Naturopathic Doctors undergo extensive training, gain specialized experience, and achieve additional, comprehensive, certifications to practice IV therapy. This form of therapy can provide essential nutrients to enhance the quality of life and reduce side effects for those undergoing conventional cancer treatments. IV therapy alone has shown to extend therapeutic benefits through multiple physiological pathways, improving overall health and outcomes within cancer care. Beyond cancer, IV therapy has also been documented to support and improve various common health concerns and conditions.

IV therapy achieves blood levels of essential nutrients that are otherwise unobtainable through oral dosing, with a higher absorption. At these higher doses, the nutrients can exert different pharmacological effects compared to oral alternatives, such as anti-cancer effects, immunological support, and anti-fatigue benefits. By bypassing the digestive tract, IV administration enhances therapeutic outcomes and eliminates the risk of digestive issues interfering with treatment. 


Why Intravenous Versus Oral Dosing of Vitamin C?

Oral Ascorbic Acid is absorbed through the intestines in an energy and dose-dependent process, peaking rapidly. At doses over 2g, less than 20% is actually absorbed, leading to gastrointestinal discomfort and diarrhea due to the remaining Ascorbic Acid in the intestinal tract. Recent research indicates that high doses of Vitamin C can have selective cytotoxic effects when given at doses available in intravenous form.


Why IV Vitamin C as a support in cancer care?

Vitamin C is a crucial extracellular antioxidant, playing a role in numerous biochemical reactions in the body. Supportive therapy with Vitamin C has been validated through case studies, preclinical trials, and cancer cell research. These studies have demonstrated that Vitamin C functions in the following ways:

  • Chemosensitization: Ascorbic Acid has been tested in combination with various chemotherapeutics in tissue cultures and animal models. Most well-designed trials have shown a positive enhancement of chemotherapeutic success when combined with Ascorbic Acid. Only a few select studies show negative interactions, and we avoid concomitant therapy in those cases.

  • Inhibition of Tumor Growth and Metastasis: Tumors require specific enzymes to invade and metastasize. Ascorbic Acid has been shown to inhibit these enzymes’ activity and promotes collagen production, potentially stabilizing tumors and preventing local tissue invasion.
