Intravenous Therapies

Intravenous Therapies

Linus Pauling

There are multiple routes (oral, intramuscular, subcutaneous are all examples) through which medications and nutrients can be taken into the body, and intravenous is the most direct and immediate route. We provide a number of intravenous therapies developed through the practice of Orthomolecular Medicine. In the 1960’s, biochemist Linus Pauling coined the term “Orthomolecular Medicine” in reference to the practice of applying megadoses of vitamins, minerals, electrolytes, and other nutrients essential to the function of the body with an aim at “correcting” imbalances or deficiencies which could be contributing to an illness or disease. Orthomolecular medicine is not necessarily meant to replace or be used instead of conventional practices such as pharmaceutical medications and surgical interventions. Rather, it is a safe means of supporting the functionality of the body with the intent of recovery from an illness or disease.

Intravenous High Dose Vitamin C (IVC) 


The practice of administering high doses intravenously of sodium ascorbate (a mineral salt of ascorbic acid) in a clinical setting for people diagnosed with cancer was discussed by Linus Pauling and Ewen Cameron in several seminal publications:

  1. Cameron, Ewan, and Linus Pauling. “Supplemental ascorbate in the supportive treatment of cancer: Prolongation of survival times in terminal human cancer.” Proceedings of the National Academy of Sciences 73.10 (1976): 3685-3689. (See article here)
  2. Cameron, Ewan, and Linus Pauling. “Supplemental ascorbate in the supportive treatment of cancer: reevaluation of prolongation of survival times in terminal human cancer.” Proceedings of the National Academy of Sciences 75.9 (1978): 4538-4542. (See article here)
  3. Cameron, Ewan, Linus Pauling, and Brian Leibovitz. “Ascorbic acid and cancer: a review.” Cancer Research 39.3 (1979): 663-681. (See article here)

These publications were then refuted in a 1979 publication by Creagan et. al. (4) however, the vitamin C in the Creagan study (10 grams) was administered orally, which differed significantly from the methods of Pauling and Cameron who administered a combination of intravenous and oral ascorbate.

Case Studies and In Vitro Studies

Over the ensuing decades, much, much more investigational research has been done on the application of intravenous Vitamin C in cancer care. While a select few case studies (5, 6, 7) have demonstrated possible tumor-reducing, chemotherapeutic properties, unfortunately such results are not reliably obtained. In vitro (lab) studies likewise conclude that Vitamin C has the potential to induce cell death in cancer cells (8, 9). However, other than in a limited number of case studies, Vitamin C does not reliably shrink or resolve malignant tumors. With further research and innovation, however, the use of intravenous Vitamin C as a nontoxic cancer treatment might one day be a reality.

Improving Quality of Life and Outcomes During and After Cancer Treatment

While not reliably chemotherapeutic in its actions, Intravenous High Dose Vitamin C (IVC) has been shown in both case studies and clinical studies to significantly improve quality of life – as well as outcomes – in patients undergoing conventional cancer therapy for breast, prostate, ovarian, pancreatic and various other cancers. Moreover, it has done so safely and without toxicity. Specific benefits include:

  • Improvement in Quality of Life as related to physical, cognitive, and emotional measures (9, 10, 11, 12)
  • Improvement in nausea/vomiting, appetite loss, fatigue, and pain (9)
  • Decrease in inflammation which plays a role in cancer development, growth, spread, and treatment resistance (13)
  • Inhibition of cancer stem cell (CSC) recruitment (14)

Renal impairment and a deficiency in glucose-6-phosphate dehydrogenase are the only two known risk factors for withholding intravenous high dose Vitamin C. G6PD levels should always be checked via blood before administering intravenous high dose Vitamin C, as death could result in a person with deficient levels due to a rare genetic condition. In a survey of physicians who administered IVC to 11,233 patients in 2006 and 8,876 patients in 2008, researchers reported that the most common indications for administration of IVC were infection, cancer, and fatigue. The researchers also reported that,”Of 9,328 patients for whom data is available, 101 had side effects, mostly minor, including lethargy/fatigue in 59 patients, change in mental status in 21 patients and vein irritation/phlebitis in 6 patients” concluding that “high dose intravenous Vitamin C appears to be remarkably safe” (10).
