High Dose Intravenous Vitamin C

High Dose Intravenous Vitamin C


Mega dose Intravenous Vitamin C 
25,000 mg (25grms) to 100,000mg  (100grms).
Vitamin C, (plant based), when given intravenously acts differently than when given orally.

It acts as an oxidative agent. It produces Hydrogen Peroxide which selectively destoys cancer cells and viruses. Normal cells produce an enzyme catalase which protects against peroxide.  Cancer cells fail to produce this enzyme.

It may be given in conjunction with chemotherapeutic agents.

"The benefits of Vitamin C, especially in higher doses, for treating a wide range of health problems, has been recognised and studied since the 1930's

Many great Scientists, Doctors, and  researchers have published studies on it and most are now available online."

The Riordan IVC Protocol

Presenter: Ron Hunninghake, M.D. - Riordan Clinic's own Dr. Ron Hunninghake served as the keynote speaker for this symposium. 

Many Ways Vitamin C Affects Cancer & Health

Dr. Riordan presents the latest research data regarding the effectiveness of vitamin C as a therapy for people with cancer and how it works in three ways.

US based, Dr. Riordan shares what he has learned in 29 years of administering high dose vitamin C to people with cancer and viral ailments. Learn the latest in how nutrients affect gene expression.

Benefits and Advantages of Intravenous (IV) Vitamin C Therapy

Nutrients are delivered directly to the cells through the bloodstream.


With intravenous Vitamin C therapy, as soon as your drip starts, Vitamin C is quickly circulated through your bloodstream and delivered to cells, where it is immediately available for use. 


The very process of having Intravenous Vitamin C, allows it to bypass the digestive and gastric systems, where sometimes there may be issues of poor digestion or absorbtion, so the vital mineral (vitamin) is immediately put to use by the body, without any losses due to the digestive process.


This also means no upset stomach or intestinal problems like cramps, nausea, or diarrhea, which sometimes result from taking high doses of oral Vitamin C.


IV Therapy facilitates the higher doses necessary for effective treatment outcomes.


Research has shown that there are specific blood or tissue concentrations of Vitamin C

that must be achieved in order for them to be pharmacologically active. Numerous studies show high concentrations of Vitamin C are required in the serum and intracellular fluid before it can exert its beneficial effects.


These high concentrations simply cannot be achieved by taking the nutrients orally; the 

bulk of vitamins and minerals swallowed in pill or liquid form is excreted, with very 

little actually absorbed into the bloodstream. Complicating this further is that many 

patients may have conditions that impair their intestinal absorption in the first place. 


Finally, as noted above, many patients cannot tolerate high doses orally of certain vitamins and 

minerals because these upset their stomachs. Therefore, only intravenous vitamin therapy 

can directly deliver pharmacologically effective doses of the required nutrients.

Quality of Life benefits

Dr Stewarts Clinic use IV Vitamin C to treat several different health conditions, 

and it is well documented to be also helpful to patients who are also undergoing regular cancer treatments.

"Extensive literature demonstrates that cancer patients experience vitamin C deficiency correlated with reduced oral intake, inflammation, infection, disease processes, and treatments such as radiation, chemotherapy, and surgery. 

Studies report reductions in inflammatory markers and suggest some improvement in symptoms, with a possible benefit in quality of life (QOL) when IV C alone or in combination with oral vitamin C is used in oncologic care."

There is a lot of information about IV Vitamin C online, so we would recommend to patients that are planning to visit us, and wish to learn more, to simply search online, using the term "IV Vitamin C ".

Several recent studies have indicated that intravenous (IV) vitamin C alleviates a number of cancer- and chemotherapy-related symptoms, such as fatigue, insomnia, loss of appetite, nausea, and pain. Improvements in physical, role, cognitive, emotional, and social functioning, as well as an improvement in overall health, were also observed.

Complementary treatment of breast cancer patients with i.v. vitamin C was shown to be a well tolerated optimization of standard tumour-destructive therapies, reducing quality of life-related side-effects.
