The dosage varied somewhat ranging from 10-30 grams daily and was continued indefinitely. The concentrations associated with this effect can only be achieved in living animals with intravenous injection of high doses of Vitamin C so some have argued that the studies showing no benefit from oral use should be re-evaluated with intravenous dosing. Oral administration of the maximum tolerated dose of vitamin C 18 gd produces low plasma concentrations due to limited absorptive capacity through the gut whereas intravenous administration of the same dose produces plasma concentrations about 25-fold higher.
While it is at lower doses the anti-cancer effects at the needed super-doses are actually pro-oxidant. Only intravenous administration of vitamin C can deliver the high doses found to be effective against cancer. Vitamin C at higher doses and when given in sufficient amounts intravenously will cause remarkable changes.
IV vitamin C when administered by a trained experienced physician is safe and well-tolerated even at doses as high as 100000 mg 100 grams per day. Intravenous administration however bypasses this control mechanism and blood levels rise in a dose-dependent manner. Intravenous Vitamin C is the only method proven to do this oral Vitamin C has not yet proven to be a successful treatment for cancer Also we know that intravenous use of high-dose Vitamin C has little chance for toxicity.
Vitamin C may have some side effects. In many alternative human practices vitamin C is being used in doses ranging from ten to 100 grams often twice weekly given as a fluid infusion to the patient over a period of a couple of hours. For more on these concepts click here The way to create the doses needed vaguely 1000 micromolL in the blood is by giving IV injections of the vitamin.
At sufficient amounts unlike typical cancer treatments Vitamin C given intravenously will raise the level of hydrogen peroxide in the bloodstream and kills cancer cells leaving normal cells alone. The company that makes the dietary supplements is responsible for making sure they are safe and that the claims on the label are true and do not mislead the consumer.
