoriumonderzoek blijkt dat een hoge dosis vitamine C, ingespoten in de bloedbaan kankercellen met 50% doet slinken, terwijl gezonde cellen onaangetast bleven. De dosis (10 gram) is zo hoog en te hoog om in tabletvorm ingenomen te kunnen worden. Enkele recente onderzoeken gaven al aan dat vitamine C in tabletvorm geen effect had op kankercellen. Het probleem met pillen en tabletten is dat na inname de opname in het bloed boven een bepaald verzadigingspunt niet meer plaatsvindt. Bij injecteren heb je hier geen last van zodat veel hogere dosis mogelijk zijn.

In de praktijk is het zo dat eenzelfde hoeveelheid geïnjecteerd of door de mond een verschil geeft van liefst 2500% in opname!

High intravenous vitamin C dose fights cancer

be taken orally, hence the intravenous administration. Some recent trials showed orally administered vitamin C had no effect on cancer cells, so the researchers decided to see what would happen if they injected the ascorbate straight into the bloodstream.
Earlier work in the 1970s which used both intravenous and oral ascorbate had hinted at an anti-cancer effect.

In the latest study a US team led by Dr Mark Levine, from the National Institutes of Health in Bethesda, Maryland, conducted laboratory experiments which simulated clinical infusions of vitamin C.

Cultures of a range of nine cancer and four normal cell types were studied by exposing them to high doses of ascorbate.
They found that while the normal cells were not affected, 5 of the cancer cells became 50% smaller. The lymphoma cells were completely destroyed.
The problem with oral administration is that you eventually come to a high dose (saturation point), any dose above that amount does not result in more ascorbate present in the bloodstream. Intravenous administration allows the patient to have even higher quantities in his/her bloodstream.
If you inject 10 grams of vitamin C straight into the bloodstream, you get concentrations 2500% higher than you would ever get by swallowing the same amount.
The study was led by Dr. Mark Levine, National Institute of Diabetes and Digestive & Kidney Diseases. You can read about this study in detail in the Proceedings of the National Academy of Sciences.
When asked why the cancer cells were dying, the researchers suggested it may have been due to the formation of hydrogen peroxide. Hydrogen peroxide kills cancer cells. However, they said they were not sure.
The researchers say further tests are needed to validate these findings.( Sept. 2005)
