Intravenous Therapy (IV Therapy Vitamin C) for Cancer

What is IV Therapy? Intravenous therapy or IV Therapy is the infusion of nutrient or medicine into the vein bypassing the stomach. In Naturopathic Medicine, IV therapy is commonly used in cancer treatments and also in many acute problems such as flu, severe infections, fatigue, ulcerative colitis and much more. 

Vitamin C for Cancer Therapy

 There are many studies that look at vitamin C and its effects on cancer in a tissue culture. The concentrations of vitamin C used against cancer in tissue culture is achievable only with intravenous therapy.

 One study in the Journal of the National Academy of Sciences in 2008 reported on an experiment that showed that such high intravenous levels could reduce tumor volumes by 41-53%. This requires an intravenous dose of 60-75 grams (65000 - 75000 mg) per IV. In addition, high doses of Vitamin C therapy also significantly reduces fatigue, nausea, pain, and appetite loss from the chemotherapy.

Intravenous therapy of high doses of vitamin C has an excellent safety record.
The risks, as with any intravenous procedure, include infection, clotting and loss of the vein, infiltration (leakage) of fluid into the tissues around the needle site, bruising, and occasionally pain in arm. These are very rare.

 General Information

Vitamin C intravenous therapy can be utilized in conjunction with some Chemotherapy treatment. There are studies that shows Vitamin C favourably enhances chemotherapy drugs effects.

 Lab Test :

There are a few lab test that needed to be done to determine patient’s eligibility to for the treatment :  serum G-6-PD, kidney function test (eGFR), serum electrolyte level.

 Things to do before each treatment :

  1. Drink lots of water before each IV Therapy session
  2. Eat your meal before having the treatment
  3. Do not lift heavy weights or do vigorous exercise after the treatment

 Duration : Each treatment varies between 1-3 hours in duration

 SAMPLE of IV Therapy Cancer Treatment Schedule

 Session 1           25 g Vitamin C 

 Session 2    50g  Vitamin C   twice per week


Cost ranges from $130-$160 (+HST) per treatment


Evidence for Vitamin C Intravenous Therapy for cancer support

 “…intravenous administration of the same dose produces plasma concentrations about 25-fold higher. Larger doses (50-100 g) given intravenously may result in plasma concentrations of about 14,000 micromol/L. At concentrations above 1000 micromol/L, vitamin C is toxic to some cancer cells but not to normal cells in vitro. We found 3 well-documented cases of advanced cancers, confirmed by histopathologic review,where patients had unexpectedly long survival times after receiving high-dose intravenous vitamin C therapy. We examined clinical details of each case in accordance with National Cancer Institute (NCI) Best Case Series guidelines. Tumour pathology was verified by pathologists at the NCI who were unaware of diagnosis or treatment. In light of recent clinical pharmacokinetic findings and in vitro evidence of anti-tumour mechanisms, these case reports indicate that the role of high-dose intravenous vitamin C therapy in cancer treatment should be reassessed.“

 “ The antioxidant perhaps most widely used in complementary oncology is vitamin C, particularly by intravenous injection. In light of the recent clinical pharmacokinetic findings, the in vitro evidence of anti-tumour mechanisms and some well-documented cases of advanced cancers the role of high-dose intravenous vitamin C therapy in cancer treatment should be reassessed. High dose intravenous vitamin C therapy may have benefits in patients with advanced cancers, and cancers with poor prognosis and limited therapeutic options, but further clinical studies regarding the safety and efficacy of this therapy are necessary, especially in Germany”

“Ascorbic acid is an essential nutrient commonly regarded as an antioxidant. In this study, we showed that ascorbate at pharmacologic concentrations was a prooxidant, generating hydrogen-peroxide-dependent cytotoxicity toward a variety of cancer cells in vitro without adversely affecting normal cells. To test this action in vivo, normal oral tight control was bypassed by parenteral ascorbate administration. Real-time microdialysis sampling in mice bearing glioblastoma xenografts showed that a single pharmacologic dose of ascorbate produced sustained ascorbate radical and hydrogen peroxide formation selectively within interstitial fluids of tumors but not in blood. Moreover, a regimen of daily pharmacologic ascorbate treatment significantly decreased growth rates of ovarian (P < 0.005), pancreatic (P < 0.05), and glioblastoma (P < 0.001) tumors established in mice. Similar pharmacologic concentrations were readily achieved in humans given ascorbate intravenously. These data suggest that ascorbate as a prodrug may have benefits in cancers with poor prognosis and limited therapeutic options.”

“To test the carcinostatic effects of ascorbic acid, we challenged the mice of seven experimental groups with 1.7 x 10(-4) mol high dose concentration ascorbic acid after intraperitoneal administrating them with sarcoma S-180 cells. The survival rate was increased by 20% in the group that received high dose concentration ascorbic acid, compared to the control. The highest survival rate was observed in the group in which 1.7 x 10(-4) mol ascorbic acid had been continuously injected before and after the induction of cancer cells, rather than just after the induction of cancer cells. The expression of three angiogenesis-related genes was inhibited by 0.3 times in bFGF, 7 times in VEGF and 4 times in MMP2 of the groups with higher survival rates. Biopsy Results, gene expression studies, and wound healing analysis in vivo and in vitro suggested that the carcinostatic effect induced by high dose concentration ascorbic acid occurred through inhibition of angiogenesis.”

IV therapy

IV Therapy Vitamin C with Myers Cocktail also helps to boost the immune system, muscle recovery, detoxification , anti-aging and restoring one's adrenal energy as well.

Each Vitamin C injection may includes Myers cocktail (which contains high doses of Magnesium, Selenium, Zinc, Bcomplex, B12, B6, Sodium bicarbonate and Folic acid. )

Additional anti-biotic solution can be added as well as Glutathione injection as well.
